Four explosions at Spanish power station

Tuesday, July 12, 2005

Four explosions have rocked a brand new, soon to be online power station in Spain’s Basque reigon in the city of Amorebieta.

Shortly before the blasts, warning calls were made to Basque newspaper Gara and the Basque emergency road service known as DYA, police rushed to the scene and evacuated workers. The calls were made by the Basque separatist group ETA.

There are no confirmations of injuries or structual damage from the blasts at the moment. Spanish radio however reports that there were no injuries and some minor structual damage. Witnesses to the explosions say they were small.

Warning calls before blasts are common by ETA, usually Gara will get the call.

The plant is run by ESB International.

Stepping Motor Heat Treatment Method}

Submitted by: Kitty Chu

Preface: Overheating problem is a general phenomenon for drivers. But what degree of heat is normal , and how to minimize the risk of overheating problems. Continuing to the latter article The Overheat Problems For Stepper Motor

The following is a simple analysis.

The reasons of overheating problems for stepper motor is affected by iron losses, copper losses, even affected by material, current, frequency, voltage. So the overheating problem is showed by iron losses and copper losses. Moreover, AC motor frequency of occurrence of fever is relatively high. But as we said according to the latter essay, the reasonable range of the heating of the https://www.sacer-shop.com/sa1044-dc-motor.html stepper motor depends on the degree to which the motor is hot, depending on the internal insulation level of the motor.

Internal insulation performance is at high temperatures (as long as the internal temperature does not exceed 130? degrees, the motor will not be damaged, so the surface temperature will be below 90 degrees or stepper motor surface temperature is at 70-80 degrees , which are normal temperature for stepper motor.

The simple skills to test the temperature are as following.

Drivers can touch it within 1-2 seconds if the temperature is under 60?. But please just touch it quickly if the temperature is between 70-80?. Drop a few drops of water quickly gasification, then more than 90 degrees.

But the overheating status is also connected to the speed. Stepper motor heating is with the speed of constant change to maintain constant torque output.

Speed to a certain extent, the motor internal back EMF increased. then, The current will gradually decline, the torque will drop automatically.

The solutions of overheating problems for stepper motor.

Solution 1

Increasing the iron losses/copper losses is a good way to avoid the overheating problems. So we can reduce current and resistance. We should choose a small resistance and small current rating of the motor when we decide to purchase it. For two-phase motors, the parallel motor can be used without a parallel motor, but this is often in conflict with the requirements of torque and high speed.

Solution 2

For a motor that has been selected, we should take advantage of the drives automatic half-flow control function and offline functions. The former automatically reduces the current when the motor is in static state. The latter one, we can cut off current directly.

Solution 3

Besides, Segment the drive current waveform close to the sine, If the harmonic less, the motor will be less heat. Increasing the iron losses is also related to the voltage.

High-voltage drive motor will bring high-speed characteristics of the upgrade but increasing the overheating problems.

Solution 4

Choosing the appropriate drive-voltage-grade, Taking into account the high band, smoothness and overheating problems, noise and other indicators

Recommend time for reader, now.

Today, editor will introduce a DC Motor for customers. It is a good quality. Because after finishing the test and retest , the item has obtained a lot of good feedback from our customers.

Please follow us if you want to know more information about stepper motor, For example, How to choose a correct stepper motor? What factors effect the overheating of step motor? How could we solve and avoid the overheating problems? and so on . we will update the article later.

20 confirmed dead after Kintampo freak tree accident

Tuesday, March 21, 2017

A freak accident caused twenty deaths and some injuries, according to officials, at the well-known Kintampo waterfall, in Ghana, on Sunday afternoon local time. Those affected were reportedly school students from Wenchi Senior High School on a supervised trip, and several tourists, who were swimming at the time of a rainstorm and strong winds, bringing down a tree and crushing victims.

Eighteen students, according to Ghana National Fire Service spokesman Prince Billy Anaglate, were killed at the falls, while another two were rushed to hospital and died in care. Varying reports indicated possibly up to 18 people remaining in a critical condition who were trapped under the tree, who were then rescued and rushed to hospital, including a Wenchi Senior High School administrator.

Anaglate said the wind uprooted trees, which fell on swimmers.

Students’ bodies have been sent to the Kintampo Municipal Hospital’s morgue.

Congressman Cunningham admits taking bribes

Monday, November 28, 2005

U.S. Representative Randy “Duke” Cunningham (RCA) pled guilty today to conspiring to take bribes in exchange for using his influence as a member of the House Appropriations Committee to help a defense contractor get business. In total he pled guilty to one count of income tax evasion and four counts of conspiracy, namely mail fraud, wire fraud, bribery of public official and accepting bribes. U.S. District judge Larry A. Burns scheduled Cunnigham to be sentenced on February 27. He is facing up to 10 years in prison and nearly $500,000 in fines, as well as forfeiture of unspecified amounts of cash and property.

In the court hearing, Cunningham admitted to accepting “bribes in exchange for performance of official duties” between “the year 2000 and June of 2005”, taking “both cash payments and payments in kind” and following up by “trying to influence the Defense Department”.

The federal investigation against Cunningham was triggered by his sale of his California residence to defense contractor Mitchell Wade in late 2003. However, Wade never moved in and sold the house at a $700,000 loss three quarters of a year later. At the same time Wade’s company MZM won tens of millions of dollars in defense contracts. Subsequent investigations discovered more questionable business transactions, including interactions with the defense contractor ADCS. In his plea agreement he testified that, among other charges, he “demanded, sought and received at least $2.4 million in illicit payments and benefits from his co-conspirators in various forms, including cash, checks, meals, travel, lodging, furnishings, antiques, rugs, yacht club fees, boat repairs and improvements, moving expenses, cars and boats.”

Cunningham announced his resignation after the hearing. In a written statement released by his law firm O’Melveny & Myers LLP he declared “The truth is — I broke the law, concealed my conduct, and disgraced my high office. I know that I will forfeit my freedom, my reputation, my worldly possessions, and most importantly, the trust of my friends and family.”

Commonwealth Bank of Australia CEO apologies for financial planning scandal

Thursday, July 3, 2014

Ian Narev, the CEO of the Commonwealth Bank of Australia, this morning “unreservedly” apologised to clients who lost money in a scandal involving the bank’s financial planning services arm.

Last week, a Senate enquiry found financial advisers from the Commonwealth Bank had made high-risk investments of clients’ money without the clients’ permission, resulting in hundreds of millions of dollars lost. The Senate enquiry called for a Royal Commission into the bank, and the Australian Securities and Investments Commission (ASIC).

Mr Narev stated the bank’s performance in providing financial advice was “unacceptable”, and the bank was launching a scheme to compensate clients who lost money due to the planners’ actions.

In a statement Mr Narev said, “Poor advice provided by some of our advisers between 2003 and 2012 caused financial loss and distress and I am truly sorry for that. […] There have been changes in management, structure and culture. We have also invested in new systems, implemented new processes, enhanced adviser supervision and improved training.”

An investigation by Fairfax Media instigated the Senate inquiry into the Commonwealth Bank’s financial planning division and ASIC.

Whistleblower Jeff Morris, who reported the misconduct of the bank to ASIC six years ago, said in an article for The Sydney Morning Herald that neither the bank nor ASIC should be in control of the compensation program.
