Problems solved by technology

[0003] In the prior art, the test of the relay usually needs to use an ammeter and a voltmeter to connect in the circuit of the relay under test, then observe the action of the relay, record the values ​​of the ammeter and voltmeter when the relay is in action, and calculate the operating power of the relay, however, Since the trigger action of some relays cannot be observed with the naked eye, the relay cannot be detected by the above method

Abstract

The invention discloses a detection system, which relates to the field of relay detection and is used for detecting the operating voltage and operating power of a relay more conveniently and accurately. The main technical scheme of the invention is as follows: the detection system includes a DC power supply, a control switch, an indicator and a power meter, the control switch and the indicator are connected in series to the DC power supply, the control switch and a series circuit of the indicator are connected in parallel with a detected relay, the power meter is connected to the detected relay for detecting the power of the detected relay, a control end of the control switch is connected to the detected relay, and when the detected relay operates, the control switch is controlled to be closed, so that the indicator sends out an instruction signal. The detection system of the invention is mainly used for testing the operating voltage and operating power of the relay.

Description

technical field [0001] The invention relates to the field of relay detection, in particular to a detection system. Background technique [0002] A relay is a commonly used electrical control device. It is an automatic switch that controls the operation of a large current through a small current. It is usually used in an automated control circuit. Before the relay is used, the performance of the relay needs to be tested. According to the power industry standard, the operating voltage of the relay is 55% to 70% of the rated voltage, and the operating power of the relay acting on the exit trip circuit must be greater than or equal to 5W, so that it can Ensure safety and put into operation. [0003] In the prior art, the test of the relay usually needs to use an ammeter and a voltmeter to be connected in the circuit of the relay under test, then observe the action of the relay, record the values ​​of the ammeter and voltmeter when the relay is in action, and calculate the actio...
