Overview
Since the 1950s, the development of medium-voltage switchgear has gone through open type, box type, and metal-enclosed stages. In terms of meeting the functional use requirements of the equipment, there are no longer any problems, and the products have been serialized and used in a wide range of complete sets. Small size, maintenance-free, modular, safe and reliable environmentally friendly solid insulated ring network cabinets are developing rapidly, which can realize remote monitoring, control and management of the power distribution network, realizing network optimization, power safety, electric energy management, energy saving and consumption reduction requirements. At the same time, the system can be widely used in transportation, industry, hospitals, schools, construction, residential areas and applications such as written examinations and other intelligent electrical fields.
The HBN-12 energy-saving environmentally friendly fully insulated ring network cabinet fully introduces standard production equipment and manufacturing technology, realizes local production, greatly reduces manufacturing costs, and shortens the delivery period, facilitating after-sales service and use.

Product Structure
1. Flow meter
2. Microcomputer comprehensive protection device
3. Cable with live display
The cable head indicating sleeve is with live display, and three jacks under the indicating lamp can be used for secondary nuclear phase. The live display device is provided with a switch button, which effectively extends the service life.
4. Fault indicator
By detecting the current in the cable, when a short-circuit fault current or earth fault current appears, an alarm indication is given.
5. Observation window
Through this observation window, the opening and closing status of the earth switch and whether the isolating switch is closed or open can be seen.
6. Earth switch operating hole
By inserting the operating handle to drive the earth switch operating shaft, the earth switch can be opened and closed.
7. Main switch energy storage indicator
Observing the main switch energy storage indicator can grasp the energy storage status of the main switch operating mechanism.
8. Energy storage operation hole
By inserting the operating handle to drive the energy storage mechanism, the main switch operating mechanism is stored.
9. Energy storage operation interlocking device
The energy storage device has a hook locking plate to block the energy storage operation hole. Only by pulling the interlocking plate can the operating handle be inserted into the operating hole. If not operated, the hook can be pulled to prevent unauthorized personnel from operating by mistake.
10. Counter display
Indicates the accumulated opening and closing times of the main switch operating mechanism.
11. Electric door / local conversion switch
Through the far/local conversion switch, the conversion of the control mode between the local control and the back control of the equipment is realized.
12. Illumination button
Through the observation window, the switch of the control lighting lamp is pressed.
14. Mode display diagram
Indicates whether the main switch and earth switch are closed or open.
15. Pressure gauge
Displays the gas pressure value inside the gas box relative to the outside.
16. Isolating switch operating hole
By inserting the operating handle to drive the isolating switch operating shaft, the isolating switch can be opened and closed.
17. Isolating switch operating hole and earth switch operating hole interlocking device
The linked locking device blocks the earth switch operating hole or the isolating switch operating hole. Only by pulling the interlocking plate can the operating handle be inserted into the earth switch operating hole or the isolating switch operating hole. If not operated, the hook can be pulled to prevent unauthorized personnel from operating by mistake.
18. Main switch closing button
The main switch can be closed through this button.
19. Main switch opening button
The main switch can be opened through this button.
20. Cabinet door interlocking
The cable chamber door and the earth switch are interlocked. When a mechanical interlock is provided, the cable chamber door can only be opened when the earth switch is in the earthed closing position and the cabinet door interlock is pulled to the unlock position. When the cabinet door is opened, the related switch cannot be operated.
21. Electromagnetic observation window
