Strong and weak current comprehensive testing device

Abstract

The invention discloses a strong and weak current comprehensive testing device, and the device comprises a tool body. The device also comprises a strong current tester which is disposed in the tool body and is used for detecting strong current equipment, a weak current tester which is used for detecting weak current equipment, and a counter which is disposed on the surface of the tool body. The strong current tester is in signal connection with a probe group through a first relay, and the weak current tester is in signal connection with the probe group through a second relay, thereby forming one set of probe group for the strong and weak current comprehensive testing. The counter is in signal connection with the probe group, and the first and second relays are controlled to be on / off through a second switch. According to the invention, the device can improve the testing efficiency and safety, reduces the cost, and improves the detection capability.

Description

technical field [0001] The invention relates to the field of strong and micro-current testing, in particular to a comprehensive testing device for strong and weak current. Background technique [0002] At present, manufacturers of zero-sequence mutual inductors and filter inductors are still using traditional methods for testing. The traditional methods include phase testing and high-voltage testing and are discrete testing. The traditional testing efficiency is extremely slow and labor costs are relatively high. high and prone to misjudgment. [0003] In the industry, the required automatic testing equipment can only be obtained through custom-made, which makes the price expensive, poor compatibility, molds and products must be matched one by one, and consumes electric energy and gas energy. Therefore, the existing technology needs to be improved. Meet the needs of diversified product manufacturing. Contents of the invention [0004] The object of the present invention ...
