Description
Technical field
The utility model belongs to high-tension switch cabinet technical field, and in particular to a kind of high-tension switch cabinet of insulating radiation type.
Background technology
High-tension switch cabinet refers to for playing break-make, control in electric system power generation, transmission of electricity, distribution, electric energy conversion and consumption
Or the effects that protection, by voltage class in the electric equipment products of 3.6kv-550kv, high voltage isolator and earthing switch, high pressure are negative
Lotus switch, high pressure automatic reclosing and sectionaliser, high-voltage actuating mechanism, high voltage explosion-proof power distribution device and high-tension switch cabinet etc. are several greatly
Class；
China high-tension switch cabinet market is huge, but since manufacturer is large number of, and the switchgear of different manufacturers production exists
Difference in terms of production technology, technical merit, production cost, causes product quality there are larger difference, and product is unsatisfactory for
The case where GB3906 and DL404 standards require is also more universal, wherein the Insulation Problems for opening cabinet with height again are the most prominent, it is to cause
Height opens one of cabinet accident factor the most outstanding.If radiating insulating discharge accident occurs for high-voltage board, harm gently causes equipment
Damage, it is heavy then cause large-area power-cuts, cause irretrievable loss.Therefore, the discharge in insulation hidden danger of high-tension switch cabinet is administered
It is a very urgent task.
