Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] From the description of the background technology, it can be seen that in the process of regular maintenance and overhaul of the terminal box in the prior art, the disconnection type safety measures are usually adopted to ensure the safety of personnel, that is, the disconnection of the wiring is carried out to realize power-off, protection and connection of test equipment, etc. , but this method requires extremely high skills for operators and is prone to misconnection. Once a misconnection causes the protection to fail, it may cause a safety accident.

[0029] Therefore, in order to solve the above problems, the application provides a terminal box, referring to figure 1 and figure 2 , the term...

Abstract

The embodiment of the present application discloses a terminal box. The terminal box includes: a box body and a terminal module, a relay protection module, and an area module arranged in the box body; the terminal module, relay protection module, and area module are all set There are multiple, the terminal module is set in one-to-one correspondence with the relay protection module and the area module, the terminal module is arranged between the relay protection module and the area module, and the area module has an independent The circuit segment of the circuit. Using the aforementioned scheme, the regional module is designed to form an independent circuit section for independent safety operation, which is beneficial to the safety operation and reduces the possibility of misconnection and mistouch.

Description

technical field [0001] The present application relates to the technical field of power systems, and in particular to a terminal box. Background technique [0002] The terminal box is a kind of interface device for switching construction lines, marking branch lines, and providing convenience for wiring and checking lines. In some cases, in order to facilitate construction and debugging, short-circuit isolators can be installed in the terminal box. Due to the large number of lines in the terminal box and the general use environment is relatively complex, the terminal box needs regular operation, maintenance and inspection to ensure the safety of electricity use. [0003] During the regular maintenance and overhaul of the terminal box, it is necessary to ensure the safety of the operators. The traditional terminal box adopts disconnection safety measures for the operation, maintenance and inspection of the terminal box. However, the disconnection safety measures require extre...
