Embodiment Construction

[0019] The relay comprehensive test bench simulating the railway and subway operating environment consists of a temperature box work area (1), a vibration shock test bench (6), a test host (10), an electrical tester (12), and a power amplifier of the vibration shock test bench ( 13) and cooling fan (8) and other parts, such as figure 1 shown. A sealed soft connection is adopted between the working area of ​​the temperature box (1) and the vibration shock test bench (6). The temperature of the temperature box working area (1) is controlled by the temperature box (17) and its controller (18). The tested relay (5) is placed in the working area of ​​the temperature box, and fixed on the table top of the vibration and shock test bench (6) by clamps, and the relay is connected with the electrical tester (12) through the test signal cable (15). The electric tester (12) is connected with the test bench host computer (10) through the communication cable (11), and is connected with th...

Abstract

The invention relates to a comprehensive relay test stand for simulating the operating environments of railways and subways, comprising a temperature box working area, a vibration impact test stand, a test host, an electric tester, a power amplifier of the vibration impact test stand and a cooling fan; the temperature box working area and the vibration impact test stand adopt sealed soft connection; the temperature of the temperature box working area is controlled by a temperature box and a controller thereof; the relay to be tested is arranged in the temperature box working area, and the relay is connected with the electric tester by a testing signal cable; the electric tester is connected with the host of the test stand by a communication cable and is connected with the power amplifier of the vibration impact test stand by a control cable; the power amplifier of the vibration impact test stand is connected with the vibration impact test stand by the control cable; and the vibration impact test stand adopts an air cooling mode and is connected with the cooling fan and a silencer by an air pipe. The test stand can reduce the accidents caused by faults of the relay in the running process of the electric locomotives and subway cars.

Description

technical field [0001] The invention relates to a relay comprehensive test bench, in particular to a relay comprehensive test bench for simulating the operating environment of railways and subways. It can simulate the temperature, vibration and shock of the railway and subway operating environment. The vibration and shock parameters meet the requirements of IEC 61373-1999 and the national standard TB / T3058-2002, and complete the electrical test of the relay at the same time. It can be used for comprehensive testing of various relays on electric locomotives and subway vehicles. Background technique [0002] At present, there are various types of relay protection testers on the market, or relay testers, which can test the current, voltage, frequency, differential, impedance, distance, direction, intermediate and time relays commonly used in power systems and test. For electric locomotives on the railway, there is a comprehensive test bench product for locomotive electrical a...
