Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] like figure 1 As shown, in the simulation test process of the protection device, the programmable automatic wiring device 2 is connected with the tester 1 and the protection devices A and B under test. According to the type of transmission signal, the programmable automatic wiring device is divided into three major areas, namely the analog signal transmission area, the input signal transmission area and the output signal transmission area. The programmable automatic wiring device connects the input terminal with the signal source of the tester through a special cable, and the device is divided into three types of plug-in boards through cables inside the device. The internal cable connection information is as follows: figure 2 show...

Abstract

The invention relates to an automatic programmable wiring device for protecting a simulation test. The device comprises a programmable control card in control connection with a simulation channel selection loop, an input channel selection loop and an output channel selection loop, wherein one end of the simulation channel selection loop is used for controlling selection connection with analog quantity wiring ends of a first to-be-detected protection device and a second to-be-detected protection device, the other end of the simulation channel selection loop is connected with an analog quantitywiring end of a tester, one end of the input channel selection loop is used for controlling selection connection with input wiring ends of the first to-be-detected protection device and the second to-be-detected protection device, the other end of the input channel selection loop is used for connecting with an input wiring end of the tester, one end of the output channel selection loop is used forcontrolling selection connection with output wiring ends of the first to-be-detected protection device and the second to-be-detected protection device, and the other end of the output channel selection loop is used for connecting with an output wiring end of the tester. The automatic programmable wiring device is advantaged in that the automatic device wiring process can be realized through the programmable control card, test wiring steps are simplified, and the automatic programmable wiring device is not easy to generate faults.

Description

technical field [0001] The invention relates to a programmable automatic wiring device for protection simulation test, which belongs to the technical field of power system relay protection test. Background technique [0002] With the vigorous development of the power system, the performance of the relay protection device is directly related to the safety and reliability of the substation operation, so the performance test of the relay protection device is becoming more and more important. At present, for the test of relay protection devices, most of the methods in the market are to test the devices one by one through manual wiring. For each device to be tested, it is necessary to manually build the wiring circuit once and manually connect the power amplifier box once. The operation is cumbersome and error-prone. There are also certain requirements for the electrical knowledge and skill level of the testers, especially when the relay protection is tested locally, the wiring o...
