Sulfur-hexafluoride circuit breaker installing and protecting device

Abstract

The invention discloses a sulfur-hexafluoride circuit breaker installing and protecting device. The sulfur-hexafluoride circuit breaker installing and protecting device comprises a protecting shelter and a draught fan. The protecting shelter is a cuboid-shaped shell body formed by splicing PVC synthetic fiber cloth air bags, the PVC synthetic fiber cloth air bags are of hollow plate-shaped structures composed of composite layers on the inner sides of the PVC synthetic fiber cloth air bags and PVC synthetic fiber cloth on the outer sides of the PVC synthetic fiber cloth air bags, and the composite layers are made of high-strength and multilayer composite materials. According to the sulfur-hexafluoride circuit breaker installing and protecting device, the arranged protecting shelter has a good sealing property, the composite layers arranged on the inner sides can greatly improve the strength of the PVC synthetic fiber cloth air bags and improve the wind-resistant and compression-resistant properties, and a good thermal-insulating effect is achieved; and dehumidifying and heated dry air is pumped in the protecting shelter, wet air is effectively prevented from entering a binding post of a circuit breaker in the installation process, so that the binding post is prevented from being corroded, and the using quality and the safety performance of the sulfur-hexafluoride circuit breaker are improved.

Description

technical field [0001] The invention relates to a protective tent for construction, in particular to a protective device for installing a sulfur hexafluoride circuit breaker. Background technique [0002] Sulfur hexafluoride circuit breaker is a circuit breaker that uses sulfur hexafluoride (SF6) gas as the arc extinguishing medium and insulating medium. Sulfur hexafluoride circuit breaker can be divided into two types in terms of structure, one is the porcelain column type , and the other is tank type. Since the installation and maintenance of sulfur hexafluoride circuit breakers have strict requirements on the environment in order to avoid affecting the contact parts in the circuit breaker, effective dust prevention measures must be taken according to the existing technical specifications. [0003] However, at present, most of the construction sites have not adopted dust-proof devices. Some steel pipes and brackets are covered with plastic films or simple tents are used. ...

Problems solved by technology

[0003] However, at present, most of the construction sites have not adopted dust-proof devices. Some steel pipes and brackets are covered with plastic films or simple tents are used. Inconvenient, which brings hidden dangers to the safe use of sulfur hexafluoride circuit breakers; in addition, for the existing dust-proof tents, they are mostly made of PVC materials or canvas, which have poor strength, especially in the process of repeated disassembly and assembly. In the middle, it is easy to cause damage to the PVC material or canvas, increasing the cost of construction and use
