Product Description
Application
GWR1-0.5 (Chongqing Type) distribution line voltage fuse knife switch suitable for outdoor 500 volts, 50 Hz, as protection and overload protection in low voltage side of transformer, can meet the load transformer, no-load line and rated current under certain condition.
The use of the environment:
The altitude does not exceed 2000 meters.
the ambient temperature is not higher than +40 degree, not lower than -25 degree.
The relative humidity of not more than 85% ( relative to the +25± 5 degree)
no combustion and explosion dangerous. No violent vibration and impact, no serious corrosion of metallic and insulating material chemical sites.
Structural characteristics
The main products from the contact knife, contact, the porcelain bottles, base and other components, each for a set of 3, the product has the advantages of small volume, light weight, easy installation, a contact knife and contact with the spring lock mode, contact is good and reliable, not to break-brake in general vibration condition.verview:
GW1 series of outdoor high-voltage isolating switch ( hereinafter referred to as the isolating switch ) is suitable for outdoor 12KV line, for in a line voltage, no-load time electrical use.
The isolation switch to give full consideration to the different needs of users, a grounding knife and without grounding knife two forms. With a switch, earthing knife with CS - type manual mechanism, can prevent the charged hang grounding and grounding wire close the isolating switch misoperation, operators do not have another hang the ground. The isolation switch to a common type and anti-pollution type two. The anti-pollution isolating switch can lag seriously polluted area requirements, can effectively solve the isolating switch in the operation of the pollution flashover problem. Products meet the requirements of GB1985 and GB/T11022 standard.
Conditions of use
1, altitude not exceeding 1000M;
2, the environmental temperature up to 40 degree, -25degree lower limit;
3, no electrical or chemical reaction gas and steam places;
4, no fire, explosion, pollution of the place;
5, without severe vibration or shock ( as in the hammer, dredging machine ) place.
The main description of structure
Isolation switch consists of three unipolar switch. Each unipolar isolating switch are part of the same, comprising a base, supporting and operating insulator, and a static contact, the knife and the arc angle etc.. According to user needs, with a grounding knife with CSoperating mechanism, without ground hair, with CS8-5 type actuator. Products from the large, simple and reliable operation.
When there is no circuit breaker or circuit breaker fault line, isolating switch allows for integration in the following circumstances;
Points on the charging current bus equipment;
Closing the no-load current of power transformer is ( the transformer capacity not exceeding 750KVA ).
