1. Performance and use of GZS8 Interval Metal-Enclosed Switchgear,High Voltage Switchgear
GZS8 switch cabinet is a light and flexible switchgear. Simple structure, small number of parts, reliable interlocking, modular design and rear pressure relief channel design make the switchgear more safe and reliable.
- The new generation of air-insulated metal-enclosed switchgear, through continuous innovation, the performance and flexibility of the switchgear can fully meet the ever-changing needs of the market.
- Provides long-term technical solutions for various applications. Safety, convenience and environmental protection are the goals of our switchgear development.
- Compact switchgear suitable for power distribution automation. The use of sensing technology and the latest protection relays enables the switchgear to be used in places with demanding operating requirements.
- Provide the best solution for medium voltage system with small and compact size.
- Suitable for small secondary substations, industrial and mining, enterprises, residential communities, high-rise buildings, schools and parks and other power distribution systems, as indoor AC three-phase 12kV, 50Hz ring network power supply unit and terminal power distribution equipment.
2. Structure of GZS8 Interval Metal-Enclosed Switchgear,High Voltage Switchgear
The whole GZS8 switch cabinet can be divided into two parts, the upper part includes the busbar room, load switch, operating mechanism and low voltage room, which is separated from the lower cable room. The equipment in the upper unit can be overhauled, modified and replaced as a whole safely and conveniently.
3. Busbar room of GZS8 Interval Metal-Enclosed Switchgear,High Voltage Switchgear
The busbar room is arranged in the upper part of the cabinet. In the busbar room, the main busbars are connected together and run through the entire row of switch cabinets.
4. Switch room of GZS8 Interval Metal-Enclosed Switchgear,High Voltage Switchgear
A three-position load switch is installed in the switch room. The load switch uses sulfur hexafluoride gas as the insulating medium, and a gas pressure monitor with alarm device can be installed according to customer requirements.
5. Cable room of GZS8 Interval Metal-Enclosed Switchgear,High Voltage Switchgear
- The switch cabinet has ample cable compartment, which is mainly used for cable connection, so that single-core or three-core cables can be connected with the simplest unshielded cable head, and at the same time, ample space can also accommodate lightning arresters, current transformers, and lower grounding switches And other components.
- The cabinet door has an observation window and a safety interlock device.
- The bottom plate is equipped with a sealing cover and a cable clamp of appropriate size with a support frame.
- The bottom plate and door are removable, which is convenient for cable installation.
6. Operating mechanism, interlocking mechanism and low-voltage control room
The low-pressure chamber with interlock also functions as a control panel. The low-voltage room is equipped with a spring operating mechanism with a position indicator and a mechanical interlocking device. Auxiliary contacts, trip coils, emergency trip mechanisms, capacitive charged displays, key locks and electric operating devices can also be installed. At the same time, the low-voltage room The space can also be equipped with control circuits, measuring instruments and protective relays.
