Submerged arc furnace low-pressure filtering energy-saving cabinet with push-pull type reactance handcart

Abstract

The invention provides a submerged arc furnace low-pressure filtering energy-saving cabinet with a push-pull type reactance handcart, and the cabinet comprises a cabinet body. The interior of the cabinet is provided with a capacitor bank and a reactor group, wherein all reactors of the reactor group are arranged in the push-pull type reactance handcart in a layered manner. The reactor group is led to a gate-type mobile terminal box through a connection copper bar in detachable connection, a fuse-type isolator and a vacuum contactor. The push-pull type reactance handcart is disposed in the cabinet body in a movable type through a pulley and sliding rail mechanism. The beneficial effects of the invention lie in that the reactor group is integrally disposed in the push-pull type reactance handcart, the disassembly and assembly are convenient, and the workload of maintenance is greatly reduced; a conductive connection structure is reasonable, the routing is clear, the space in the cabinet is used completely, and the heat dissipation effect is guaranteed; the installation structure of capacitors is light and exquisite, and the heat dissipation effect is good; a handcart structure is firm, the service life is long, and the machining cost is low; the sliding rail and pulley structure is simple and convenient, and the movement is stable and smooth.

Description

technical field [0001] The invention relates to the technical field of a low-voltage reactive power compensation cabinet for a submerged arc furnace, and specifically provides a low-voltage filter energy-saving cabinet for a submerged arc furnace with a push-pull movable reactance handcart. Background technique [0002] The submerged arc furnace needs reactive power compensation through capacitive reactance and other components. For example, the invention patent No. 201220313688.5 discloses a reactive power low-voltage compensation cabinet for submerged arc furnaces. There are a large number of capacitors and reactors inside. After the reactor is fixed in the reactive power compensation low-voltage cabinet of the hot furnace, it is inconvenient to disassemble and assemble due to the small space of the cabinet. When a reactor is damaged, the maintenance operation is very inconvenient. If the reactor group can be removed from the cabinet The overall extraction will greatly red...

[0002] The submerged arc furnace needs reactive power compensation through capacitive reactance and other components. For example, the invention patent No. 201220313688.5 discloses a reactive power low-voltage compensation cabinet for submerged arc furnaces. There are a large number of capacitors and reactors inside. After the reactor is fixed in the reactive power compensation low-voltage cabinet of the hot furnace, it is inconvenient to disassemble and assemble due to the small space of the cabinet. When a reactor is damaged, the maintenance operation is very inconvenient. If the reactor group can be removed from the cabinet Pulling it out as a whole will greatly reduce the workload; in addition, the existing low-voltage cabinets for reactive power compensation still have problems such as being too bulky and poor in heat dissipation
