Embodiment Construction

[0027] 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 embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] See figure 1 , a schematic diagram of the structure of a power distribution terminal relay protection test wiring adapter 10 in an embodiment of the present application. The power distribution terminal relay protection test wiring adapter 10 includes: a first adapter 100, a conductive cable 200 and The second adapter 300.

[0029] Wherein, the first adapter 100 includes four columnar conductive terminals 110 , which are arranged independently at intervals from each other. When the first adapter 100 is connected to the test equipment, the four columnar conductive terminals 110 are electrica...

Abstract

The invention relates to a power distribution terminal relay protection test wiring change-over arrangement, comprising a first adapter, a second adapter and a conductive cable. The first adapter comprises four columnar conductive terminals that are independently spaced apart from each other, and the four columnar conductive terminals can move relative to each other. The conductive cable comprisesfour conducting wires, each conducting wire is electrically connected with one of the columnar conductive terminals. The second adapter comprises four conductive ends, and each conducting wire is used for electrically connecting one of the columnar conductive terminals with on of the conductive ends. A current circuit of a relay protection test is quickly turned on, so that the wiring time consumption can be maximally reduced. By setting identifiers for distinguishing current terminals, a short circuit caused by mutual collision of the current terminals is avoided, or equipment damage causedby confused wiring is avoided. Accordingly, the power distribution terminal relay protection test wiring change-over arrangement provided by the invention has the advantages of simple wiring, convenient implementation, good safety and reliability, and low cost.

Description

technical field [0001] The invention relates to the field of testing of power distribution terminals, in particular to a connection switching device for relay protection tests of power distribution terminals. Background technique [0002] In the distribution network system, in order to improve the reliability of the distribution terminal, it is necessary to conduct a relay protection test on the distribution terminal. At present, most of the commercial power distribution terminals are fully sealed, and the test terminal needs to be connected to the terminal of the power distribution terminal during the relay protection test. Due to the narrow space of the terminals, it is easy to short-circuit each other, causing equipment damage or personal injury. Therefore, there is a great risk in the relay protection test or handover test, which seriously threatens the personal safety of the test personnel. [0003] In order to reduce the risk of electric shock and equipment damage dur...
