Abstract

The invention discloses a low-current line selection protection device for a high-voltage cabinet. The low-current line selection protection device includes a shell, heat dissipation mechanisms, a base and a lifting mechanism; the lifting mechanism is arranged at the top end of the base; the shell is installed at the top end of the lifting mechanism; a control panel is arranged at the top end of the interior of the shell; a single-chip microcomputer is arranged inside the control panel; movable plates are uniformly fixed inside the shell; limiting mechanisms are uniformly arranged at the top ends of the movable plates; and the heat dissipation mechanisms are arranged at two sides of the interior of the shell respectively. According to the low-current line selection protection device for the high-voltage cabinet of the invention, the overall lifting function of the device can be realized through an lifting rod, electric push rods and a bottom plate; since the whole device is placed on the ground, the electric push rods can be manually operated if a large amount of accumulated water exists on the surface of the ground, and therefore, the whole device can be lifted, and the device isprevented from being submerged and damaged by the water.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a small current line selection protection device for a high-voltage cabinet. Background technique [0002] Small current line selection is a kind of protection equipment used in the power industry. Small current line selection is widely used in large power supply systems such as power plants, hydropower plants, and chemical industries. Its main function is to indicate the line where a single-phase ground fault occurs. Currently There is a small current line selection protection device for high-voltage cabinets on the market, but there are many defects: [0003] First, the traditional low-current line selection protection device for high-voltage cabinets has poor heat dissipation effects. Electrical equipment will generate a lot of heat when operating in a closed space, and the accumulation of heat will cause damage to the internal equipment of the device; [0004] S...
