Description
Technical field
The utility model relates to a kind of metering cabinet, is specially a kind of intelligent grid protection high pressure expense control metering cabinet.
Background technology
The metering cabinet that current power department uses mostly is the function singleness product, only possesses function of measuring and lacks defencive function, and old equipment is in operation and often can causes the metering cabinet damage accident because overvoltage, overcurrent appear in circuit.And this accident very easily feeds through to the tripping operation of upper level transformer station, causes the large tracts of land user to have a power failure, and leads to larger accident.This situation happens occasionally current power is in service.
On the other hand, traditional outdoor measurement cabinet is because of without switching device, and not possessing rations the power supply operates a switch, the load control function, and interruption maintenance is very inconvenient.
Also have, traditional outdoor measurement cabinet lacks expense control function, does not possess the function of electrical network intelligent management, to the management of the taking over of the electricity charge, power consumption equipment, makes troubles.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of intelligent grid protection high pressure expense control metering cabinet, to solve the problem that proposes in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
a kind of intelligent grid protection high pressure takes the control metering cabinet, the cabinet door that comprises the metering cabinet cabinet and be connected with cabinet, between cabinet door and cabinet, by the gate inhibition with anti-stealing electricity function, be connected, the cabinet door is provided with indicator light, cabinet is provided with louvre, on electric power incoming line in cabinet, be connected with circuit breaker in turn, combination transformer and batch meter, described batch meter is connected with the metering anti-electricity-theft device by load control unit, computer integrated protection respectively with circuit breaker, current transformer protection winding in metering anti-electricity-theft device and combination transformer connects, voltage transformer power supply winding in combination transformer respectively with circuit breaker, computer integrated protection, load control unit is connected with the metering anti-electricity-theft device, described metering anti-electricity-theft device is connected with remote control center by microprocessor.
Further, described combination transformer is that poured with epoxy resin is integral the formula structure.
Beneficial effect:
The utility model volume is little, protects safe and reliablely, and accurate measurement, can be anti-electricity-theft, and intelligent folding; Realized that expense is controlled, the remote measurement of remote control.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is circuit structure diagram of the present utility model.
Embodiment
In order to make of the present utility modelly to realize technological means, creation characteristic, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
as Fig. 1, shown in Figure 2, a kind of intelligent grid protection high pressure takes the control metering cabinet, comprise metering cabinet cabinet 12 and the cabinet door 13 that is connected with cabinet 12, between cabinet door 13 and cabinet 12, by the gate inhibition 14 with anti-stealing electricity function, be connected, cabinet door 13 is provided with indicator light 16, cabinet 12 is provided with louvre 15, on electric power incoming line 1 in cabinet 12, be connected with circuit breaker 2 in turn, combination transformer 3 and batch meter 4, described combination transformer 3 is integral the formula structure for poured with epoxy resin, described batch meter 4 is connected with metering anti-electricity-theft device 6 by load control unit 5, computer integrated protection 7 respectively with circuit breaker 2, current transformer protection winding 8 in metering anti-electricity-theft device 6 and combination transformer 3 connects, the voltage transformer power supply winding 9 of combination transformer 3 respectively with circuit breaker 2, computer integrated protection 7, load control unit 5 is connected with metering anti-electricity-theft device 6, described metering anti-electricity-theft device 6 is connected with remote control center 11 by microprocessor 10.
In the utility model, when overvoltage, overcurrent accident appearred in user side, computer integrated protection 7 output trip signals carried out separately circuit breaker 2 to circuit breaker 2, and measurement loop has cut off the connection with the upper level circuit, avoids feeding through to upper level transformer station.Effectively protected the safe operation of whole circuit.Effectively avoided being in operation and caused the metering device damage accident because overvoltage, overcurrent appear in circuit.
As long as described circuit breaker 2 has obvious disjunction folding function, during maintenance, circuit breaker 2 disjunctions, just can break away from whole circuit, and have good fracture.After disconnection, make the repair and maintenance safety and reliability, overcome the defect of former interruption maintenance inconvenience.At needs, ration the power supply and operate a switch, also realize very easily during load control.
Described metering anti-electricity-theft device 6 has the function of Omnibearing anti-electricity-theft, with remote control center 11, coordinates, and has realized remote control, telemetry function.Load control unit 5 monitors the ruuning situation of load at any time, when occurring exceeding the numerical value situation of design standard, and the signal of operating a switch so that output is rationed the power supply.Metering anti-electricity-theft device 6 coordinates with load control unit 5 with computer integrated protection 7, makes intelligentized management functions such as the utlity model has protection, expense control metering, switch, Omnibearing anti-electricity-theft, remote-control romote-sensing.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
