It is widely used in 11KV electric power distribution system. The switchgear meet the requirements of standard IEC62271-200,IEC62271-100 etc.

Convenient Installation

Its small volume & light weight make user to install & delivery it more conveniently and easy . It can be completed wiring schemes according to user’s need, also can choose the intelligent control units to realize intelligent controlling & operation. Standard design make this product to be the best choice of users.

Simple operation

Each switchgear has single line diagram(SLD) & analog displayer which can display inside parts. For operation, it has interlock board to guarantee the handle direction of rotation with correct operation. In order to avoid the operation in mistake, on the door, there has operation manual to supply & guarantee the simple & safe operation.

Structural Features

Its enclosure ,door & the upper chamber is spray processing. All cabinets have main grounding busbar which can connect near cabinet. All the metal parts, like grounding switch & interlocking parts are connected with grounding busbar. In order to ensure the continuity, between the parts which connected by screws ,the connection is used by copper braid. On the back of cabinet,there has pressure relief door to ensure the gas release from the back to avoid inner burning arc. Its upper board is fixed by screws. So it can be opened from outside to connect bus. Its upper auxiliary devices chamber can be installed with terminals and other parts. After heighten the small chamber, it can realize the relay protection. The load break switch & grounding switch adopts block type interlock. The grounding switch & door adopts coercive interlock .Following below steps ,it can realize automatic interlock: close the door, turn on the grounding switch and close the load break switch. This separately operation can avoid fault.

Safe operation of HXGN15-11 series switchgear

Its professional structure design to guarantee its operation safety.

The whole switchgear is divided into 5 insulation intervals.

The interlock structure is reliable, simple and convenient.
