Embodiment Construction

[0026] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0027] The device for preventing accidental contact and disassembly of terminals of the present invention can be applied in the process of testing and maintenance of power systems in engineering production.

[0028] Such as figure 1 As shown, according to the embodiment of the present invention, the device for preventing accidental touch and disassembly of terminals includes at least one plug-in box 10, and a plurality of plug-in holes 11 are arranged in each plug-in box 10, and the plurality of plug-in holes 11 are independent of each other. It is arranged in the plug-in box 10, and is used to receive the disassembled terminal, that is, the experimenter can insert the temporarily dismantled t...

Abstract

The invention provides a mis-touch and mis-disassembling prevention device for terminals. The mis-touch and mis-disassembling prevention device for terminals comprises at least one plugging box (10), and the plugging box (10) is internally provided with a plurality of mutually independent plugging holes (11) used for receiving disassembled terminals. The disassembled terminals which are temporarily disassembled can be respectively inserted into the plugging holes in the mis-touch and mis-disassembling prevention plugging box, and the mutually independent plugging holes can make the disassembled terminals correspondingly inserted in the plugging holes separated and mutually independent, thereby eliminating the risk of short circuit caused when the disassembled terminals are touched by an external interferent.

Description

technical field [0001] The invention relates to the field of disassembly and maintenance of power systems, in particular to a device for preventing accidental contact and disassembly of terminals. Background technique [0002] Relay protection refers to the anti-accident automation measures for studying power system failures and abnormal conditions that endanger safe operation in order to explore their countermeasures. In order to ensure the safe and effective operation of the power system and avoid power accidents and losses caused by power system failures, electric power testers need to regularly test and repair relay protection devices. [0003] Under normal circumstances, when electric power testers carry out protection verification and accident investigation of relay protection on site, they cannot connect the PT terminal blocks A / B / C / N in the plug-in 10Kv switch protection cabinet (that is, the Three-phase voltage line and ground wire terminal block) to the test posit...
