Abstract
The utility model relates to a switch cabinet accessory, in particular to a safety protection device for a movable switch cabinet. The safety protection device for the movable switch cabinet comprises a cabinet body and a cabinet door matched with the cabinet body. A convex or concave protection plate is mounted along the periphery of the frame of the cabinet body and the matched convex or concave protection plate is mounted along the periphery of the inner side of the cabinet door. The safety protection device for the movable switch cabinet provides a labyrinth structure which can effectively strengthen the strength of the cabinet door, increase the protection level of the cabinet door, effectively limit the release of energy from the front surface of the cabinet body when arcing fault occurs to the inside of the cabinet body, provide a safe environment for operators and can improve the aesthetic properties of the cabinet door.
Description
Technical field
The utility model relates to a kind of switch cubicle annex, relates in particular to a kind of safety device of switch cubicle.
Background technology
10kV Medium voltage switch or circuit breaker field in the electric power system is popular in the market KYN28-12 type intermediate switchgear cabinet, the fixed switch cubicle of XGN2-12 and the several types of the fixed switch cubicle of New X GN-12, though the cabinet door degree of protection of these a few class cabinet types can reach IP4X, aspect dustproof, performance is preferably arranged, but also there is wretched insufficiency aspect the anti-arcing, when the arcing fault takes place in inside, energy is easy to discharge from the space between door-plate and the framework, and the safety to the people has caused very big threat like this.
The utility model content
Technique effect of the present utility model can overcome above-mentioned defective, and a kind of withdraw-type switch cabinet safety device is provided, and it can prevent effectively that operating personnel from coming to harm in the cabinet front.
For achieving the above object, the utility model adopts following technical scheme: it comprises cabinet and the cabinet door that cooperates with it, and the framework of cabinet is along installing convex or spill protective plate all around, and the inboard of cabinet door is along supporting with it spill or convex protective plate are installed all around.
The spill protective plate is U type or V-structure.When around the framework edge of cabinet the convex protective plate being installed, the inboard of Dui Ying cabinet door when closing cabinet door makes stiffener cabinet body frame on be embedded in cabinet door stiffener in the middle of along supporting with it spill protective plate is installed all around with it; When the framework of cabinet along around when the spill protective plate is installed, with it the inboard of Dui Ying cabinet door along around the supporting with it convex protective plate of installation, cabinet door stiffener is embedded in the middle of the stiffener on the cabinet body frame.Above-mentioned two kinds of situations have all formed a U type or V-type passage, and when breaking down in cabinet inside, energy can not directly discharge the space between door-plate and framework, must could outwards release energy by this U type or V-type passage.Compare with the intensity of this structure, it is insignificant that the intensity of release of pressure plate just seems.So just the strength weak of cabinet point is concentrated on the release of pressure plate, promptly fault release of pressure break-through point is preferentially selected in the release of pressure plate, and the release of pressure direction of release of pressure plate is arranged on the cabinet top more, and operating personnel just are difficult for having come to harm in the cabinet front like this.Can certainly adopt two spill protective plates to be used in combination.
The projection of convex protective plate and spill protective plate adopts double-decker, can strengthen the intensity of protective plate like this.
The utility model provides a kind of can effectively strengthen cabinet door intensity, improve cabinet door degree of protection, can effectively limit energy when the arcing fault takes place and positively discharge, a security context be provided and can increase the labyrinth structure of cabinet door aesthetic property for operating personnel from cabinet in that cabinet is inner.
The utility model can effectively strengthen the obstruction effect of arcing explosion time door-plate to energy, has so just improved the positive intensity of cabinet, make concentration of energy during fault to the weakest link-release of pressure plate of cabinet, thereby safe release reduces the harm to human body.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is that spill combines schematic diagram with the convex protective plate.
Embodiment
This device comprises cabinet 1 and the cabinet door that cooperates with it, and the framework of cabinet 1 is along installing convex protective plate 2 and spill protective plate 3 all around, and the inboard of cabinet door is along supporting with it spill protective plate 3 and convex protective plate 2 are installed all around.
Spill protective plate 3 is U type structure, and the projection of convex protective plate 2 and spill protective plate 3 adopts double-decker, and when device fails, energy discharges along spill protective plate 3 directions of U type structure.
Claims (3)
1. a withdraw-type switch cabinet safety device comprises cabinet and the cabinet door that cooperates with it, and the framework that it is characterized in that cabinet is along installing convex or spill protective plate all around, and the inboard of cabinet door is along supporting with it spill or convex protective plate are installed all around.
2. withdraw-type switch cabinet safety device according to claim 1 is characterized in that the spill protective plate is U type or V-structure.
3. withdraw-type switch cabinet safety device according to claim 1 is characterized in that the projection of convex protective plate and spill protective plate adopts double-decker.
