Product description:

HTDY-H is the special power supply which designed for inspect and repair high-voltage circuit breakers.

The high voltage switch operating voltage test (commonly known as "low voltage test") is a basic preventive electrical test to ensure the safe operation of the high voltage circuit breaker of the power system. At present, the power sector basically uses the following two methods to test:

1. Use the DC system of the field control cabinet as the test power supply, and test the voltage by the sliding line varistor. The biggest drawback of this method is that if the field test wiring is short-circuited or DC direct grounding, it will directly affect the entire DC system on site. Lightly, the high-voltage equipment on the site loses protection, and the on-site DC system collapses.

2. Using the field AC power, using a voltage regulator for simple silicon rectification and direct output DC, the disadvantages of this method are:

1 The regulator is heavy, inconvenient to use, and the output DC ripple is large.

2 The input and output are not isolated, and the outer casing may be charged, which endangers personal safety.

In view of the above situation, our company has developed a new generation of high-voltage switch-closing power supply, which provides test power for on-site high-voltage switch and opening and closing operation test, avoiding the direct use of DC system in the field control box, effectively preventing possible DC on site. The hazards formed by the system provide conditions for the safe operation of field devices.

Product Features:

1. High-voltage switch dynamic characteristic tester is a special power supply designed for testing and repairing high-voltage circuit breakers and their operating mechanisms.

2. The input and output are completely isolated, and the output DC is stable and reliable.

3, the ripple coefficient is small

4, overcurrent and overvoltage protection

5, the wiring is simple, easy to operate

6, beautiful appearance, light weight, easy to carry
