The relay pressure-resistant test system
Technical field
The utility model relates to a kind of test macro, particularly a kind of relay pressure-resistant test system.
Background technology
Existing relay pressure-resistant test system carries out secondary connection work by operating personnel's butted line joint pin and finishes test, the process need of a relay voltage-withstand test spent about 30 minutes, testing efficiency is very low, and for the configuration of the difference of different relays or identical relay, according to the difference of relay wiring connection layout and the different mode of connection of needs makes the test wiring of relay be not easy to keep and safeguard.
The utility model content
Technical problem to be solved in the utility model provides a kind of relay pressure-resistant test system, and it improves testing efficiency, is convenient to keep and safeguard the test wiring of relay in addition.
For solveing the technical problem, the utility model provides a kind of relay pressure-resistant test system, it comprises control enclosure, passage a-b box, terminal link block and Hi-pot Tester, control enclosure comprises interconnective pilot lamp and Programmable Logic Controller, one end of Programmable Logic Controller is connected with the passage a-b box, the passage a-b box is connected with the terminal link block, and the other end of Programmable Logic Controller is connected with Hi-pot Tester.
Preferably, described terminal link block is connected with an end of a relay, and described Hi-pot Tester is connected with the other end of this relay.
Positive progressive effect of the present utility model is: the utility model relay pressure-resistant test system improves testing efficiency, can in time find test problem in addition, convenient debugging and maintenance.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model relay pressure-resistant test system.
Embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model relay pressure-resistant test system comprises control enclosure 1, passage a-b box 2, terminal link block 3 and Hi-pot Tester 4, control enclosure 1 comprises interconnective pilot lamp 11 and Programmable Logic Controller (PLC, Programmable Logic Controller) 12, one end of Programmable Logic Controller 12 is connected with passage a-b box 2, passage a-b box 2 is connected with terminal link block 3, terminal link block 3 is connected with an end of relay 5, the other end of Programmable Logic Controller 12 is connected with Hi-pot Tester 4, and Hi-pot Tester 4 is connected with the other end of relay 5.Passage a-b box 2 adopts modular construction, and passage a-b box 2 has six modules.In addition, can make different terminal link blocks 3 according to different relays, the test wiring of relay is convenient to keep and safeguard like this.
Programmable Logic Controller 12 is as key control unit and can send first steering order and second steering order, the first steering order control channel a-b box 2 carries out corresponding passage action, the various high voltages of 4 pairs of relays of second steering order control Hi-pot Tester, 5 output voltage-withstand tests, Hi-pot Tester 4 feedback test results give Programmable Logic Controller 12, and last Programmable Logic Controller 12 outputs to test result on the pilot lamp 11.If a certain pacing examination is not passed through in test process, control enclosure 1 can be controlled not output HIGH voltage of Hi-pot Tester 4, indicates that then the pilot lamp of respective channel becomes Chang Liang not by the passage position of test.The tester comes the concrete reason of analysis of failure according to test result, test again after the eliminating.Like this, the utility model only need spend about one minute the process of a relay voltage-withstand test, improves testing efficiency, can in time find test problem in addition, convenient debugging and maintenance.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
