Background technology
Known bypass breaker automaticity is not high, can not move use.
Summary of the invention
The utility model relates to a kind of mobile bypass breaker, the mobile bypass breaker of described one comprises main switch and cabinet, be mounted with successively from top to bottom LED display in cabinet front, communication interface, status display panel, high-tension cable output interface, on-load switch, high-tension cable input interface, door handle, and instrument transformer; Be mounted with successively from top to bottom control panel, output cable interface, SF6 switch and input cable interface at the cabinet back side.
Accompanying drawing explanation
By describing in more detail exemplary embodiment of the present utility model with reference to accompanying drawing, above and other aspect of the present utility model and advantage will become more and be readily clear of, in the accompanying drawings:
Fig. 1 is the Facad structure schematic diagram of a kind of mobile bypass breaker of the present utility model;
Fig. 2 is the structure schematic diagram of a kind of mobile bypass breaker of the present utility model.
Embodiment
Hereinafter, now with reference to accompanying drawing, the utility model is described more fully, various embodiment shown in the drawings.But the utility model can be implemented in many different forms, and should not be interpreted as being confined to embodiment set forth herein.On the contrary, it will be thorough with completely providing these embodiment to make the disclosure, and scope of the present utility model is conveyed to those skilled in the art fully.
Hereinafter, exemplary embodiment of the present utility model is described with reference to the accompanying drawings in more detail.
With reference to accompanying drawing 1,2, the mobile bypass breaker of described one comprises main switch and cabinet, is mounted with successively from top to bottom LED display in cabinet front, communication interface, status display panel, high-tension cable output interface, on-load switch, high-tension cable input interface, door handle, and instrument transformer; Be mounted with successively from top to bottom control panel, output cable interface, SF6 switch and input cable interface at the cabinet back side.
: product structure feature:
Adopt metal enclosed case structure, main switch and cabinet are fixed installation, and the compartment of primary heat transport system all has pressure relief device and passage, reliable ground, and seal perfect.The in-built on-load switch in switch gear room, the shell of this on-load switch is that poured with epoxy resin forms, and inside fills sulphur hexafluoride (SF6) gas, what this electricity cashier's office in a shop adopted is negative what switch cubicle that installs electro-motor additional.This cabinet has the self-locking quick plug-in terminal fitting easy to connect with external equipment simultaneously; This cabinet has control function, realizes long-range on/off switch function; Multifunctional digital ammeter, realizes the monitoring of electric weight.Four rolling is equipped with in this electric cabinet bottom, can move freely.
Native system is by length and the connected mode of the on-the-spot uninterrupted operation of flexible power cable bypass easily system power supply, just can in larger supply district, realize maneuverability, quick and safe carry out urban distribution network distribution line, the operations such as power supply unit (as bar change, case change, ring main unit, cable branch box etc.) and user's distribution system service without power-off, breakdown repair or interim power supply.The person and device security while guaranteeing to greatest extent distribution line uninterrupted operation, meet city and accompany dispatching of power netwoks, special user's temporary electricity and important place and major event reliable power supply and protect electric need of work.
: field of employment:
By the mobile bypass breaker of one, realize the service without power-off to distribution transformer on user's bar or the change of looped network case, need interior case for some time to become or looped network case paired running, also can carry out temporary transmission to important place.
While coordinating High-voltage generator set work, provide line sampling to High-voltage generator set, flow to High-voltage generator set and compare, guarantee that High-voltage generator set is incorporated into the power networks, uninterrupted operation.
: operation principle:
While operation at the scene, as long as by the I/O cable of running circuit breaker under electriferous state respectively with connection, on realization and bar, distribution transformer or looped network case become parallel running, the high-voltage switch gear that on then can first trip arm, distribution transformer or looped network case become, case change or looped network case are become to out of service, overhaul.After end-of-job, adopt in the same way, the high-voltage switch gear of pole transformer or the change of looped network case first closes, make pole transformer or looped network case become parallel running, disconnect a kind of high-voltage switch gear of mobile bypass breaker, the high-tension cable that charged dismounting connects, recovers to become normal operation by case, thereby realizes the repairing of distribution and change the object not having a power failure.
In the time that High-voltage generator set is incorporated into the power networks, a kind of mobile bypass breaker samples civil power, the control system that is transported to High-voltage generator set is compared, and parameter guarantee is provided for High-voltage generator set is grid-connected, and this equipment is that the operation of supporting high-voltage generator set grid-connection operation seamless switching is special.
The foregoing is only embodiment of the present utility model, be not limited to the utility model.The utility model can have various suitable changes and variation.All any modifications of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model within spirit of the present utility model and principle.
