Abstract
The utility model relates to a miniature ring main unit, which comprises a ring main unit body, an upper door panel and a lower door panel arranged at the front end of the ring main unit body, the ring main unit body is divided into a secondary control chamber, a bus chamber, a breaker room and a cable room from top to down, an insulation switch, a breaker, a current transformer and an electroscope, and a flexible pipe interlock is provided between the insulation switch and the breaker. The miniature ring main unit has the advantages that the structure is compact and reasonable, the size of the ring main unit is greatly reduced, the insulation switch operating mechanism problem is overcome, an intermediate connecting rod is cancelled, and the interlock of the breaker and the insulation switch is more stable. The miniature ring unit can solves the disadvantages of large land occupation of the ring main unit, inconvenient installation and unstable function.
Description
Technical field
The utility model relates to a kind of small-sized ring main unit.
Background technology
Along with China's town and country development electric network reconstruction, ring main unit is proposed higher requirement, rare at urban land resource especially, the little characteristics of electricity room floor space, controller switching equipment is to saving land, economize on electricity, energy-conservation, miniaturization, automatically aspect development is at present in the ring main unit technology, huger (the wide 1000mm of ring main unit structure, dark 1100mm, high 2300mm) cabinet employing Type of Welding, bulky, floor space is big, cabinet adopts isolating switch and circuit breaker combination, and isolator operation adopts intermediate connecting rod, and extremely inconvenience is installed, isolating switch and circuit breaker interlocking are installed inconvenient, unstable properties, result of use is poor, and this kind equipment far can not satisfy the modern power network requirement.
Summary of the invention
It is little that the technical problems to be solved in the utility model provides a kind of volume, and the unfailing performance height is installed simple and conveniently, and isolator operating mechanism and circuit breaker interlocking is reliable, has handling safety, small-sized ring main unit easy to maintenance.
For solving technique scheme, the utility model adopts following technical scheme:
A kind of small-sized ring main unit, comprise cabinet, and be installed in the last door-plate of cabinet front end and following door-plate, described cabinet is divided into secondary control room, bus-bar room, breaker chamber and cable vault from top to bottom, described cabinet inside is equipped with isolating switch, circuit breaker, current transformer, the electroscopic device that connects by copper conductor successively, is provided with the flexible pipe interlocking between described isolating switch and circuit breaker.
As optimized technical scheme; described isolating switch form, instrument, Microcomputer Protection, the control button that the isolating switch position is installed on the door-plate of going up; on the described down door-plate isolating switch panel and circuit breaker panel are installed, and are installed in the described door-plate down and can prevent the charged electromagnetic lock of opening cabinet.
As optimized technical scheme, also be provided with cable vault's form on the described following door-plate, described secondary control room, bus-bar room, breaker chamber and cable vault adopt the SMC insulating material to separate successively, and described upper and lower door-plate all adopts cold drawing spraying antistatic electricity powder.
The beneficial effects of the utility model are:
In the cabinet front door-plate is housed; be easy to open maintenance; on the last door-plate instrument is installed, Microcomputer Protection, control button; can realize remote monitoring; automation control, isolating switch and circuit breaker are interlocked by flexible pipe, when isolating switch is in the separating brake position; isolated operation mechanism can not close a floodgate circuit breaker by flexible pipe effect breaker open operation button.Be in closing position otherwise work as circuit breaker, the circuit breaker main shaft is connected to interrupter, is that interrupter can not be operated, and finally reaches the interlocking effect.The employing flexible pipe connects, and prevents from transporting the interlocking that is out of shape off normal in the installation process and causes and loses efficacy.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is internal structure schematic diagram of the present utility model;
Fig. 3 is side-looking structural representation of the present utility model;
Fig. 4 is electrical connection diagram of the present utility model.
Among the figure: door-plate, 14-electroscopy equipment, 15-interlocking flexible pipe, 16-instrument, 17-Microcomputer Protection, 18-control button under 111-cabinet, 1-secondary control room, 2-breaker chamber, 3-cable vault, 4-isolating switch, 5-circuit breaker, 6-isolating switch form, 7-cable vault form, 8-electromagnetic lock, 9-current transformer, 10-copper conductor, 11-bus-bar room, the last door-plate of 12-, the 13-.
Embodiment
See also Fig. 1 to shown in Figure 4, a kind of small-sized ring main unit, comprise cabinet 111, and be installed in last door-plate 12 and the following door-plate 13 of cabinet 111 front ends, described cabinet 111 is divided into secondary control room 1, bus-bar room 11, breaker chamber 2 and cable vault 3 from top to bottom, described cabinet 111 inside are equipped with isolating switch 4, circuit breaker 5, current transformer 9, the electroscopic device 14 that connects by copper conductor 10 successively, and 5 of described isolating switch 4 and circuit breakers are provided with flexible pipe interlocking 15.
Preferably; described isolating switch form 6, instrument 16, Microcomputer Protection 17, the control button 18 that isolating switch 4 positions are installed on the door-plate 12 of going up; on the described down door-plate 13 isolating switch panel (not shown) and circuit breaker panel (not shown) are installed, and are installed in described time door-plate 13 and can prevent the charged electromagnetic lock 8 of opening cabinet.
Preferably, also be provided with cable vault's form 7 on the described following door-plate 13, described secondary control room 1, bus-bar room 11, breaker chamber 2 and cable vault 3 adopt the SMC insulating material to separate successively, and described upper and lower door-plate (12,13) all adopts cold drawing spraying antistatic electricity powder.
The beneficial effects of the utility model are:
In the cabinet front door-plate is housed; be easy to open maintenance; on the last door-plate instrument is installed, Microcomputer Protection, control button; can realize remote monitoring; automation control, isolating switch and circuit breaker are interlocked by flexible pipe, when isolating switch is in the separating brake position; isolated operation mechanism can not close a floodgate circuit breaker by flexible pipe effect breaker open operation button.Be in closing position otherwise work as circuit breaker, the circuit breaker main shaft is connected to interrupter, is that interrupter can not be operated, and finally reaches the interlocking effect.The employing flexible pipe connects, and prevents from transporting the interlocking that is out of shape off normal in the installation process and causes and loses efficacy.
