Abstract

The invention discloses an easy-to-adjust current loop short-connecting tool, which belongs to the technical field of substation cabinet maintenance auxiliary devices; it includes a connecting plate that can be made of conductive materials and several pins; the pins can be inserted into the interval of electric equipment, and the pins Uniformly installed on one side of the connecting plate; there is also a handle on the connecting plate; There are tenons and mortises that match each other on the sides; the invention effectively solves the problem that the size of the short-circuiting equipment used in the current substation is relatively fixed and cannot meet the operation requirements of terminal joints of different sizes and specifications.

Description

technical field [0001] The invention relates to the technical field of maintenance auxiliary devices for substation cabinets, in particular to a current loop short-circuit tool that is convenient for adjustment. Background technique [0002] In conventional protection substations, especially safety devices such as bus differential protection, stability control and low-frequency and low-voltage decoupling, they are often connected to all bays of the same voltage level, so a set of devices may be connected to as many as 20 or 30 bays . When these equipments are overhauled, it is usually not possible to cut off the power at the same time for all intervals, so a large number of short-circuit current circuits are required. At present, the commonly used method is to use a fixed-length test terminal short-connector. This kind of test terminal short-connector has the following problems in the process of use: 1. It takes about 1 minute for each short-connected group, and the recover...
