Abstract
The utility model discloses a ring main unit with a pressure relief device. A pressure relief opening of the pressure relief device is positioned on the top side of a ring main unit body, and a pressure relief direction is upward. When the ring main unit has an internal arcing failure, injury to a field operator can be effectively prevented by the directional pressure relief of the pressure relief device.
Description
Technical field
The utility model relates to a kind of ring main unit, is specifically related to a kind of ring main unit that has pressure relief device.
Background technology
Ring main unit is a kind of very common electric equipment, belongs to a kind of of high-tension switch cabinet.Existing ring main unit is meant with the on-load switch to be the loading switch cabinet of main switch.It is that one group of high voltage switchgear is assemblied in the assembly unit compartment electric equipment of being formed in the steel sheet metal cabinet, and on-load switch has been adopted or by unit equipment that on-load switch and fuse constituted in its core.
Existing ring main unit is in actual application; In a single day arc fault occurs in the cabinet, cabinet gas inside pressure promotes suddenly, gas can impact all directions of cabinet; The external components such as cabinet door that cause cabinet are easily washed open, thereby injure the site operation personnel.Suddenly promote the danger that causes in order to cut down gas pressure, guarantee operating personnel's personal safety, the pressure relief devices of installing on ring main unit can make gas discharge from the pressure relief opening of pressure relief device rapidly more.
But on the market in the existing ring main unit part pressure relief device is not installed, though another part has been installed pressure relief device, because the pressure relief opening of pressure relief device all is positioned at the front side or the rear side of ring main unit cabinet.Though gas can be discharged through the front side of cabinet or the pressure relief opening of rear side in the cabinet that pressure rises sharply, the air venting direction is right against the people, and the cabinet door of cabinet front side or the shrouding of rear side are very likely washed open and injured the site operation personnel.
The utility model content:
In view of this, the purpose of the utility model provides a kind of in taking place during the arcing fault, thereby can not injure site operation personnel's ring main unit through the pressure relief device directional pressure venting.
For addressing the above problem, the technical scheme that the utility model provided is: a kind of ring main unit that has pressure relief device, and the pressure relief opening of said pressure relief device is positioned at the top side of cabinet, and the pressure release direction is upwards.
Preferably, said pressure relief device comprises cable vault's pressure relief device and bus-bar room pressure relief device.
Preferably, said cable vault pressure relief device is connected with ring main unit cabinet rear portion.
Preferably, said cable vault pressure relief device is connected through securing member with ring main unit cabinet rear portion.
Preferably, the pressure release passage of said cable vault pressure relief device comprises the pressure release passage group welding piece and is provided with the pressure release top cover of relief hole.
Preferably, said pressure release top cover mainly is connected through plastic screw with the pressure release passage group welding piece.
Preferably, said relief hole is the blinds hole.
Preferably, said bus-bar room pressure relief device comprises the cabinet top cover that is provided with perforate.
Preferably, said cabinet top cover mainly is connected through plastic screw with cabinet.
Preferably, said perforate is the blinds hole.
Compared with prior art, the utility model adopts the pressure release direction of pressure relief device to be set to direction upwards, when gas pressure rises sharply in the cabinet, and the gas release pressure that can make progress through the pressure relief opening of pressure relief device.Have the ring main unit that pressure relief opening is installed in cabinet front and back side now, when washing pressure relief device open in case take place gas to have little time pressure release, because the pressure release direction is right against the people, the pressure release top cover of the pressure relief opening that air-flow during pressure release or quilt are washed open will injure the operating personnel at scene.And behind employing the utility model, because pressure relief opening is positioned at the cabinet top, the air venting direction is not right against the people, even pressure relief device is washed open also and can not injured the site operation personnel during pressure release.
Description of drawings
Fig. 1 is the axonometric drawing of the utility model ring main unit;
Fig. 2 is the axonometric drawing of ring main unit cabinet shown in Figure 1 rear portion pressure relief device.
Embodiment
In order to make those skilled in the art understand the technical scheme of the utility model better, the utility model is done further to specify below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 1 and Fig. 2, ring main unit cabinet top is bus-bar room 1, and control room 2 is positioned at the front portion of bus-bar room.2 belows, control room are mechanism chamber 3, and bottom of cabinet bulk has cable vault 4.The pressure relief opening 8,9 of ring main unit pressure relief device all is positioned at the top side of cabinet, and the pressure release direction upwards.The ring main unit pressure relief device comprises cable vault's pressure relief device and bus-bar room pressure relief device.Cable vault's pressure relief device 5 is connected through securing member with ring main unit cabinet rear portion.The pressure release passage of cable vault's pressure relief device comprises pressure release passage group welding piece 6 and pressure release top cover 7.Pressure release top cover 7 mainly is connected through plastic screw 10 with pressure release passage group welding piece 6, and it is pressure relief opening 8 that the pressure release top cover is provided with relief hole.The bus-bar room pressure relief device comprises that the perforate on the ring main unit cabinet top cover is a pressure relief opening 9, and the cabinet top cover mainly is connected through plastic screw with cabinet.Said perforate or relief hole all can be the blinds holes.
When above-mentioned ring main unit arc fault occurred in use, the gas flow that the cabinet internal pressure rises sharply sprayed to the cabinet top through the guiding of pressure relief device.Because pressure relief opening is not right against the people, can not injured the site operation personnel even pressure relief device washes open also.
Only be the preferred implementation of the utility model below, should be pointed out that above-mentioned preferred implementation should not be regarded as the restriction to the utility model, the protection range of the utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in spirit that does not break away from the utility model and scope, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
