A box-type fixed metal-enclosed switchgear

Abstract

The invention discloses box type fixed metal sealed switch equipment, which comprises a casing, wherein a sleeve communicated with the inside is fixedly sleeved and connected onto one side of the casing; a sleeve ring is movably sleeved and connected onto the outer ring of one end, extending out of the casing, of the sleeve; separation plates in array distribution along the axial line are vertically welded at the outer ring of the sleeve ring; one end, far away from the sleeve ring, of the separation plates is provided with an annular baffle plate welded with the casing; the separation platesand the inner ring of the baffle plate are glidingly connected; a drying box is put between the adjacent separation plates; the outer ring of the bottom of the baffle plate is welded with an air inletcover case; the bottom inner ring of the baffle plate is welded with a press strip of an arc-shaped structure in coaxial arrangement; the top opening position of the press strip is provided with twogroups of clamping mechanisms which are in symmetrical arrangement along the baffle plate; a first passage communicated with the air inlet cover case is arranged above one side, near the air inlet cover, of the baffle plate. The structure is simple; the operation is convenient; the speed is high; the cyclic switching of the drying box is realized; the drying box can be conveniently replaced; meanwhile, during the replacement, the air drying filtering can also be realized.

Description

technical field [0001] The utility model relates to the technical field of switchgear, in particular to a box-type fixed metal-enclosed switchgear. Background technique [0002] Box-type fixed metal-enclosed switchgear is used in three-phase AC 50Hz, 3.6, 7.2, 12kV single-busbar and single-busbar segmental systems for receiving and distributing electric energy, especially suitable for indoor occasions with frequent operations. Traditional box-type The fixed metal-enclosed switchgear needs to be ventilated and cooled when it is in use. When the environment is harsh, such as humid air and heavy dust, it is easy for dust or water vapor to affect the components inside the box-type fixed metal-enclosed switchgear. damage, for which a box-type fixed metal-enclosed switchgear is required. Utility model content [0003] The purpose of the utility model is to solve the shortcomings in the prior art, and propose a box-type fixed metal-enclosed switchgear. [0004] In order to achi...
