An automatic testing device for different types of rcds

Abstract

The invention provides an automatic testing device for RCDs of different types. The automatic testing device for the RCDs of different types comprises fixed shafts, a first locating module, a second locating module, a pushing handle switching-on module and a testing terminal connection module, wherein the first locating module is arranged at one ends of the fixed shafts and fixes the RCDs from the left side; the second locating module is arranged at the other ends of the fixed shafts and fixes the RCDs from the right side; the pushing handle switching-on module is used for switching on the RCDs; the testing terminal connection module is used for being connected with the RCDs in the testing process. The testing terminal connection module at least comprises a first testing terminal connection module, a second testing terminal connection module and a third testing terminal connection module, wherein the first testing terminal connection module is used for being connected with the wiring end of one side of each RCD and comprises four incoming line testing ends; the second testing terminal connection module is used for being connected with the wiring end of the other side of each RCD and comprises four outgoing line testing ends; the third testing terminal connection module is used for being connected with the wiring end on the bottom face of each RCD and comprises two pressing-type testing ends. The automatic testing device can test the RCDs of different wiring end types and different widths, effectively improve the testing efficiency and avoid various operation errors caused by manual operation.

Description

technical field [0001] The invention relates to the technical field of RCD detection, in particular to an automatic testing device for different types of RCDs. Background technique [0002] Residual Current Device (RCD for short) is a leakage safety protection device. Its working principle is as follows: when the person gets an electric shock or the insulation of electrical equipment fails, the vector sum of the current flowing through the RCD main circuit is not equal to zero, and this signal passes through the RCD The secondary winding of the transformer is applied to the judgment actuator. When the leakage signal reaches the preset value of the RCD product, the RCD mechanism moves to disconnect the main contact, so as to disconnect the circuit, and the leakage protection function is realized. According to whether the RCD action needs auxiliary power, it can be divided into two types: electromagnetic type and electronic type. The electromagnetic type does not need auxiliar...
