Description
Technical field
The utility model relates to a kind of high voltage power distributing cabinet, especially a kind of fixed loop-network switch cabinet.
Background technology
At present, high voltage power distributing cabinet is widely used in the power distribution station at different levels of town and country.But, loop-network switch cabinet volume in existing high voltage power distributing cabinet is large, cabinet structure is single, and lack safety prevention measure, like this not only bad for cabinet internal high pressure bus, the installation of circuit breaker and isolator operating mechanism and relevant low-voltage equipment and Secure isolation, serious threat is brought to the safe operation of high voltage power distribution, and to blast when being badly in need of pressure release in cabinet inside, owing to lacking safety prevention measure, the high temperature and high pressure gas that blast produces is easy to produce extreme shock to cabinet internal work parts of good performance, even significant impact is brought to personal safety.
Summary of the invention
The purpose of this utility model is exactly that will to solve current loop-network switch cabinet volume large, cabinet structure is single, and lack safety prevention measure, cause the safe operation of serious threat high voltage power distribution, even personal safety is brought to the problem of significant impact, there is provided a kind of volume little, the inner each parts isolation of cabinet is good for this reason, and the fixed loop-network switch cabinet that security protection performance is high.
Concrete scheme of the present utility model is: a kind of fixed loop-network switch cabinet, there is airtight cabinet, cabinet inner the isolation successively from top to bottom by horizontal baffle is divided into bus-bar room, breaker chamber, isolating switch room and cable vault, and in the front side of cabinet, low pressure control room is housed, it is characterized in that: at bus-bar room, breaker chamber and be provided with pressure release passage between isolating switch room and the back door of cabinet, wherein breaker chamber and isolating switch room are provided with breaker chamber pressure relief plate and isolating switch room pressure relief plate with corresponding respectively between pressure release passage, the lower end of pressure release passage is connected with cable vault, and above pressure release passage and bus-bar room, cable vault's pressure relief plate that correspondence is connected with cabinet outside when being provided with pressure release and bus-bar room pressure relief plate, described cable vault pressure relief plate and bus-bar room pressure relief plate are installed on cabinet top.
The pressure relief plate of breaker chamber described in the utility model is fixedly connected with the sidewall of pressure release passage each via hinge means with the lower end of isolating switch room pressure relief plate.
Hinge means described in the utility model is hinge.
The utility model has the following advantages compared with traditional loop-network switch cabinet:
(1) the utility model achieves the isolation of primary circuit and secondary circuit high-low pressure, reasonably layout is carried out to parts such as primary circuit median generatrix, circuit breaker, isolating switches simultaneously, and isolation is distributed among bus-bar room, breaker chamber, isolating switch room and cable vault successively, not only ensure the safe operation of high voltage power distribution like this, and achieve the modularization of loop-network switch cabinet internal part and the miniaturization of cabinet;
(2) the utility model greatly facilitates installation and the later maintenance of internal components;
(3) the utility model passes through pressure release passage, achieve the independent pressure release of cabinet each function compartment inner when blasting, ensure that not interfereing with each other of accident generation chamber and other compartment, not only be conducive to protecting the good parts of cabinet other service behaviour inner, and prevent the inner significant threat that cabinet outworker personal safety is brought that has an accident of cabinet.
Accompanying drawing explanation
Fig. 1 is end view of the present utility model;
Fig. 2 is isometric views of the present utility model (not comprising back door);
Fig. 3 be in the utility model each function compartment have an accident (blast) time, gas flow to schematic diagram.
In figure: 1-bus-bar room, 2-breaker chamber, 3-isolating switch room, 4-cable vault, 5-low pressure control room, 6-back door, 7-pressure release passage, 8-breaker chamber pressure relief plate, 9-isolating switch room pressure relief plate, 10-cable vault pressure relief plate, 11-bus-bar room pressure relief plate, 12-cabinet top, 13-hinge means.
Embodiment
See Fig. 1-2, the utility model has airtight cabinet, cabinet inner the isolation successively from top to bottom by horizontal baffle is divided into bus-bar room 1, breaker chamber 2, isolating switch room 3 and cable vault 4, and in the front side of cabinet, low pressure control room 5 is housed, particularly, at bus-bar room 1, pressure release passage 7 is provided with between the back door 6 of breaker chamber 2 and isolating switch room 3 and cabinet, wherein breaker chamber 2 and correspondingly respectively between isolating switch room 3 with pressure release passage 7 be provided with breaker chamber pressure relief plate 8 and isolating switch room pressure relief plate 9, the lower end of pressure release passage 7 is connected with cable vault 4, and above pressure release passage 7 and bus-bar room 1, cable vault's pressure relief plate 10 that correspondence is connected with cabinet outside when being provided with pressure release and bus-bar room pressure relief plate 11, described cable vault pressure relief plate 10 and bus-bar room pressure relief plate 11 are installed on cabinet top 12.
See Fig. 2, the pressure relief plate of breaker chamber described in the present embodiment 8 is fixedly connected with each via the sidewall of hinge means 13 with pressure release passage 7 with the lower end of isolating switch room pressure relief plate 9, and wherein hinge means 13 is hinge.
See Fig. 3, when the parts installed in breaker chamber 2 or isolating switch room 3 are blasted, breaker chamber pressure relief plate 8 or isolating switch room pressure relief plate 9 are directly washed open by the gases at high pressure that blast produces, and wash cable vault's pressure relief plate 10 open along pressure release passage 7, thus discharge cabinet outside; In like manner, when the parts installed in bus-bar room 1 or cable vault 4 are blasted, the gases at high pressure correspondence that blast produces washes bus-bar room pressure relief plate 11 open or cable vault's pressure relief plate 10 discharges cabinet outside, thus ensure that the balance of cabinet inner and outer air pressure, so not only protect the parts that in cabinet, in other compartment, service behaviour is good, and prevent the inner significant threat that cabinet outworker personal safety is brought that has an accident of cabinet.
