Improved low-voltage switchgear

Abstract

The invention relates to an improved low-voltage switchgear. The improved low-voltage switchgear comprises a cabinet body, the front end surface of the cabinet body is provided with a cabinet door, alintel is installed above the cabinet door, heat dissipation holes are formed below the cabinet door, a combined handle door lock is assembled on the cabinet door, a main control switch and an outputshunt control switch are installed in the cabinet body, the output shunt control switch is installed below the main control switch, the main control switch is fixed on a mounting beam fixedly connected to the upper portion of the interior of the cabinet body and fixedly connected with wiring rows and a transfer row, the upper end of each wiring row is connected with a lengthening row head, the lower ends of the wiring rows and the lower end of the transfer row are all sleeved with insulated thermal shrinkage pipes, a PE-line ground row and an N-line zero row are arranged below the output shuntcontrol switch in the cabinet body, and grounding screws are welded to the bottom of the cabinet body and the bottom of the cabinet door. According to the improved low-voltage switchgear, multiple cables can be connected at the same time, the space position of the low-voltage switchgear in the depth direction is fully utilized, the improved low-voltage switchgear is very convenient to manufacture, install and use, and the manufacturing cost is reduced.

Description

[technical field] [0001] The invention relates to the technical field of electrical equipment, in particular to an improved low-voltage switchgear. [Background technique] [0002] Low-voltage switchgear is a kind of electrical equipment, which is used to control the opening and closing of various equipment. The external line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. In the prior art, each terminal used for the incoming and outgoing lines of power cables in various electrical cabinets can only be connected to a limited number of cables. However, in some applications, each terminal needs to be connected to many cables. Therefore, with the development of distribution network technology and the continuous growth of the market demand for power transmission and distribution equipment, and with the construction of rural power grid reconstruction and UHV projects, the existing low-voltage s...

Problems solved by technology

In the prior art, each terminal used for the incoming and outgoing lines of power cables in various electrical cabinets can only be connected to a limited number of cables. However, in some applications, each terminal needs to be connected to many cables. Therefore, with the development of distribution network technology and the continuous growth of the market demand for power transmission and distribution equipment, and with the construction of rural power grid reconstruction and UHV projects, the existing low-voltage switchgear cannot meet this demand well.

In addition, in the existing technology, when the low-voltage switchgear is used outdoors, the internal electronic components often cannot work normally due to the influence of the external temperature, and in the hot summer, the sun exposure can easily cause the switch The cabinet body is hot, which affects the performance of electrical equipment, and cannot make good use of these wasted energy
