Embodiment Construction

[0069] Such as figure 1 As shown, the present invention provides a portable relay test device. Eight types of relay test bases are set on the test box, which can test JSBXC1-850 programmable time relays, JWXC-1000 series, JZXC-480 series, JWXC -100 series, JZXC-H18 series, JJJC4 series, JJJC series, JJC series relays are tested separately.

[0070] Test device of the present invention, before starting up, must test box be connected with console (test box is to insert tested relay, and console is for operation detection usefulness), and the power lead wire on the console is inserted into the power supply on the wall, closes Turn on the main switch and start the test. After recording the test data, reset the voltage regulator of the test device to zero, disconnect the main switch, and shut down after the test is completed. Test preparation, including: check whether the voltage regulator is zeroed, whether the main switch is in the disconnected position before use, whether the ...

Abstract

The invention relates to a portable relay test device and method. The test device is provided with an AC-DC voltage conversion and voltage level conversion switch K1, an AC-DC signal input conversionswitch K2, and a type selection switch used for performing front ring, back ring and series connection method switching of to-be-tested relays, wherein a voltage regulator is connected with a power transformer, multiple secondary coil segments of the power transformer are directly connected with an AC output end through the switch K1 and the switch K2, the other path is connected with a DC outputend by a bridge rectifier plate through the switch K1 and the switch K2, and a test time table, a timing switch, a time selection switch and a uniformity test and time test conversion switch, a relayclosed in the DC shift, and a test resistor are further included. The test device is advantaged in that joint point resistance, electrical characteristic, time characteristic and joint point uniformity test of multiple types of safety relays are performed, test efficiency is effectively improved, and cost is saved.

Description

technical field [0001] The invention relates to a portable relay testing device and a testing method, which are suitable for testing domestic safety relays. Background technique [0002] As the first guarantee of urban rail transit signals, safety relays play a pivotal role in the operation safety of subway rail transit. After decades of application tests in the Shanghai subway rail transit site, it has been proved that the safety relay is safe, reliable, and stable in performance, and can meet various requirements of the signal circuit for the relay. It is the main stereotyped product of my country's railway signal relay. [0003] At present, the daily maintenance and testing of safety relays is mainly carried out by the relay team. Due to the use of safety relays in Shanghai Metro, the number of actions is high and the frequency of use is high. Some relay line failures are unavoidable. For the troubleshooting of safety relays, the line duty personnel replace suspected fau...
