Description

Asymmetric binding post and binding post row

Technical Field

The utility model relates to the technical field of wiring terminals, in particular to an asymmetric wiring terminal and a wiring terminal row.

Background

The secondary wiring terminal is a connector for electrically connecting the on-screen equipment with the off-screen equipment, so that the inner side of the screen is conveniently connected with the wires on the outer side of the screen. However, in maintenance work of the relay protection system, the current transformer, the voltage transformer and the on-screen and off-screen devices in the outlet loop are required to be insulated. Therefore, tests such as measurement and debugging are carried out on the protection device on the inner side of the screen, and tests of insulation and direct resistance of the loop are measured on the outer side of the screen. The current method for distinguishing the off-screen cable from the off-screen cable mainly depends on the wiring number head code or uses a universal meter to measure and check the wiring. The method not only needs to consume a great deal of time and energy to check secondary wiring, but also can easily cause false outlets aiming at the situations of mishead coding, improper operation of maintainers and the like, and even can cause accidents such as unplanned shutdown of a unit, abnormal tripping of a circuit and the like. The existing CT, PT and outlet loops generally adopt segmented test terminals which adopt symmetrical structures, and a test hole is respectively arranged beside each fastening screw at two ends; the maintenance personnel are inconvenient to intuitively distinguish and warn loops at the inner side and the outer side of the disc in the process of overhauling and debugging, and the risk of false outlet caused by false operation exists; therefore, maintenance personnel are usually required to cover the terminal at the outer side of the screen by using the insulating tape to play a role of precaution and warning, but the insulating tape cannot be reused, and resource waste exists. In order to solve the problems, the utility model provides the asymmetric wiring terminal which can not only effectively prevent misoperation of maintenance personnel from leading to misoperation, but also improve the working efficiency and reduce the resource loss.
