Description
Technical field
The utility model relates to power supply or distribution control technology field, is specifically related to a kind of remote monitoring formula switchgear house decompression recovery device.
Background technology
In the switchgear house of residential quarter, oil field; extensively adopt frame-type circuit breaker as the low pressure master switch; when running into the power grid accident instantaneous power-off; as the tripping operation of high-tension line transient fault, planned power failure etc.; because of the o-volt protection effect of the switchgear house circuit breaker tripping operation of threading off; after the power system restoration power supply, it all is to rely on the artificial execute-in-place that arrives that the switchgear house combined floodgate send electricity to work, and workload is big, the recovery electric power feeding time is long.Especially when bad weather, power grid accident is frequent, the tripping operation of switchgear house no-voltage trip occurs repeatedly, producing under the limited situation of vehicle, it is longer to recover electric power feeding time, and remote switchgear house can't guarantee in time to recover user's power supply especially, causes user's interests to incur loss, complaint increases, and has influenced power supply enterprise's service quality.Power department solves the emergency method of this type of problem, normally takes to remove the way of no-voltage trip defencive function, and this method will cause moment impact, and the harm that is brought all is totally unfavorable concerning electrical network or user, is helpless a kind of method.
In the prior art, similarly switchgear house decompression recovery device does not possess remote functionality, and the operator on duty can't in time understand switchgear house and send electric situation, and outside decompression is differentiated, time-delay recovers to send the electric work energy automatically and the supervising device with remote control function does not possess.Described in the Chinese patent ZL 03240867.6 a kind of automatic switch no-voltage trip reclosing device, by detecting circuit breaker position signal, no-voltage trip signal, inner over-current signal, manual brake separating signal and power quality situation, at the laggard line delay reclosing of no-voltage trip power system restoration, reach and send electric purpose automatically, but this device does not possess remote monitoring function, the operator on duty can't long-range understanding breaker closing situation and is installed self action situation, and circuit structure is too complicated.Described in the Chinese patent ZL 200820021242.9 a kind of switchgear house intelligent remote measuring remote control, the implementation of circuit has adopted traditional single-chip microprocessor MCU, by writing the control of corresponding control programs completion logic, and use finished product industry GPRS communication module as the controlled terminal communicator, computer background is finished remote control functions such as warning, remote control combined floodgate as main control end.The sampling input of this device is by detecting the method for circuit breaker trip position signalling, after circuit breaker or the contactor tripping operation, send remote alarm by the GPRS communication module, finishing the switchgear house transmission process with manual remote control more equally.This device does not possess the decompression time-delay and recovers automatically to send the electric work energy, but a kind of remote control.
In addition, in the above technical circuit design, logic control part and remote functionality module all adopt single-chip microcomputer and industrial GPRS communication module.The Single-chip Controlling program is once curing, be not easy to the staff and revise to adjust and be provided with, and the single-chip microcomputer interference that very easily is subjected to forceful electric power magnetic occurs unusually, and reliability is affected.In the existing remote control technology, telecommunication adopts the mode of short message receiving-transmitting+computer background, transmission speed is slow, be unfavorable for distribution operator on duty mobile monitor, and its each parts (power supply, input detection, logic control, GPRS module) are independent devices, cause the device combined volume excessive.Simultaneously, the cost of industrial GPRS communication module and running cost are all higher, have limited applying in middle-size and small-size power distribution equipment.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, a kind of low cost, integrated is provided, and the switchgear house circuit breaker decompression that possesses wireless remote monitering detects, the remote monitoring formula switchgear house decompression recovery device of selectivity time-delay automatic closing technical scheme.
Its technical scheme is: comprise binding post, logic processing circuit plate, power module, communication module, counter and display screen.Described binding post is divided into voltage detection terminal, current detecting terminal and combined floodgate control terminal, described logic processing circuit is connected with voltage detection terminal, current detecting terminal and combined floodgate control terminal respectively, voltage detection terminal also is connected with the input of power module, an output of power module is connected with logic processing circuit, its another output is connected with communication module, and communication module also is connected with display screen; Described logic processing circuit also is connected with counter.
Wherein, described logic processing circuit is single chip circuit or is combined into by at least 4 delay circuits.Described communication module is GSM, GPRS or CDMA module.
The utility model compared with prior art, has following advantage: 1, differentiate automatically and distinguish the outside decompression of switchgear house, internal short-circuit over current fault, detect switchgear house mains side recovery situation, the time-delay automatic closing send, minimizing personnel, vehicle driving number of times, shorten the accident interruption time, improve electricity consumption service quality, safeguard corporate reputation.2, realize remote functionality by long distance wireless virtual speech agreement, the keeper can not be subjected to distance limit, understand switchgear house decompression recovery situation, failure condition by remote signalling, remote measurement, necessity is to close a floodgate by remote control, has realized switchgear house decompression recovery remote monitoring.3, adopt low-cost circuit engineering scheme and virtual speech GSM signaling, be convenient to popularize the application of the remote wireless network communication technology in middle-size and small-size power distribution equipment, increase work efficiency and automaticity, for enterprise brings higher benefit.
