Description
Technical field
The utility model is related to the technical field of high-tension switch cabinet, more particularly to high-tension switch cabinet security protection
The technical field of device.
Background technology
High-tension switch cabinet refer to be used for power system generate electricity, transmission of electricity, distribution, and electric energy conversion and consumption in rise break-make,
The power distribution equipment of the effect such as control or protection, by the voltage that high-tension switch cabinet is controlled is very high, when its internal electrical equipment
When generation short circuit or other fortuitous events, can suddenly it be raised by the electric current of electrical equipment, while being risen sharply with temperature so that high
The electrical equipment compressed switch in cabinet easily explodes, and when occurring explosion time, can produce instantaneous high pressure air-flow in high-tension switch cabinet,
Traditional high-tension switch cabinet is typically not provided with pressure release protecting structure so that the high pressure draught that explosion time is produced can not obtain effective wink
When discharge, high pressure draught will blow cabinet door, while the electrical equipment fragment blown up can fly out, around high-tension switch cabinet
Personnel cause serious injury, there is great potential safety hazard.
Utility model content
The purpose of this utility model is exactly to provide a kind of safe and reliable in order to solve above-mentioned deficiency, can progressively be let out
Pressure, the blast resistance construction of high-tension switch cabinet for preventing the high pressure draught that explosion time is produced from being damaged to operating personnel.
The technical solution that in order to solve the above-mentioned technical problem the utility model uses is as follows：
The blast resistance construction of high-tension switch cabinet, it mainly includes cabinet, cabinet door, main cover plate, auxiliary coverplate and plastic bolt, institute
State cabinet door to be movably arranged on cabinet, form hole is offered in the cabinet door, transparent panel is installed at the form hole, it is saturating at this
It is provided with cabinet on the inside of isotropic disk in the middle part of protection network, the plastic bolt and offers groove, the plastic bolt is divided into first
Plastic bolt and the second plastic bolt, offer the first pressure relief opening at the top of cabinet, and the main cover plate lid is put first to be let out at this
Press at mouth, a lateral edges of main cover plate are hinged by the first hinge and cabinet, and remaining edge is arranged on by the first plastic bolt
On cabinet, the second pressure relief opening is offered on main cover plate, the auxiliary coverplate lid is put at second pressure relief opening, a side of auxiliary coverplate
Edge is hinged by the second hinge with main cover plate, and remaining edge is arranged on main cover plate by the second plastic bolt, is opened on auxiliary coverplate
Provided with mesh.
On first hinge is located at the top of the cabinet of cabinet door side, second hinge is located at close to the first hinge
On the main cover plate of side.
The transparent panel is plastic plate.
The beneficial effect that the utility model can be reached using above-mentioned technical solution is：When the electrical equipment in cabinet
Generation explosion time, due to offering groove, therefore the instantaneous high pressure air-flow that plastic bolt is produced in explosion time in the middle part of plastic bolt
Percussion under be broken at first, auxiliary coverplate or main cover plate is rushed to open, instantaneous high pressure air-flow discharged at the top of the cabinet,
Prevent instantaneous high pressure air-flow blows cabinet door from hurting sb.'s feelings.Because the first hinge and the second hinge are installed in close to the side of cabinet door side
On position so that instantaneous high pressure air-flow can be flowed towards the diagonal upward direction at cabinet door rear, prevent high pressure draught in front of cabinet door
Personnel damage.When explosion happens, the second plastic bolt of fixed auxiliary coverplate can be first broken, the first plastic bolt
Then it is broken, auxiliary coverplate is first rushed to open, high pressure draught is obtained a part of release from the second pressure relief opening in advance, to prevent
The pressure of instantaneous high pressure air-flow is crossed senior general's main cover plate and blown up, and main cover plate is rushed to open after auxiliary coverplate, by residual high pressure air-flow from
First pressure relief opening is released, and the pressure energy for producing explosion time, which is accessed, progressively to be discharged, and substantially increases security protection effect；
Meanwhile, protection network is installed on the inside of transparent panel, the electrical equipment fragment barrier produced can will be exploded in cabinet, prevent broken
Piece, which flies out, hurts sb.'s feelings.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 overlooking the structure diagram；
Fig. 3 is the structural representation of plastic bolt.
Embodiment
As shown in Fig. 1 and Fig. 2, the blast resistance construction of high-tension switch cabinet, it mainly include cabinet 1, cabinet door 2, main cover plate 3,
Auxiliary coverplate 4 and plastic bolt 5, the cabinet door 2 are movably arranged on cabinet 1, are offered form hole 6 in the cabinet door 2, are regarded at this
Transparent panel 7 is installed, the transparent panel 7 is plastic plate at fenestra 6, facilitates operating personnel to observe the situation inside cabinet 1, transparent
Protection network 8 is installed on the cabinet 1 of the inner side of plate 7, when explosion time occurs for the electrical equipment in cabinet 1, the protection network 8 will can explode
The fragment of generation is obstructed in cabinet 1, is prevented from flying out and is hurted sb.'s feelings.As shown in Figure 3, the middle part of the plastic bolt 5 offers groove
