High security waterproof low-voltage switch complete equipment

Abstract

A complete set of high-safety waterproof low-voltage switchgear, including a switchgear door panel, a switchgear cabinet body and a switchgear door frame, a first seal is provided on the switchgear door frame, a second seal is provided on the switchgear door panel; the first seal The first rubber strip made of rubber elastic body and the second rubber strip made of rubber elastic body are arranged on the part; the third rubber strip made of rubber elastic body is arranged on the second sealing part; The observation window includes a glass plate and a reinforcement plate from the inside to the outside. There are multiple observation holes on the reinforcement plate. Three different sealing strips are used to cooperate with each other to achieve multiple seals and effectively ensure its sealing and waterproof performance. The special observation window design uses a reinforced guard plate outside the glass, and adopts a number of regular hexagonal observation holes to enhance the protection performance and allow normal observation at the same time.

Description

technical field [0001] The invention relates to a complete set of switch equipment, in particular to a complete set of high-safety waterproof low-voltage switch equipment. Background technique [0002] In order to prevent dust, foreign matter or moisture from entering the interior of the switchgear, which may cause performance degradation or damage to the internal components of the switchgear. The use of sealed switch cabinets is becoming more and more extensive, so the requirements for sealing are getting higher and higher. However, in the current market products, the waterproof sealing structure of most switch complete sets of equipment is only to add a sealing strip at the gap between the cabinet body and the cabinet door. This method makes the sealing performance worse due to the single strip structure of the sealing strip. Without a good guarantee, it is increasingly unable to meet the increasing sealing standards. [0003] In order to be able to observe the internal ...

Problems solved by technology

However, in the current market products, the waterproof sealing structure of most switch complete sets of equipment is only to add a sealing strip at the gap between the cabinet body and the cabinet door. This method makes the sealing performance worse due to the single strip structure of the sealing strip. Not well guaranteed, increasingly unable to meet ever-increasing sealing standards

[0003] In order to be able to observe the internal operation and use of the switchgear well, there is usually an observation window on the switch cabinet body or door. Generally, the observation window is made of glass. Due to the fragility of the glass, once an accident occurs when the glass is used If the force is too large, the glass is easy to break, causing safety hazards
