Abstract
A novel 35 kV switch cabinet provided by the utility model comprises a handcart chamber, a bus chamber, a cable chamber and a relay chamber, and is characterized in that the bus chamber is located inside the cable chamber, the handcart chamber is connected with the cable chamber and the bus chamber via contact boxes, and the relay chamber is adjacent to the handcart chamber; the bus chamber, the cable chamber and the handcart chamber are all connected with a pressure relief device, and pressure relief holes are arranged on a clapboard between the bus chamber and the cable chamber. According to the utility model, the bus chamber, the cable chamber and the handcart chamber are all connected with the pressure relief device, so that the air pressure in the cabinet can be reduced effectively, and a high air pressure danger caused by a fault can be prevented; the pressure relief holes are arranged on the clapboard between the bus chamber and the cable chamber, so that the air pressure balance in the bus chamber and the cable chamber can be guaranteed, and the danger caused by the failure of a pressure relief cover plate can be prevented.
Description
Technical field
The utility model relates to high pressure assembled electric equipment field, relates in particular to a kind of novel 35kV switch cubicle.
Background technology
For improving power supply reliability, guarantee that the user can obtain power supply by both direction, power supply network connects into annular usually.This mode is referred to as ring network power supply.In urban distribution network, the application of ring network power supply is more and more extensive at present, as the ring network power supply terminal system, also just seems even more important.
Need to use switchgear assembly and control appliance when switch cubicle is ring network power supply, and be applicable to need have certain distance just not interfere with each other and guarantee electrical safety between the bus of high-tension switch cubicle.Because most of chambers in switch cubicle all need airtight work, when switch cubicle broke down, inner gases at high pressure usually produced immeasurable loss and threat because gather too much to equipment and personnel.Wherein, cable chamber and the bus-bar room in switch cubicle particularly, the consequence that causes is often more serious.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel 35kV switch cubicle, and effective conditioning equipment air pressure inside reduces fault and brings that Keep Clear-High Voltage.
The utility model is achieved through the following technical solutions:
A kind of novel 35kV switch cubicle, comprise handcart chamber, bus-bar room, cable vault and relay bungalow, and described bus-bar room is positioned at inside, cable vault; Between described handcart chamber and cable vault, be connected by contact box between handcart chamber and bus-bar room; The setting adjacent with the handcart chamber of described relay bungalow; Described bus-bar room, cable vault and handcart chamber all are connected with pressure relief device; Dividing plate between described bus-bar room and described cable vault is provided with relief hole.
Above-mentioned novel 35kV switch cubicle, described pressure relief device are the pressure release cover plate that is arranged at the switch cubicle top, and described pressure release cover plate has at least a side to use the securing member of plastics quality to fix.
Be provided with metal dampers before above-mentioned novel 35kV switch cubicle, described contact box.
Above-mentioned novel 35kV switch cubicle, also be provided with the insulating sleeve that extends to the switch cubicle outside in described bus-bar room.
The beneficial effects of the utility model are:
1, handcart chamber, cable vault and bus-bar room all are connected with pressure relief device, can effectively reduce the cabinet internal gas pressure, prevent the hyperbar danger that fault is brought;
2, the dividing plate between cable vault and bus-bar room is provided with relief hole, guarantees the air pressure balance in bus-bar room and cable vault, prevents the danger that some pressure release cover plate faults cause.
Description of drawings
Fig. 1 is novel 35KV switch cabinet structure schematic diagram of the present utility model.
In above-mentioned accompanying drawing, 1, cable vault; 2, bus-bar room; 3, relay bungalow; 4, handcart chamber; 5, contact box; 6, pressure release cover plate; 7, relief hole.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model provides a kind of novel 35kV switch cubicle, comprises handcart chamber 4, bus-bar room 2, cable vault 1 and relay bungalow 3, and bus-bar room 2 is positioned at 1 inside, cable vault; Between handcart chamber 4 and cable vault 1, be connected by contact box 5 between handcart chamber 4 and bus-bar room 2; Handcart chamber 2 is used for handcart is installed, and passes through respectively the interior cable in the interior contact stube cable chamber of different contact box 51 and the bus in bus-bar room 2 on handcart, thereby can realize the control function of handcart.Be provided with metal dampers before contact box 5, can realize the protection to contact, reduce failure rate.
Relay bungalow 3 setting adjacent with handcart chamber 4; Be used for installing relay, terminal, instrument and monitoring terminal and the simple and easy control terminals such as little bus and auxiliary switch in relay bungalow 3, to the ease of Use of whole switch cubicle.
Also establish the insulating sleeve that extends to the switch cubicle outside in bus-bar room 2.Main bus bar causes another switch cubicle from a switch cubicle, by branch bar and contact box, fixes, and when passing through adjacent cabinet dividing plate, bus is insulated sleeve pipe and fixes.While if Internal faults arc occurring, can restriction accident spread to adjacent cabinet, avoid a switch cubicle to break down and rear other equipment exerted an influence, Accident prevention enlarges, and plays the effect of the mechanical strength that ensures bus.
Bus-bar room 2, cable vault 1 and handcart chamber 4 all are connected with pressure relief device; Pressure relief device is the pressure release cover plate that is arranged at the switch cubicle top, described pressure release cover plate has at least a side to use the securing member of plastics quality to fix, one end of the pressure release cover plate in the present embodiment is fastening with metal bolts, the other end is fixed with plastic bolt, when breaking down in cabinet, under inner gases at high pressure effect, plastic bolt is destroyed, the pressure release cover plate easily is rushed to open, and release pressure, to guarantee operating personnel's safety.Dividing plate between bus-bar room 2 and cable vault 1 is provided with relief hole 7.Relief hole 7 is linked up bus-bar room 2 and the air in cable vault 1, in the time of can effectively preventing among bus-bar room 2 and cable vault 1 a certain chamber fault, and the highly dangerous of the inner excessive formation of air pressure difference.Can prevent also simultaneously that the pressure release cover plate fault corresponding with bus-bar room 2/ cable vault 1 from causing the danger that pressure release has some setbacks and causes.
Above-described embodiment is only for the utility model creation example clearly is described, and not the utility model is created the restriction of embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description, need not also can't give all execution modes exhaustive here.And the apparent variation of being amplified out thus or change still are among the protection range of the utility model creation claim.
