Abstract
The utility model relates to outdoor power supply and distribution equipment, in particular to an outdoor high-voltage intelligent demarcation vacuum circuit breaker. The vacuum circuit breaker comprises a housing; an A-phase insulating box, a B-phase insulating box and a C-phase insulating box are mounted in the housing; each insulating box is provided with a vacuum arc extinguish chamber arranged therein; two ends of each vacuum arc extinguish chamber are respectively and correspondingly connected with A, B and C phase incoming bushings or the three phases of outgoing bushings, and are equipped with on-and-off pull rod mechanisms; and particularly, zero-sequence transformers are mounted at the inner ends of the A, B, and C phase incoming bushings or the outgoing bushings; and current transformers are mounted on the A and C phase incoming bushings or outgoing bushings. By adopting the utility model, the single-phase grounding faults and phase faults can be automatically avoided, and when electric shock faults or leakage faults occur to a circuit, protection actions can be taken, and the power source is switched off. The vacuum circuit breaker is mainly used for agricultural 10 kV distribution circuits.
Description
(1) technical field: the utility model relates to power supply outdoor electricity distribution equipment, especially a kind of outdoor high-voltage intelligence boundary vacuum circuit-breaker.
(2) background technology: in recent years, along with the enforcement of projects to upgrade rural power grids, rural area 10KV distribution line transform " phase three-wire three " supply power mode of isolated neutral as by original " two lines, one ground " supply power mode.The change of 10KV distribution line supply power mode has strengthened the insulation level of distribution line, has reduced the trip-out rate of distribution line, has improved power supply reliability, has reduced line loss, and is significant.But the rural area 10KV distribution line of taking new supply power mode is in actual motion, single phase ground fault often takes place, particularly descend at severe weather conditions such as rainy season, strong wind and snow, single phase ground fault frequently takes place especially, has had a strong impact on safety, the economical operation of converting equipment and power distribution network.In addition in recent years, along with state net company progressively strengthens the safety in production to power supply enterprise at county level, the management intensity of operation and good service, each power supply enterprise at county level has also strengthened the power distribution station line loss that small towns power supply station is had jurisdiction over, the appraisal management of equipment safety operation, but because technological means does not catch up with, make power supply station big to rural power worker management difficulty, economic technique analysis also relies on artificial estimation, as: the test of platform district three-phase imbalance, it is conscious that the leakage switch test of platform district also relies on the rural power worker, and platform district load condition and idle situation can only be leaned on coulometric analysis (only limit is adorned the platform district of idle ammeter) or the like; Therefore, install on the referred agenda of power distribution automation, but traditional electrical power distribution automatization system is the system that the distribution management with real-time power distribution automation and off-line becomes one, the every complete function of distribution substation and main website, requirement height, passage realizes that difficulty is big, expense is high, causes in the long duration rural power grids to implement.So should seek to build a kind of adaptation rural power grids distribution monitoring system, satisfy the switching system of the single production and operation needs of basic unit.
(3) summary of the invention: the purpose of this utility model will solve existing outdoor vacuum circuit breaker exactly, in actual motion, single phase ground fault often takes place, have a strong impact on the safety of converting equipment and power distribution network, the problem of economical operation, a kind of outdoor high-voltage intelligence boundary vacuum circuit-breaker is provided.
Concrete scheme of the present utility model is: improve at common outdoor vacuum circuit breaker, it mainly contains shell, A, B, C three phase isolated box are housed in the shell, be provided with vacuum interrupter in each insulation booth, corresponding respectively A, B, C three-phase entrance bushing and the three-phase outlet sleeve pipe of connecting in the two ends of each vacuum interrupter, be equipped with the divide-shut brake drag link mechanism, it is characterized in that: the inner at A, B, C three-phase entrance bushing or outlet sleeve pipe is equipped with zero-sequence transformer; On A, C two-phase entrance bushing or outlet sleeve pipe, current transformer is housed respectively.
The utility model advanced and reasonable design, compact conformation.Built-in zero-sequence transformer summation current transformer can realize excising automatically single phase ground fault and phase fault, effectively protects the safety and economic operation of converting equipment and power distribution network.And, can realize that the automatic management of electrical network and power distribution network is had fault detection capability by at terminal configuration automatic intelligent control device, protection controlled function and communication function are widely used in rural area 10KV distribution line.

Among the figure: 1-outlet sleeve pipe, 2-shell, 3-divide-shut brake drag link mechanism, 4-entrance bushing, 5-zero-sequence transformer, 6-insulation booth, 7-vacuum interrupter, 8-current transformer.
(5) embodiment:
Referring to Fig. 1, Fig. 2, the utlity model has the basic structure of common outdoor vacuum circuit breaker, mainly contain shell 2, A, B, C three phase isolated box 6 are housed in the shell 2, be provided with vacuum interrupter 7 in each insulation booth, corresponding respectively A, B, C three-phase entrance bushing 4 and the three-phase outlet sleeve pipe 1 of connecting in the two ends of each vacuum interrupter, be equipped with divide-shut brake drag link mechanism 3, and do following the improvement: zero-sequence transformer 5 is installed in the inner at A, B, C three-phase entrance bushing 4; In A, C two-phase outlet sleeve pipe 1 the inner current transformer 8 is housed respectively.Promptly constitute the utility model.
Zero-sequence transformer 5 in the utility model can also be installed in the inner of A, B, C three-phase outlet sleeve pipe 1, and current transformer 8 is installed in the inner of A, C two-phase entrance bushing 1, it also is feasible perhaps zero-sequence transformer 5 summation current transformers 8 being installed in same end (end of incoming cables or leading-out terminal all can).
