[0002] After the wiring of the existing high-voltage switchgear is completed, in order to check whether the wiring is correct, it usually needs to do many kinds of tests, and different tests need to be connected to different instruments; because there are many and long test lines, and the test lines have voltage line current There are thick wires and thin wires, high-voltage wires and low-voltage wires, so it is easy to wind and miswire the wires, which will not only easily cause test failure, but also easily damage instruments and test objects. For this reason, we have developed a high-voltage switchgear comprehensive test conversion Device, connect this device with various testing instruments in advance, and only need to connect the high-voltage switchgear to be tested to this device during the test, and multiple tests can be performed, thereby reducing the time for repeated wiring and improving test efficiency

The invention relates to a comprehensive test transformation device for a high voltage switch cabinet. The device comprises a controller, a terminal strip and a power supply, wherein the controller is separately connected with an insulation resistance tester, a loop resistance tester, a circuit breaker dynamic characteristic tester and a voltage withstanding tester; the terminal strip is connected with the controller; the power module supplies power to the device; when the device works, the terminal strip is connected with the high voltage switch cabinet to be tested, and the high voltage switch cabinet to be tested is automatically connected with any of the testers via the controller and measured; detectors are connected in advance, and only the high voltage switch cabinet to be tested is connected to the device for multiple tests during testing, so that the repeated wiring time is reduced and the test efficiency is improved.
Description
technical field [0001] The invention relates to the measurement field, in particular to a high-voltage switchgear comprehensive test conversion device. Background technique [0002] After the wiring of the existing high-voltage switchgear is completed, in order to check whether the wiring is correct, it usually needs to do many kinds of tests, and different tests need to be connected to different instruments; because there are many and long test lines, and the test lines have voltage line current There are thick wires and thin wires, high-voltage wires and low-voltage wires, so it is easy to wind and miswire the wires, which will not only easily cause test failure, but also easily damage instruments and test objects. For this reason, we have developed a high-voltage switchgear comprehensive test conversion The device is pre-connected with various testing instruments. During the test, only the high-voltage switchgear to be tested needs to be connected to the device, and multi...
