Product Description

AC  50Hz Power Frequency High Voltage Inductive Resonant Tester HV  Generator withstanding voltage test set 
 

I. Product description

With the development of power system, the capacity of the power operating equipment becomes larger and larger, and the voltage level of the transmission is higher and higher. So the requirement of the test equipment for the running equipment increases. Such as the use of conventional high-voltage test equipment, test equipment and capacity required for testing power supply equipped with the capacity of up to a few thousand KVA, due to test equipment for large capacity, field test, heavy equipment for handling; and because the test power supply capacity, and it is not convenient to find the appropriate power at the scene.
In order to meet the needs of large capacity and high voltage (ultra high voltage) to test electrical equipment, the booster device using a series resonant principle, with adjustable reactor and test equipment (capacitive) or the capacitance compensation capacitor to form a resonant matching. Thus, the test power supply only takes the active component, which is only 1/Q times of the required capacity of the test, and the capacity and weight of the test equipment are greatly reduced. It is an ideal high voltage source.

Hot tag: inductive resonant test set, power frequency resonant test system, stator winding AC hipot tester, high voltage test equipment,AC resonant test system, inductance resonant test system

III.Main Functions

(1)Automatic step-down function when the withstand voltage time is reaching :
Digital timer is used for withstand timing and when reach to withstanf voltage time, the system will automatically step-down
(2) Zero turn on and zero boost:
Zero limit function, if the voltage regulator is not zero, the high voltage output button can not close, and ensure that the system is from zero to step up.
(3) Over current protection function:
The system is equipped with electromagnetic overcurrent relay, this relay anti-interference ability, quick action, to avoid test products not flow damage.
(4) Over-voltage and the flashover protection function
The utility model is provided with an electronic overvoltage flashover protective plate to avoid the damage of the test product not subjected to pressure and flashover, and the action is rapid.
(5) Real-time monitoring function of each test data:
The voltage and current value can be monitored, so that the test can be understood more intuitively.
(6)Phase sequence protection
The main function of the phase sequence protector is to avoid the wrong connection of the three-phase phase sequence of A, B, and C of the input power supply. If the wrong phase sequence protection relay operates, neither the console nor the circuit breaker can be closed; only when the correct phase sequence is connected can it be closed.

V. Trouble shooting

Fault phenomenon	Possible cause	Solution
The console cannot be closed	The phase sequence of the input power supply is Incorrect 2.Over-voltage protection setting is too low or 0V; 3.The zero position of the voltage regulator is not closed	1.Swap the two input power cables at will; 2.Re-set the  overvoltage value; 3.Check the zero baffle and zero switch Can't find resonance point
Can't seek resonance	1.Is the wiring correct or secure 2.Whether the capacitance range of the test product is within the range of use of the device  3.Resonant circuit is not formed	1.Recheck the wiring 2.Re-check the capacitance of the test object 3.Check whether the loop connection is correct and whether the loop ground wire is grounded at one point
