HZTC Series High Voltage Hipot Control Station

HZTC series hipot control station is a complete set of equipment of high voltage test transformer, it and the test transformer carry out resistance pressure and leakage test.

Usage and Maintenance

1．When you open the box, you need to check whether it’s in good condition or not, especially you need to check whether the connection ports become loose or not, and the carbon brush connects with the voltage adjustor well or not.

2．Strictly follow the procedure, please read the manual first.

3. If it has been not in use for a long time, you should check main circuit floor insulating resistance by 2500V MΩ meter, and the data should not below 1.5MΩ.

Supplementary Explanation

HZTC series control station is another set of equipment of light test transformer, it has characteristics, perfect capacity, beautify appearance, small volume, light weight, beside, also has the function of switch on and timing, which manual explanation is same as TC control station.

1、Over-current rated value= Over-current relay dial reading ×K

Among which, K is as a state value of change/excise (-SA) switch of current power, respectively for as 1, 2, ∞., K of the switch in ×1、×2 shift is as 1 and 2 respectively, excise shift is as +∞(in normal condition without using it to avoid damaging the equipment due to lost the protection for transformer.

2、Electric control station is normally above 30KVA. As for client convenience, it adopts the methods of increasing voltage, decreasing voltage. The method of voltage increasing is same as manual, firstly fast, secondly slow. When the required voltage of increasing voltage is coming, don’t press the button forever, it’d better loose a little (press and loose by turns). During the voltage decreasing, press the button of decreasing voltage until charcoal brush back to zero, then the zero signals light is on, you can press the button of stop. Finally, shut off the general switch (air switch).

3、Panel drawing of control station and connection drawing, see the annex.

4、This control station could measure the high voltage leak current of the tester. Please measure the high voltage leak current after accomplish the test of the AC voltage during in using to prevent occurring short circuit phenomenon and produce high voltage which exist dangers for operator. The specific procedure is as following:

First, connect the back connection board of the control station in specific wire, and then carry out the AC voltage test. Second, link the high voltage end part of the control station and test transformer (see the wiring sketch drawing in the next page) namely could read the value of the high voltage current.
