The RSS-12Pro adopts three-phase split design, its overall dimensions meet the requirements of the national grid standard, and the surface of the insulator adopts the metallization coating process.
RSS-12Pro is a new switchgear facing the future, which has the characteristics of self-diagnosis, maintenance free, low temperature resistance, miniaturization, flexible splicing, green and environmental protection.
All conductive parts in the switch are fixed and sealed in solid insulating materials.
The main switch adopts vacuum arc extinguishing, and the disconnector adopts three position structure.
The adjacent switchgears are connected by solid insulated bus.
The secondary circuit adopts integrated control technology and supports data transmission function.

Adopted fully insulated and enclosed top expansion bus system, convenient for installation.
1.The cable compartment can only be opened when the feeder has been isolated or grounded.
2.The bushing complies with DIN EN 50181 standard and be connected with M16 bolts.
3.The integrated CT is located at the casing side, which is convenient for cable installation and is not affected by external forces.
4.The height from the casing installation place to the ground need to be more than 650mm.
In case of internal arcing fault, the special pressure relief device installed at the lower part of the body will automatically start for pressure relief.
1.The circuit breaker adopts a precise transmission mechanism with reclosing function. The output track of the isolation mechanism is sinusoidal to ensure that the closing and opening positions are accurate. The mechanism room and the main circuit are fully sealed. The secondary control circuit is connected with a sealed plug structure. The switch can be immersed in water for more than 96 hours, completely avoiding corrosion of the mechanism caused by external water vapor or pollution, failure to open and close, mis-operation of the control circuit and other failures, which may lead to a skip trip, Finally, a large area of power failure was caused.
1.The disconnector is of direct action type and equipped with spring finger contact structure, with small contact resistance, low temperature rise and large current carrying capacity, so as to ensure that any switch can meet 25kA/4s short-time withstand current.
1.Independent compartment structure is adopted between phases to avoid explosion accidents caused by interphase short circuit. The primary conductor is of circular or spherical structure and is equipped with high-voltage shielding outside. The surface of insulating parts is coated with metal and grounded reliably to ensure that the high-voltage electric field is evenly distributed and that external pollution will not have any impact on the insulation system.
1.The analog bus panel is clear and easy to operate.
2.The main switch is designed with a button for easy operation. The button structure is made of zinc alloy to avoid aging and failure.
3.The operation hole is designed with an anti misoperation cover, which can be padlocked.
4.Two independent operation holes are used for isolating and grounding switches.
5.The grounding switch equipped with a "voltage locking device" to prevent the grounding switch mis-closing when electrified.
