Description
Technical field
The utility model relates to a kind of armored withdraw type metal enclosed switchgear, is used for receiving and distributes electric energy and circuit is protected and detected, and belongs to the indoor distribution technical field.
Background technology
The indoor ac metal closing switch gear of armored withdraw type of domestic production at present; Its version all is directly to change from the mid-cabinet of the metal armouring of 10kV grade of rated voltage; Promptly bear one minute 50kV power frequency withstand test though can satisfy the IEC standard-required; But when system is an isolated neutral or during through grounding through arc; National standard requires switchgear can bear one minute 65kV power frequency withstand test, and above-mentioned directly changes and the switchgear that comes can not satisfy the 95kV-110kV industrial frequency withstand voltage and requires from the mid-cabinet of the metal armouring of 10kV grade of rated voltage.
The utility model content
The above-mentioned background technical problem that be to solve, the utility model provide a kind of simple in structure, safe and reliable to operation, can satisfy the requirement of 95kV-110kV industrial frequency withstand voltage and armored withdraw type metal enclosed switchgear that be applicable to the 40.5kV grade of rated voltage.
For realizing above-mentioned purpose; A kind of armored withdraw type metal enclosed switchgear that the utility model provides; Comprise cabinet, said cabinet is divided into into handcart chamber, bus-bar room, cable vault and control room, is to separate through clamping plate between described handcart chamber, bus-bar room, cable vault and the control room; Indoor circuit breaker and the handcart of being provided with of described handcart; Be provided with the contact box that is used to form conductive channel between bus-bar room and the handcart chamber and between handcart chamber and the cable vault, the column of described inner side surface of cabinet is provided with the valve mechanism that has been used for safe buffer action, also is provided with a contact box mounting panel on the described column; Said contact box mounting panel is fixed on said clamping plate and the column, in the centre of contact box mounting panel to be formed with away from the direction protrusion of circuit breaker one be used to install said contact box the installation convex surface.
Be used for and clamping plate, the fixing mounting lug of column being formed with all around of said contact box mounting panel, and on the installation convex surface in the middle of the said contact box mounting panel, offer a box installing hole.
Described contact box near the contact box end face of circuit breaker direction between the described installation convex surface apart from M greater than said installation convex surface to away from circuit breaker direction protrusion apart from N.
The beneficial effect of the utility model: because the installation convex surface on the contact box mounting panel is to the direction protrusion away from circuit breaker; Increased like this circuit breaker straight with contact box installation convex surface between distance; Improved electric field between the two; The discharge breakdown phenomenon can not take place in the 95kV-110kV power frequency withstand test at one minute in the armored withdraw type metal enclosed switchgear that has guaranteed the 40.5kV grade of rated voltage, and is safe and reliable to operation and simple in structure.
