40.5kV Gas Insulated Switchgear Combination switch HGIS

ZH -40.5/2500-31.5 type composite electrical appliance
HGIS (abbreviated as HGIS) is a three-phase AC high-voltage transmission and transformation equipment. This should be set
The backup mainly includes circuit breakers, three position isolation/grounding switches, and electrical
Basic components such as current transformers, outlet bushings, and control cabinets are required
It is also possible to combine maintenance of grounding switches, voltage transformers, and oxidizers
Electrical components such as zinc lightning arresters and fuses. HGIS can be customized according to user needs
Various main wiring methods are required to be combined for use in power transmission and transformation systems
Unified division and integration of no-load, load and fault current, load conversion, isolation
Line, grounding protection, and measurement of electricity consumption, etc

Introduction:

1.  This kind of GIS has good ability of switch-on and switch-off, it can break short circuit current of 50kA without

     shunt capacitor, the breaker is single fracture and the interrupter room is adopted single voltage, bidirectional

     and synchronized wind blowing. 

2.  The ability of witch-off is rather good, the insulation level is very high and the breaker can switch on and off

     20 times without maintain. 

3.  The flow is very good and the breaker does not need any springs and the contactor of spiral spring and

     silver coating all guarantee the flow and the high conductivity. 

4.  The insulation pole has good strength and can endure electricity and impulse, the mechanical longevity is

     5000times. 

5.  It has outstanding operation motors, one kind HMB-4 is hydraulic structure made by , the other is made

     by

6.  It has good adoption into zones of low temperature and can be used humid and badly polluted areas.

1. HGIS adopts a box type structure, with miniaturized and integrated components, and compact equipment, which greatly saves installation land.
2. Advanced technology and reliable operation:
3. Complete interval overall transportation, overall installation, on-site connection, fast and simple, with sufficient quality assurance, greatly reducing the construction period.
4. Meet the development requirements of environmental protection and intelligence:
a. Solved the reliability problem of isolation/grounding switch operation: in SF6 gas, operation is not affected by external environment; Advanced contact and finger structures enable conductive electrical contact
Small resistance, uniform current distribution, and no overheating phenomenon; Adopting a three station structure naturally achieves logical interlocking between DS/ES, eliminating the possibility of misoperation.
b. Each phase is an independent chamber, without the need for insulator partitions, reducing weak insulation and sealing links, and improving the overall reliability of the product.
c. Adopting a built-in through core current transformer, it is not affected by the environment, located between grounded shells, and not affected by high voltage, ensuring safe and reliable operation.
a. The reduction in volume, gas consumption, and the number of components greatly decrease, which is beneficial for environmental protection and resource conservation.
b. Integrated design and intelligent application: In order to meet the increasingly intelligent requirements of the power grid, products can adopt electronic photoelectric transformers or be designed according to
Users require various smart devices to meet their requirements.
