A metal-clad center-mounted removable switchgear

Abstract

The invention discloses metal armor mid-mounted moving type switch equipment, which comprises a casing, wherein a first separation plate is welded to an upper position inside the casing; top plates are welded to the two sides of the casing; an air inlet hole communicated with the inside of the casing is formed in one side, far away from the casing, of the top plate; a fan fixedly connected with the casing is arranged at one end, extending into the casing, of the air inlet hole; an installing opening communicated with the casing is formed under one side of the first separation plate; a wire inlet opening communicated with the casing is formed under the other side of the first separation plate. The equipment has the advantages that the structure is simple; the operation is convenient and fast; the ground is blown so that the ground is dry; the water vapor on the ground is prevented from evaporating to the bottom of the casing, so that the switch equipment corrosion due to water vapor evaporation can be avoided; the external moisture is effectively prevented from entering the inside of the switch equipment; the safe loop switching of the switch equipment is protected; the drying box can be conveniently replaced; meanwhile, the air drying filtering can also be realized during the replacement.

Description

technical field [0001] The invention relates to the technical field of switchgear, in particular to a metal armored centrally removable switchgear. Background technique [0002] "Armoring" is to install a layer of metal protection on the outermost part of the product to prevent the internal utility layer from being damaged during transportation and installation. The metal armored removable switchgear is a type of switchgear, which is characterized by: switch The busbar room, circuit breaker room, cable room, and secondary protection room of the cabinet are relatively independent and separated. The switch compartment is equipped with a handcart switch. The traditional metal armored central removable switchgear is placed on the ground. When it is on the ground, due to the evaporation of water vapor on the ground, the water vapor condenses on the outside of the shell, which is easy to corrode the switchgear. The bottom of the armored central removable switchgear enters the int...

Problems solved by technology

The metal armored removable switchgear is a type of switchgear, which is characterized by: the four compartments of the switchgear, the busbar room, the circuit breaker room, the cable room, and the secondary protection room, are relatively independent and separated. Handcart-type switch, when the traditional metal-armored center-mounted removable switchgear is placed on the ground, due to the evaporation of water vapor on the ground, the water vapor will condense on the outside of the shell, which is easy to corrode the switch equipment. When the removable switchgear is located in the outdoor environment, when rainwater is deposited, the rainwater will easily enter the inside of the switchgear from the bottom of the metal armored removable switchgear and cause equipment damage. For this reason, a metal armored removable switchgear is required. open switchgear
