Abstract
The utility model relates to an upper pressure release type ring main unit, comprising a cabinet body, a cable room, a bus room and an instrument room, also comprising a cable room pressure release channel located at the rear side of the cabinet body and communicated with the cable room, the cable room pressure release channel and the bus room are isolated from each other by an isolation plate, and the pressure release opening of the cable room pressure release channel is located at the top of the cabinet body. The upper pressure release type ring main unit is mainly applied to power equipment set industry, and enables various functional units not to be mutually influenced in a failure or in an accident; the bus room and the cable room pressure release channel are isolated, thereby preventing accident extension; a high pressure gas can be released from the thinner position of a pressure release cover plate in the failure or in the accident; the nylon bolt of the rear portion of the pressure release cover plate falls off before that a front portion metal bolt falls off, and the pressure release gas flow is guided to the rear portion of the top portion of the cabinet body, thereby ensuring the human body safety of operation maintenance personnel.
Description
Technical field
The utility model relates to a kind of ring main unit, is specifically related to the upper pressure release type ring main unit of a kind of each functional unit independence, top pressure release.
Background technology
For guaranteeing that the ring main unit controller switching equipment is breaking down or the safety of operating personnel and ring main unit controller switching equipment during accident, each functional unit of ring network cabinet body designing requirement ring main unit all will have independently pressure relief device.And the pressure release direction of each functional unit pressure relief device of traditional ring main unit, be to the pressure release of cabinet rear lower, although existing this design can break down or makes cabinet internal pressure gas leakage during accident at ring main unit, guarantee device security, pressure release when but if operating personnel operate behind cabinet, life security that then can the serious harm operating personnel.Power department requires middle high-pressure distribution ring main unit series products for this reason, and each functional unit independently pressure release direction of pressure relief device all pushes up the rear portion pressure release to cabinet, to guarantee ring main unit controller switching equipment and operating personnel's safety.
Because special circuit breaker and the structure of ring main unit, ring main unit is divided into up and down two independently functional units by middle part mounting panel in the cabinet with ring main unit, so that lower functional units realizes comparatively difficulty of independently top pressure release.
The utility model content
Solve each functional unit independence pressure release passage pressure release direction of traditional ring main unit behind cabinet, the shortcoming that may cause the personal security accident, the utility model proposes a kind of upper pressure release type ring main unit, solve each functional unit independence pressure release passage of traditional ring main unit all to the pressure release of cabinet rear portion, may endanger the problem of operator safety.
The technical solution adopted in the utility model: a kind of upper pressure release type ring main unit, comprise cabinet, cable vault, bus-bar room, control room, also comprise and be positioned at cable vault's pressure release passage that the cabinet rear side is communicated with the cable vault, adopt the dividing plate isolation between described cable vault pressure release passage and the bus-bar room, the pressure relief opening of cable vault's pressure release passage is positioned at the cabinet top.
Described dividing plate adopts the aluminizing zine plate.
Circuit breaker drum pressure release passage cover plate is set on the described dividing plate.
Described cabinet top arranges pressure release cover plate on the bus-bar room.
The pressure relief opening place of described cable vault pressure release passage arranges pressure release cover plate in the cable vault.
On the described bus-bar room in pressure release cover plate and the cable vault front portion of pressure release cover plate fix by metal bolts and cabinet, the rear portion is fixed by nylon bolt and cabinet.
On described circuit breaker drum pressure release passage cover plate, the bus-bar room in pressure release cover plate, the cable vault pressure release cover plate adopt the galvanized sheet thinner than cabinet board to make.
The beneficial effects of the utility model: the utility model is mainly used in electric power complete set of equipments industry, each functional unit of middle high-pressure distribution ring main unit has independently top pressure relief device, is breaking down or the safety of operating personnel and ring main unit during accident to guarantee ring main unit; Break down or during accident each functional unit be independent of each other, bus-bar room and cable vault's pressure release passage separately, the Accident prevention extension; Breaking down or during accident, high pressure gas cognition is released than weakness from the pressure release cover plate, and the nylon bolt of decompression cover postlaminar part can come off prior to anterior metal bolts, makes the pressure release air-flow be drawn towards rear portion, cabinet top, thereby has guaranteed Operation and Maintenance personnel's life safety.
Description of drawings
Fig. 1 is the structural representation of ring main unit in the prior art;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is stereogram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further, understands to make things convenient for the technical staff.
Such as Fig. 2, shown in Figure 3, a kind of upper pressure release type ring main unit, comprise cabinet, cable vault 1, bus-bar room 2, control room 3, also comprise and be positioned at cable vault's pressure release passage 4 that the cabinet rear side is communicated with cable vault 1, adopt the isolation of aluminizing zine plate between cable vault's pressure release passage 4 and the bus-bar room 2, the pressure relief opening of cable vault's pressure release passage 4 is positioned at the cabinet top.
Circuit breaker drum pressure release passage cover plate 5 is set on the dividing plate.
The cabinet top arranges pressure release cover plate 6 on the bus-bar room.
The pressure relief opening place of cable vault's pressure release passage 4 arranges pressure release cover plate 7 in the cable vault.
On the bus-bar room in pressure release cover plate 6 and the cable vault front portion of pressure release cover plate 7 fix by metal bolts and cabinet, the rear portion is fixed by nylon bolt and cabinet.
On circuit breaker drum pressure release passage cover plate 5, the bus-bar room in pressure release cover plate 6, the cable vault pressure release cover plate 7 adopt the galvanized sheet thinner than cabinet board to make.
Break down or during accident each functional unit be independent of each other, bus-bar room 4 and cable vault's 2 pressure release passages separately, the Accident prevention extension.
Breaking down or during accident, gases at high pressure in the cable vault 1 release by cable vault's pressure release passage 4 drainages pressure release cover plate 7 from the cable vault at cabinet top, gases at high pressure in the bus-bar room 2 pressure release cover plate 6 from the bus-bar room releases, the gases at high pressure that the circuit breaker drum leaks out can release from circuit breaker drum pressure release cover plate 5 and enter cable vault's pressure release passage 4, then pressure release cover plate 7 releases from the cable vault, because each decompression cover prelaminar part all adopts metal bolts to fix, the rear portion adopts nylon bolt to fix, under the pressure of gases at high pressure, the nylon bolt of decompression cover postlaminar part can come off prior to anterior metal bolts, so the pressure release air-flow will be drawn towards rear portion, cabinet top, guaranteed Operation and Maintenance personnel's life safety.
The utility model describes by accompanying drawing, in the situation that does not break away from the utility model scope, can also carry out various conversion and be equal to replacement the utility model patent, therefore, the utility model patent is not limited to disclosed specific implementation process, and should comprise the whole embodiments that fall in the utility model Patent right requirement scope.
