Abstract
The utility model provides indoor middling pressure metal-clad air insulation switch equipment, comprising a low-pressure chamber, a bus-bar room, a breaker chamber, a cable chamber, an integrated main pressure relief channel and an integrated secondary pressure relief channel. The breaker chamber and the cable chamber are horizontally arranged side by side at the front portion of a switch cabinet; the bus-bar room is next to the breaker chamber and the cable chamber and is arranged at the back portion of switch cabinet; the low-pressure chamber is vertically arranged over the breaker chamber and the cable chamber; the integrated main pressure relief channel is next to the back portion of the low-pressure chamber; and the integrated secondary pressure relief channel is next to the lower portion of the bus-bar room. According to the utility model, the length of a main loop is minimized, the application amount of copper is minimized, cost is reduced, compact compartment arrangement reduces the volume of the switch cabinet, the design of double pressure relief channels enables fast release of high pressure gas generated by an internal electric arc fault, and natural and continuous flowing air is generated through a chimney effect to take away heat in the cabinet.
Description
Technical field
The utility model belongs to the power product technical field, is specifically related to a kind of indoor medium voltage air insulated switch equipment that is applied to.
Background technology
Existing indoor medium voltage metal armoured air insulation switch cubicle, compartment is arranged, such as disclosed among the Chinese patent CN2355478Y, referring to Fig. 1, this air insulation switch cubicle is comprised of fixing cabinet and removable handcart, cabinet adopts the assembling of double-bending steel plate and bolt to form and is separated into bus-bar room by metal partion (metp), breaker chamber, cable vault and low-pressure chamber, pressure releasing plate is arranged at the top, detachable metal partion (metp) is arranged between breaker chamber and bus-bar room and between breaker chamber and cable vault, main bus bar is comprised of the D shape busbar of cover by the pyrocondensation insulating case, and the joint is provided with insulating cover.
As mentioned above, the problem that this switch cubicle exists is: major loop is partially long, need branch's busbar (, the use amount of copper is larger; Can't form the circulation of air of nature inside and outside the cabinet, dispel the heat relatively poor, bury potential safety hazard; In addition, need the extra discharge channel of installing, increased the volume of switch cubicle, be unfavorable for fitting operation and maintenance.
The utility model content
The purpose of this utility model is to provide a kind of structure more reasonably to be applied to the indoor medium voltage air insulated switch equipment, and it comprises low-pressure chamber, bus-bar room, breaker chamber and cable vault.Insulated switching installation of the present utility model also comprises integrated form master discharge channel and integrated form time discharge channel.
According to most preferred embodiment of the present utility model, breaker chamber and cable vault's horizontal direction are arranged side by side at the front portion of switch cubicle; Bus-bar room is close to the rear portion that breaker chamber and cable vault are located at switch cubicle; The low-pressure chamber vertical direction is arranged in the top of breaker chamber and cable vault.
According to most preferred embodiment of the present utility model, integrated form master discharge channel is close to the rear portion that is arranged in low-pressure chamber; Integrated form time discharge channel is close to the bottom that is located at bus-bar room.
According to most preferred embodiment of the present utility model, the three-phase main bus bar is sequentially arranged in the bus-bar room from top to bottom; One end of the circuit breaker in the breaker chamber directly with the bus-bar room grafting, the other end is by the cable bond in isolating switch and the cable vault, next door.
Discharge channel that the utility model is integrated, the design of two discharge channel so that the gases at high pressure that produce because of the internal arc fault be released quickly; Form moving air that nature continues by stack effect and take away caloric value in the cabinet.Structural arrangement of the present utility model is compared with existing switch cubicle, has greatly reduced the length of major loop, thereby has reduced the use amount of copper, has reduced cost.Compact compartment is arranged the volume that has dwindled switch cubicle.In addition, the compartment of hommization arranges so that installation operates, and safeguards convenient.
