Embodiment 1

[0027] The invention provides a technical solution: a high-voltage interface protection device for electrical control cabinets, including a cabinet body 1, a partition 2 is vertically arranged in the middle of the cabinet body 1, and a connecting port is arranged at intervals on the upper part of the partition 2 3. The inner side of each connection port 3 is provided with a high-voltage connector socket 4, and the outer side of all connection ports 3 is provided with a protective shell 5;

[0028] Sockets 7 are distributed at intervals on the protective shell 5, and the positions of the sockets 7 correspond to the positions of the connection port 3 one by one. The inner side walls of the socket 7 are symmetrically opened with a receiving cavity 8, and a blocking block 9 is slidably arranged in the receiving cavity 8. A return spring 10 is connected between the back of the blocking block 9 and the receiving chamber 8;

[0029] When the high-voltage wiring is pulled out, the blo...

Abstract

The invention discloses a high-voltage interface protection device for an electrical control cabinet in the technical field of high-voltage interface protection. The high-voltage interface protectiondevice comprises a cabinet body, wherein a partition plate is vertically arranged in the middle of the cabinet body, connecting ports are transversely formed in the upper portion of the partition plate at intervals, a high-voltage joint socket is arranged on the inner side of each connecting port, and protective shells are arranged on the outer sides of all the connecting ports. According to the invention, by arranging the protection shell, the shielding block, the reset spring and the like, the high-voltage interface can be shielded, and the shielding mode is in one-to-one correspondence, sothat the safety of plugging and unplugging the high-voltage wire is improved, the structural design occupies less space in the cabinet body, the design is reasonable, and the structural design also has certain capability of clamping the high-voltage wire so as to improve the connection stability of the high-voltage wire and the high-voltage interface and make the high-voltage wire be not easy to loosen and fall off.

Description

technical field [0001] The invention relates to the technical field of high-voltage interface protection, in particular to a high-voltage interface protection device for an electrical control cabinet. Background technique [0002] The switch control cabinet is a kind of electrical equipment, and its main function is to switch, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The outside line of the switch control cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch, and each branch is set according to its needs. The high-voltage interface in the control cabinet is used to connect to the high-voltage line, but the connection between the high-voltage line and the high-voltage interface will be disconnected before assembly or during maintenance, so that the high-voltage interface is exposed, which is likely to cause fatal electric s...
