Rail transit locomotive safety circuit relay function test equipment and method

Abstract

The invention discloses rail transit locomotive safety circuit relay function test equipment which comprises an equipment power supply (1) forming an integrated structure with a tool test work box (4). The tool test work box (4) comprises a box body (401), a box cover (402), a vertical partition plate (406) and a transverse partition plate (404), and the box cover (402) is provided with an indication lamp (5), a contact operation switch (6) and a coil operation switch (7). The box body (401) is movably connected with the box cover (402) through a hinge (403). The equipment power supply (1) comprises a current coarse adjustment part (103) and a current fine adjustment part (104), and the equipment power supply (1) comprises a voltage fine adjustment part (112) and a voltage coarse adjustment part (113), so that the high-precision test of the locomotive safety circuit relay is realized. The invention also discloses a corresponding test method. According to the test equipment, the function test of a plurality of sets of locomotive safety circuit relays is realized at the same time, and the intelligent degree and efficiency of the test work are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of relay testing, and more particularly relates to a relay function testing device and method for a rail transit locomotive safety circuit. Background technique [0002] With the acceleration of urbanization in our country, urban rail transit in major cities has begun to develop in the direction of intelligence and low carbonization. In order to improve the level and operation efficiency of urban rail, strengthening the intelligent development of urban rail maintenance has become a top priority. The locomotive safety circuit relay is a kind of electric control device. When the change of the input quantity meets the specified requirements, the controlled quantity will undergo a predetermined step change in the electrical output circuit, and it has an interactive relationship between the control system and the controlled system. . It is essentially an "automatic switch" that uses a small current to control t...

Problems solved by technology

Existing relay tests need a period of time to complete the test. When a large number of relays need to be tested, it is necessary to equip a large number of test devices to test one by one with the relays. Most of the tests directly place the relays on the relays. The surface of the column is tested, so the stability of the relay is relatively poor. When a collision occurs accidentally, it is easy to knock the relay down, which greatly reduces the test efficiency of the relay.
