Abstract

The invention provides a movable integrated test table for a vacuum explosion-proof switch. The movable integrated test table for the vacuum explosion-proof switch comprises a box body, wherein the box body has an L-shaped structure; a power strip, a relay test area, a vacuum alternating contactor clearance adjusting area and a supply voltage output (input) end are sequentially arranged on the upper part of the box body from the left side to the right side; a three-phase synchronous tester and a contact resistance tester are arranged at the lower part of the box body in parallel; and universal wheels are arranged at the bottom of the box body. The three-phase synchronous tester and the contact resistance tester are integrated to achieve accurate and intuitive synchronous test on the suction releasing time, contact bounce and contact asynchronism of a vacuum switch tube so as to judge operating characteristics of a contactor; high voltage output wiring terminals are arranged inside the box body, so that the safety during test is improved; and the universal wheels are arranged below the box body, so that the movable integrated test table for the vacuum explosion-proof switch is convenient to test in a mobile field.

Description

technical field [0001] The invention relates to a detection device, and mainly relates to a movable vacuum explosion-proof switch comprehensive test bench for detecting a vacuum magnetic starter. Background technique [0002] Vacuum magnetic starter is one of the main electrical equipment in coal mines, and it is widely used in the control of mining and transportation machinery. Because it is used underground, there are unfavorable factors such as poor environmental conditions, frequent moving, frequent starting, etc., and many faults will occur during operation, which will affect safe operation to a certain extent. In order to effectively control its faults, fully preventive overhaul. According to the statistics and classification of magnetic starter accidents on site, the highest failure rate is on the three-phase vacuum tube of the vacuum AC contactor, accounting for more than 90% of the total accidents. The main reason is that the pressure spring of the vacuum tube has ...
