Abstract
The utility model relates to a cordwood system intelligent ring network cabinet as a unit ring network cabinet, comprising an element unit (1) and a cable unit (2), wherein the element unit (1) is connected with the cable unit (2) by a plurality of gas box sleeves (7) and a plurality of outlet sleeves (3) are mounted on the upper part of the element unit (1) and one side of the element unit (1) is provided with an operation mechanism (6) and a vacuum circuit breaker (5) is mounted on the upper end of each gas box sleeve (7) in the element unit (1) and an isolation switch (4) is mounted on each vacuum circuit breaker (5) and a plurality of inlet sleeves (9) are mounted at one side of the cable unit (2) and the gas box sleeve (7) in the cable unit (2) is connected with corresponding fuse protectors (8). The cordwood system realizes the low-carbon industry of the switch element and corresponds with the environmental protection condition; the cordwood system design reduces the unit connection and the core unit of the ring network cabinet is not affected at the abnormal condition and the power supply reliability is provided; the production management and operation maintenance are simple and convenient.
Description
Technical field
The utility model relates to a kind of power distribution network with control and protection equipment, especially a kind of security of operation and ring main unit flexibly, the intelligent ring main unit of specifically a kind of cordwood system type.
Background technology
Ring main unit is that one group of high voltage switchgear is contained in the steel sheet metal cabinet or makes the electric equipment of assembly unit compartment ring network power supply unit, on-load switch and fuse are adopted in its core, have simple in structure, volume is little, price is low, can improve power supply parameter and advantages such as performance and power supply safety.It is widely used in the power distribution station and box-type substation of load centers such as Urban House sub-district, skyscraper, large public building, factory and enterprise.
Traditional and external ring main unit, adopt the combination full-closed structure, in the structure of a ring main unit, the public case chamber of a plurality of power supply units is arranged, each power supply unit operational mode occurs and changes, and can not change the position and the arrangement form of ring main unit unit between the unit according to user's needs.Its volume is big, maintenance inconvenience, and the accident that causes is more, in case local fault takes place, needs to check, change that this is impossible for being total to box structure that plant maintenance also is difficult to be solved preferably.To directly influence power supply reliability and operations staff's safety in this case.Therefore, the traditional and external totally-enclosed box structure altogether operation that ring main unit adopted is dangerous, dumb, can not satisfy the needs of prior art.
Summary of the invention
The purpose of this utility model is at tradition and the external dangerous and inflexible problem of the existing operation of ring main unit structure, proposes a kind of security of operation, the intelligent ring main unit of cordwood system type flexibly.
The technical solution of the utility model is:
A kind of cordwood system type intelligence ring main unit, it is a unit ring main unit, this unit ring main unit comprises cell and cable unit, be connected by a plurality of gas tank sleeve pipes between described cell and the cable unit, a plurality of outlet sleeve pipes are equipped with on the top of cell, one side of cell is equipped with operating mechanism, vacuum circuit-breaker all is equipped with in the upper end of each gas tank sleeve pipe in the cell, on each vacuum circuit-breaker isolating switch is installed, one side of cable unit is equipped with a plurality of entrance bushings, and each gas tank sleeve pipe is continuous with corresponding a plurality of fuses in the cable unit.
Isolating switch of the present utility model is a tri-station isolating switch.
Outlet sleeve pipe of the present utility model and entrance bushing are three.
Operating mechanism of the present utility model is spring operating mechanism or permanent-magnet operating mechanism.
Vacuum circuit-breaker of the present utility model is an on-load switch.
The beneficial effects of the utility model:
The utility model with controlling and protection equipment, has overcome the dangerous and inflexible problem of operation of the version existence of tradition and overseas equipment as power distribution network.It is applicable to industrial and mining enterprises, residential quarters, skyscraper and distribution systems such as school, park, as ring network power supply unit and the terminal controller switching equipment of indoor interchange three-phase 6-24KV, 50Hz.Can cut-off and the pass is closed nominal load current, closed and to close rated short circuit current, also can cut-off no-load transformer electric current, capacitance current.This ring main unit adapted spring mechanism (both can be electronic, again can manually) operational load switch, ground connection cutter and isolation knife adapted manual-operating mechanism, and have telemechanical and far control function.
Do not produce any influence and contact between each unit of the present utility model mutually, independence is strong, installs, and is easy to maintenance, identical as modular construction, can change the position and the arrangement form of outlet according to the operation needs arbitrarily.
The utility model ring main unit adopts modular construction, combined and instant, thus the Quality Process that more can guarantee product is controlled the raising reliability of operation.The core cell of ring main unit can provide the complete production enterprise assembling of switchgear, the condition of the flexible change operational mode of operation power department.
Modular construction of the present utility model is changed into cellular construction with the ring main unit global design; Ring main unit is isolated and earthed switch with the vacuum circuit-breaker band; Connection between the unit is by cabinet top, unit, and all insulation is convenient to wiring change and expansion.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As Figure 1-3, a kind of cordwood system type intelligence ring main unit, it is a unit ring main unit, this unit ring main unit comprises cell 1 and cable unit 2, be connected by a plurality of gas tank sleeve pipes 7 between described cell 1 and the cable unit 2, a plurality of outlet sleeve pipes 3 are equipped with on the top of cell 1, one side of cell 1 is equipped with operating mechanism 6, it is on-load switch that vacuum circuit-breaker 5 all is equipped with in the upper end of cell 1 interior each gas tank sleeve pipe 7, each vacuum circuit-breaker 5 is that isolating switch 4 is installed on the on-load switch, one side of cable unit 2 is equipped with a plurality of entrance bushings 9, and each gas tank sleeve pipe 7 is continuous with corresponding a plurality of fuses 8 in the cable unit 2.
Isolating switch 4 of the present utility model is a tri-station isolating switch, connects conductive bit, isolates position, ground connection position.
Outlet sleeve pipe 3 of the present utility model and entrance bushing 9 are three.
The utility model replaces the SF6 arc extinguishing that tradition falls behind with vacuum circuit-breaker, realizes the low-carbon (LC) industry of switch element, meets environmental protection condition; Realization unitization design reduces interconnecting of each unit, makes between the core cell of ring main unit unaffectedly under exceptional condition, improves power supply reliability; Production management and operation maintenance are simple and convenient.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
