Direct current contactor insulation performance detection device

Abstract

The invention relates to a direct current contactor insulation performance detection device which is characterized by comprising a cabinet, a compatible detection mechanism, a control switch and an electric control assembly, and the compatible detection mechanism is used for for product positioning and connection testing; thecompatible detection mechanism is arranged on the cabinet. The compatible detection mechanism comprises a sliding assembly, a pressing air cylinder, a probe assembly and a special-shaped cushion block used for fixing the direct current contactor to be detected, the pressing air cylinder is connected with the sliding assembly, and the probe assembly is installed on the sliding assembly. The probe assembly is driven by a pressing cylinder to contact and communicate with a to-be-detected direct current contactor to be installed on the base. A detection station device is installed at the bottom of the cabinet. The detection station device comprises an insulation resistance side instrument group consisting of a plurality of insulation resistance side instruments and a medium withstand voltage tester group consisting of a plurality of medium withstand voltage testers; and the insulation resistance side instrument group and the medium withstand voltage tester group are connected with the probe assembly through output lines in an inserting manner. The previous single-station and single-instrument operation is changed. The working site is saved, multiple purposes are achieved, the working efficiency is greatly improved, and the beat requirement of mass production is met.

Description

technical field [0001] The invention relates to the technical field of DC contactors, in particular to a DC contactor insulation performance testing device. Background technique [0002] A DC contactor is an electrical appliance that uses a small current switch to control a large current. With the continuous expansion of its application fields, such as the continuous expansion of the use in the field of 4G / 5G communication power supply, construction machinery, and new energy vehicles, the application fields of products are also continuously expanding. At the same time, the safety and reliability of products in various fields Sexuality puts forward higher demands. The insulation performance of the DC contactor is one of the important parameters of product safety and reliability, and is generally listed as the A-level quality characteristic of the product. Dielectric withstand voltage and insulation resistance are the two most common and important parameters for the insulati...
