Abstract
The utility model relates to an armored movable type metal enclosed switch cabinet comprising a cabinet body, a movable component, contact boxes and a valve mechanism. A breaker chamber, a bus chamber, a cable chamber and an instrument chamber are formed at the cabinet body; and a circuit breaker is arranged inside the breaker chamber. Contact boxes for forming conductive channels are arranged between the bus chamber and the breaker chamber and between the breaker chamber and the cable chamber; and the valve mechanism is arranged at stand columns at the two side surfaces of the cabinet body. In addition, the switch cabinet also includes a contact box installing plate that is fixedly installed at clamp plates and the stand columns; and the middle portion of the contact box installing plate is protruded to form an installing convex surface for contact box installation. On the basis of the arrangement, the provided switch cabinet with the advantages of simple structure as well as secure and reliable operation can meet a 65-KV power frequency voltage withstanding requirement and is suitable for application to a 35-KV rated voltage level.
Description
Technical field
The utility model relates to a kind of armored withdraw type metal enclosed switch cabinet, relates in particular to a kind of armored withdraw type metal enclosed switch cabinet of 35KV grade of rated voltage.
Background technology
The armored withdraw type ac metal closing switch gear of the 35kV grade of rated voltage of domestic production at present, its version all is to change from the mid-cabinet of the metal armouring of 10kV grade of rated voltage, though can satisfy the one minute 50kV power frequency withstand test that requires of IEC standard, but when system is 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 65kV industrial frequency withstand voltage and requires from the mid-cabinet of the metal armouring of 10kV grade of rated voltage.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, provide a kind of simple in structure, safe and reliable to operation, can satisfy the armored withdraw type metal enclosed switch cabinet requirement of 65KV industrial frequency withstand voltage and that be applicable to the 35KV grade of rated voltage.
For achieving the above object, the utility model adopts a kind of armored withdraw type metal enclosed switch cabinet, comprise cabinet, can remove parts, contact box and valve mechanism, described cabinet forms breaker chamber, bus-bar room, cable vault and control room, be provided with circuit breaker in the breaker chamber, between bus-bar room and the breaker chamber, be equipped with the contact box that is used to form conductive channel between breaker chamber and the cable vault, valve mechanism is arranged on the column of two sides of cabinet, armored withdraw type metal enclosed switch cabinet also comprises a contact box mounting panel, the contact box mounting panel is fixedly mounted on clamping plate and the column, protrudes to be formed with one for the installation convex surface that contact box is installed in the middle of the contact box mounting panel.
The utility model further arranges again, be formed with around the contact box mounting panel for the fixing installation convex surface of clamping plate, column, the installation convex surface in the middle of the contact box mounting panel is provided with the contact box installing hole.
The utility model further arranges again, described valve mechanism comprises guide plate, guide rod and valve, and guide plate is installed on the column, and guide rod is installed on the guide plate, valve is sleeved on the guide rod and constitutes flexible connection with guide rod, and described guide plate and guide rod are nonmetallic materials.
In sum, the beneficial effects of the utility model are: because the installation convex surface on the contact box mounting panel is away from the direction setting of circuit breaker, so just increased the distance between circuit breaker and the contact box installation convex surface, improved electric field between the two, the discharge breakdown phenomenon can not take place in the 65kV power frequency withstand test at one minute in the armored withdraw type metal enclosed switch cabinet that has guaranteed the 35KV grade of rated voltage, and is safe and reliable to operation and simple in structure.
