Purpose of High Voltage Switch Mechanical Characteristics Tester
Widely applicable for DC high voltage testing of electrical equipment such as zinc oxide arresters, magnetic blow arresters, power cables, generators, transformers, circuit breakers, etc.
Operating steps for High Voltage Switch Mechanical Characteristics Tester:
1. Use wires to securely connect the grounding screw of the generator and the grounding terminal of the test object to the earth ground wire.
2. Take out the nylon extension rod, wipe it clean, screw it together with the spherical high-voltage ammeter, and insert it into the high-voltage output bushing.
3. Insert the plug of the spare shielded cable into the spherical ammeter (at this time, the meter shows 000), and connect the other end to the test object. (Note: the outer sheath of this cable carries high voltage and must be insulated from ground.)
4. Insert the five-pin plug of the high-voltage generator cable into the control box and tighten it, then plug in the power cord of the control box, turn the voltage adjustment knob counterclockwise to zero, press the start switch, and then adjust the voltage as needed for the boost operation. (This unit is equipped with zero-position interlock and ground protection; it cannot start when the voltage adjustment knob is not at zero, nor when the ground wire is not properly connected.)
5. After testing, turn off the machine, wait for the high voltage to automatically decrease to near zero (the unit is equipped with an automatic discharge resistor for currents greater than 200uA), then use a discharge rod to discharge the test object before unplugging the power plug and proceeding to disconnect the wires.
Product Features
1. Small size, light weight, more aesthetically pleasing, more reliable, easy to operate, and fully functional; it is an ideal replacement product for the new century.
2. Utilizes advanced technology and manufacturing processes, pulse train logic array modulation, high-power IGBT devices, and phase fuzzy control, resulting in higher output stability and smaller ripple coefficient.
3. High precision and accurate measurement. The output voltage adjustment uses a single multi-turn potentiometer, providing a smooth boosting process, high adjustment precision, and coarse and fine adjustment functions. The instrument can measure leakage current at both high and low voltage ends, with the high-voltage end using a spherical shielded digital display that is resistant to discharge shocks and has good anti-interference performance, suitable for field use.
4. The voltmeter on the control box directly displays the voltage applied to the load test object, eliminating the need for external voltage dividers and current limiting resistors, simplifying wiring and facilitating operation.
5. Negative polarity output, zero-start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, return-to-zero, ground protection, and open-circuit protection. The automatic protection is strong, operation is safe, and all technical indicators are superior to industry standards and similar products.
