Alternating current distribution equipment automatic control device based on bimetallic strip principle

Abstract

The invention relates to the technical field of AC power distribution equipment, and discloses an alternating-current power distribution equipment automatic control device based on a bimetallic stripprinciple. The control device comprises a cabinet body, the interior of the cabinet body is rotatably connected with a mounting frame. A branch pipe is fixedly connected to the interior of the mounting frame; the exterior of the branch pipe is fixedly connected with a dry powder tank; the outer part of the branch pipe is rotationally connected with a main pipeline; the outer part of the main pipeline is fixedly connected with a wind pressure machine; the interior of the cabinet body is movably connected with a sealing plate. The top of the sealing plate is fixedly connected with a sealing gear; a sealing motor is movably connected to the outer part of the sealing gear; the interior of the cabinet body is fixedly connected with a shell. A bimetal rod is movably connected to the interior ofthe shell, a control gear is fixedly connected to the top of the bimetal rod, and through cooperative use of the cabinet body and the mounting frame, space occupation of the equipment is reduced, thespace utilization rate of the equipment is increased, space waste is reduced, and the equipment is effectively and conveniently mounted and stored.

Description

technical field [0001] The invention relates to the technical field of AC power distribution equipment, in particular to an automatic control device for AC power distribution equipment based on the bimetal principle. Background technique [0002] AC power distribution equipment is used to connect power supply, transformer, converter equipment and other loads, and monitor and protect the power supply system. The control functions of the operation mode, such as protection, measurement, alarm and power factor compensation, etc. [0003] However, the existing AC power distribution equipment usually has a square cabinet structure, which leads to a large space occupied by the cabinet and low space utilization, and the existing AC power distribution equipment usually uses fuses for circuit monitoring, resulting in slow response to circuit overload , it is easy to cause damage to the internal components of the equipment, and it is troublesome to replace, which leads to certain limi...
