Embodiment approach

[0014] Embodiments of the present invention refer to figure 1 : The test device circuit of the AC relay is composed of the following parts: power switch KA1, KA2, fuse FU1, FU2, transformer, power indicator, voltage regulator BT1, transformer BT2, ammeter A1, voltmeter V1, display indicator HL1 , HL2, HL3, resistors R1-R10, relay sockets KA1-KA2, shock absorbers. 220V AC power is introduced from the primary side of the transformer, and the secondary side of the transformer outputs two sets of AC power, 220V and 6.3V, to provide working power for circuits and indicator lights. The 6.3V indicator light used to indicate the circuit state and the indicator light D1-D4 indicating the working state of the AC contactor, and the current limiting resistor R1-R4, the resistance value of which is 62-10W, where D1-D4 is 220, 200W red, green, Colored light bulbs. One end of the 0-220V voltage regulator B1 is connected to 220, the other end is connected to the AC contactor line package, t...

Abstract

The invention discloses a testing device for alternating-current relays and a testing method thereof. The testing device consists of a power switch, an ampere meter, a voltmeter, a transformer, a voltage regulator, the alternating-current relays, a high-power resistor and output indicator lamps. The testing device provides a function testing platform for detecting the alternating-current relays and the testing method. The mechanism of the testing device is that the working state of the alternating-current relays in a whole circuit is simulated, high-power load is adopted to test the bearing capability and the dynamic working performance of the alternating-current relays under the conduction state, electricity is obtained by utilizing a relay KA coil, and the state of two groups of normally closed contacts changes so as to achieve state convention. If the state convention is not achieved, or the indicator lamp are turned on or turned off simultaneously or are inoperative completely and other situations, the alternating-current relays are defective products and unqualified products. Therefore, the unqualified products are selected out. The circuit can test ten alternating-current relays in one time.

Description

technical field [0001] The invention relates to an air conditioner electronic component testing device and a testing method thereof. It belongs to the field of air conditioners. Background technique [0002] Usually, it is very difficult for the complete machine manufacturer to test the AC relay.
