A kind of fixed loop-network switch cabinet, there is airtight cabinet, cabinet internal the isolation the most successively by horizontal baffle is divided into bus-bar room, breaker chamber, disconnecting switch room and cable vault, and in the front side of cabinet equipped with low pressure control room, it is characterized in that: at bus-bar room, it is provided with pressure release passage between breaker chamber and disconnecting switch room and the back door of cabinet, wherein it is correspondingly provided with breaker chamber pressure relief plate and disconnecting switch room pressure relief plate between breaker chamber and disconnecting switch room and pressure release passage respectively, the lower end of pressure release passage is connected with cable vault, and above pressure release passage and bus-bar room, it is correspondingly provided with cable vault's pressure relief plate 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 present invention not only achieves the modularity of cabinet internal part and the miniaturization of cabinet, and prevents the impact on other compartment of the accident generation chamber, it is ensured that cabinet outworker's personal safety.
Description
Technical field
The present invention relates to a kind of high voltage power distributing cabinet, 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 big, cabinet structure is single, and lack safety prevention measure, so not only bad for cabinet internal high pressure bus, chopper and isolator operating mechanism and the installation of relevant low-voltage equipment and security isolation, safe operation to high voltage power distribution brings serious threat, and when occurring blast to be badly in need of pressure release inside cabinet, owing to lacking safety prevention measure, the high temperature and high pressure gas that blast produces is easy to parts of good performance to cabinet internal work and produces extreme shock, even personal safety is brought significant impact.
Summary of the invention
Present invention aim to solve current loop-network switch cabinet volume big, cabinet structure is single, and lack safety prevention measure, cause the safe operation of serious threat high voltage power distribution, the problem that even personal safety is brought significant impact, there is provided a kind of volume little for this, the internal each parts isolation of cabinet is good, and the fixed loop-network switch cabinet that security protection performance is high.
The concrete scheme of the present invention is: a kind of fixed loop-network switch cabinet, there is airtight cabinet, cabinet internal the isolation the most successively by horizontal baffle is divided into bus-bar room, breaker chamber, disconnecting switch room and cable vault, and in the front side of cabinet equipped with low pressure control room, it is characterized in that: at bus-bar room, it is provided with pressure release passage between breaker chamber and disconnecting switch room and the back door of cabinet, wherein it is correspondingly provided with breaker chamber pressure relief plate and disconnecting switch room pressure relief plate between breaker chamber and disconnecting switch room and pressure release passage respectively, the lower end of pressure release passage is connected with cable vault, and above pressure release passage and bus-bar room, it is connected externally to cable vault's pressure relief plate and the bus-bar room pressure relief plate led to cabinet when being correspondingly provided with pressure release;Described cable vault pressure relief plate and bus-bar room pressure relief plate are installed on cabinet top.
The lower end of heretofore described breaker chamber pressure relief plate and disconnecting switch room pressure relief plate is connected each via hinge means is fixing with the sidewall of pressure release passage.
Heretofore described hinge means is hinge.
The present invention has the advantage that compared with traditional loop-network switch cabinet
(1) present invention achieves primary circuit and the isolation of secondary circuit high-low pressure, the parts such as primary circuit median generatrix, chopper, disconnecting switch are carried out reasonably layout simultaneously, and isolation distributes among bus-bar room, breaker chamber, disconnecting switch room and cable vault successively, so not only ensure the safe operation of high voltage power distribution, and achieve the modularity of loop-network switch cabinet internal part and the miniaturization of cabinet；
(2) present invention greatly facilitates installation and the later maintenance of internal components；
(3) present invention passes through pressure release passage, achieve cabinet each function compartment internal in the independent pressure release that explosion time occurs, ensure that not interfereing with each other of accident generation chamber and other compartment, not only contribute to the parts that other service behaviour of portion in protection cabinet body is good, and prevent the significant threat that cabinet outworker's personal safety is brought that has an accident inside cabinet.
Accompanying drawing explanation
Fig. 1 is the side view of the present invention；
Fig. 2 is the isometric views (not comprising back door) of the present invention；
Fig. 3 be in the present invention each function compartment have an accident (blast) time, gas flow to schematic diagram.
In figure: 1 bus-bar room, 2 breaker chambers, 3 disconnecting switch rooms, 4 cable vaults, 5 low pressure control rooms, 6 back doors, 7 pressure release passages, 8 breaker chamber pressure relief plates, 9 disconnecting switch room pressure relief plates, 10 cable vault's pressure relief plates, 11 bus-bar room pressure relief plates, 12 cabinet tops, 13 hinge means.
Detailed description of the invention
See Fig. 1-2, the present invention has airtight cabinet, cabinet internal the isolation the most successively by horizontal baffle is divided into bus-bar room 1, breaker chamber 2, disconnecting switch room 3 and cable vault 4, and in the front side of cabinet equipped with low pressure control room 5, particularly, at bus-bar room 1, it is provided with pressure release passage 7 between the back door 6 of breaker chamber 2 and disconnecting switch room 3 and cabinet, wherein it is correspondingly provided with breaker chamber pressure relief plate 8 and disconnecting switch room pressure relief plate 9 between breaker chamber 2 and disconnecting switch room 3 and pressure release passage 7 respectively, 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, it is connected externally to cable vault's pressure relief plate 10 and the bus-bar room pressure relief plate 11 led to cabinet when being correspondingly provided with pressure release;Described cable vault pressure relief plate 10 and bus-bar room pressure relief plate 11 are installed on cabinet top 12.
Seeing Fig. 2, the lower end of breaker chamber pressure relief plate described in the present embodiment 8 and disconnecting switch room pressure relief plate 9 is connected each via hinge means 13 is fixing with the sidewall of pressure release passage 7, and wherein hinge means 13 is hinge.
See Fig. 3, when the parts generation explosion time installed in breaker chamber 2 or disconnecting switch room 3, breaker chamber pressure relief plate 8 or disconnecting 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 outside cabinet；In like manner, when the parts generation explosion time installed in bus-bar room 1 or cable vault 4, 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 is discharged outside cabinet, ensure that the balance of cabinet inner and outer air pressure, the most not only protect the parts that in cabinet, in other compartment, service behaviour is good, and prevent the significant threat that cabinet outworker's personal safety is brought that has an accident inside cabinet.
