Product Overview

2014year6moon11State Grid Corporation of China[2014]748Chapter 4 Testing and Inspection of the Management Regulations for Power Safety Tools and Instruments of State Grid Corporation of ChinaSpecific requirements have been put forward for the testing, inspection, and management of safety tools and equipment in the units affiliated with State Grid Corporation of China:

Article 21: Safety tools and equipment shall pass the type tests specified by national and industry standards, as well as factory tests and preventive tests. The testing of imported products shall not be lower than the standards of similar domestic products.

Article 22: Safety tools shall be inspected by qualified safety tool inspection agencies. Preventive testing can be conducted by testing institutions that have obtained internal inspection qualifications through evaluation and recognition organized by the company headquarters, provincial companies, or directly affiliated units, or by commissioning safety tool inspection institutions with nationally recognized qualifications.

Article 23: Strengthen the construction of safety tool testing centers at all levels of the company, improve the work network and system, effectively carry out testing and inspection work, timely discover safety tool defects and hidden dangers, and ensure safe use.

Article 24: The headquarters of the company entrusts a qualified and capable safety tool quality supervision and inspection agency to provide supervision, management, and technical support services for safety tools. Provincial and municipal company level safety tool testing institutions are responsible for the testing, inspection, and technical supervision of safety tools in their affiliated units. County level units with conditions can set up safety tool testing institutions to be responsible for the testing and inspection of safety tools in their own units. Construction enterprises can conduct self inspection or entrust qualified personnel according to relevant national standardsThird party inspection of quality.

State Grid Corporation Chairman Shu Yinbiao attaches great importance to security work,2016year11moon7He delivered a speech in Beijing, stating the requirements for safety work as the first priority for future work;

Firmly establish the awareness of safety first, always sound the alarm like walking on thin ice, vigorously implement safety measures, identify and rectify hidden dangers, enhance basic capabilities, and resolutely curb the occurrence of major accidents.

The key to safety work lies in fulfilling responsibilities.

Improve the level of intrinsic safety.

Strengthen the safety of the homework site.”

In summary, the detection capability of power safety tools has become a key equipment that needs to be equipped in provincial, municipal, and even county-level units of State Grid Corporation of China, in order to meet the detection capability requirements proposed by State Grid Corporation of China.

Features

1The instrument testing method complies withThe requirements of DLT1476 "Preventive Testing Regulations for Electric Power Safety Tools".

2. The test bench adopts an integrated design of manual and automatic control, which can be completed by a computer for all automatic control functions. The automatic testing function can also be completed by turning off the computer and using a test bench.

3. When using computer control, the test voltage and 8-channel leakage current curves can be displayed in real time.

4The experimental process is fully automated, according toThe speed test shall be conducted at a voltage of 1kV/S below 75% of the test voltage and 0.1kV/S above 75% of the test voltage. The test voltage shall be maintained, and the automatic voltage reduction shall be timed and the leakage current shall be recorded. After returning to zero, the power shall be automatically cut off and a prompt shall be given. The test shall end.

5. The equipment has overcurrent, overvoltage, and breakdown protection.

6. The experimental equipment is equipped with a high-voltage hazard warning light display.

7. The instrument adopts a large screen LCD Chinese character display, which displays parameters such as output voltage, input current, high-voltage leakage current, timing time, and Chinese character prompts on one screen.

8. Equipped with insulated boots, gloves, and a pressure resistant platformcarry out simultaneouslyTest with 8 insulated boots or gloves to measure leakage current separately.

9. The insulated boots and gloves pressure table adopts infrared communication patented technology, which completely isolates the operating table from the high-voltage system, ensuring the safety of the testing personnel.

10. The insulated boot glove pressure table has a dedicated grounding container for easy operation.

11. Each test piece on the insulated boots and gloves voltage tester is equipped with a high-voltage breaking mechanism. When any one of the test pieces breaks down, the test piece will automatically detach from the high voltage without affecting the progress of the test

12. Equipped with a wireless remote control electric insulation rod test bracket, it can conduct overall voltage withstand tests on 35kV insulation rods.

13. Equipped with a wireless remote control A-type electric voltage tester test stand, it can perform power supply testing for voltage testers below 35kV.

14. The test bench is equipped with a micro printer that can print test results at any time.

15. Install LED Chinese character safety protection display screen to display test status and test items.
