I. overview

 

 

 

This unique automatic electric power safety and instrument test system is in accordance with the national electric power company about the electricity safety instruments preventive test regulations (trial) to inform (guodian is sent [2002] 777), and state grid electric power security codes (substation) requirements, on the basis of the joint university institute of technology development and production in xiamen, and won the xiamen municipal government science and technology innovation fund for financing. All indexes of the product meet the requirements of national standard. The intelligent insulation voltage withstand test can be carried out for safety instruments such as insulating shoes and insulating gloves according to the precautionary test regulations for electric power safety instruments. The testing period of insulating boots and insulating gloves is half a year. No breakdown is allowed in the test process. The products are applicable to all power related industries.

Testing of insulating shoes and gloves.

 

 

 

Iv. Functional features

 

 

 

1. The instrument can simultaneously test 8 insulating boots or gloves, and measure the leakage current of each sample.

 

 

 

2. The insulation shoe test adopts the dry test method of placing small steel balls inside, which gets rid of the traditional practice of filling water into the shoe for test and is not easy to be dried after the test.

 

 

 

3. The measurement voltage and the measurement current are compared in real time by high and low voltage mutual correspondence to ensure the accuracy of the measurement voltage and current value.

 

 

 

4. High and low voltage separation, leakage current is transmitted back to the control box using anti-interference wireless transmission technology, which greatly protects personal safety.

 

 

 

5. Each test piece has a breaking mechanism. When any one of the test pieces breaks down or exceeds the set leakage current value, the test piece will be separated from the test automatically without affecting other test pieces.

 

 

 

6. The instrument adopts large-screen LCD Chinese characters to display large amount of information. One screen simultaneously displays test voltage, 8-channel high-voltage leakage current, perpetual calendar, timing time and other parameters as well as Chinese prompt contents.

 

 

 

7. Stepper motor with high fineness is used to control the boost process of the voltage regulator, and the voltage withstand test is carried out automatically. After the start of the test, the instrument will automatically close with the voltage boost speed required by the national standard, start timing when the preset voltage is reached, and maintain the test voltage, timing, automatic voltage reduction, and automatic power off after zero, indicating the end of the test, and display the leakage current of each sample, and automatically save the test results.

 

 

 

8. The insulation boots test has a special metal grounding tray, and the insulation gloves test has a special container for easy operation.

 

 

 

9. The test transformer ratio is set freely, which can be matched with the existing transformer of the customer

 

 

 

10. With over-current protection function.
