Abstract
The utility model relates to a device for testing circuit breaker characteristics, which at least comprises a circuit breaker characteristic test apparatus, a circuit breaker to be tested, a matched transfer box, a DC closing input power line and a DC opening input power line. The device for testing circuit breaker characteristics realizes circuit breaker characteristic test by using the matched transfer box to replace a traditional alligator clip, improves the accuracy of test data and enhances the safety of the test method.
Description
Technical field
The utility model relates to a kind of circuit breaker characteristic test unit, belongs to power system device maintenance field.
Background technology
The isolating switch attribute testing is the necessary pilot project of regulation in " power equipment is the prophylactic tria rules routinely " in the electric system at present, usually directly be connected isolating switch self secondary plug-in unit contact pin with direct current separating brake input power supply by crocodile clip with direct current combined floodgate input power cord in the test, there are following three problems in this method of attachment: the first, very little because of distance between isolating switch self the secondary plug-in unit contact pin, crocodile clip positive and negative two is as easy as rolling off a log to cause short circuit, has potential safety hazard; The second, crocodile clip directly is connected with secondary plug-in unit contact pin, and contact area is little, and the data transmission sensitivity reduces, and causes the back-to-back testing data accuracy on the low side; Three, crocodile clip directly is connected with secondary plug-in unit contact pin and need sets up fixedly crocodile clip of special messenger, and work efficiency is not high, waste personnel and man-hour.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and the connected mode of a kind of new DC combined floodgate input power cord, direct current separating brake power lead and tested isolating switch is provided, and has improved test figure accuracy and the security that has strengthened test method.
The purpose of this utility model is finished by following technical solution, described a kind of circuit breaker characteristic test unit, it is at least by the circuit breaker characteristic test apparatus, tested isolating switch, supporting transfer box, direct current combined floodgate input power cord and direct current separating brake input power cord constitute, be connected with direct current separating brake input power cord with direct current combined floodgate input power cord between described testing equipment and the supporting transfer box, supporting transfer box connects isolating switch self secondary plug-in unit contact pin and tested isolating switch by the special purpose interface connecting line, connects with circuit breaker characteristic data acquisition line between circuit breaker characteristic test apparatus and the tested isolating switch.
The left and right sides is fixed with the stainless steel handle on the described supporting transfer box panel, is shaped on power switch, power supply input, input indicator, patchcord output, tripping operation input, the input of closing a floodgate in the middle of the panel, exchanges parts such as output.
Tripping operation input on the described supporting transfer box, the input of closing a floodgate, power input part spare all adopt the cylindrical receptacle design.
The patchcord output that described supporting transfer box is provided with the dedicated pins interface connects patchcord one end, and the patchcord other end adopts primary cut-out dedicated pins interface to connect tested isolating switch.
The design of the outside employing of described supporting transfer box suitcase.
The utility model is by improving the connected mode of test direct current combined floodgate input power cord, direct current separating brake power lead and tested isolating switch, abandon traditional crocodile clip connected mode, use circuit breaker characteristic newly developed to test supporting transfer box and connect, improved test figure accuracy and the security that has strengthened test method.
