Description of drawings:

Fig. 1 is the structural representation of intelligent transformer type control device of the present utility model;

Fig. 2 is the circuit diagram of intelligent transformer type control device of the present utility model;

Embodiment:

Referring to Fig. 1, Fig. 2, intelligent transformer type control device of the present utility model and long distance control system are sidepiece or top low pressure place or the next doors at transformer 1, are provided with intelligent control box 2, the casing exterior arrangement has lock-controlled switch 3, can play the effect of inner components and parts of protection and antitheft electricity; Box house is made of electric elements such as A.C. contactor 4, current transformer 5, GSM-IIIB remote meter reading extension set 6, electronic electric energy meter 7, control relay 8, display (not shown), wherein, A.C. contactor 4 is connected on the low pressure leading-out terminal of transformer 1, to realize the automatic switching of supply line; Current transformer 5 is connected on the terminals of GSM-IIIB remote meter reading extension set 6 and electronic electric energy meter 7 by transformer 1 each phase output line, be used to gather current signal, and can gather, analyze and handle accordingly data such as the power of transformer, electric current, voltage, load, temperature by GSM-IIIB remote meter reading extension set 6; Display is connected with GSM-IIIB remote meter reading extension set 6, is used to show whether the operating state of transformer 1 is normal.

GSM-IIIB remote meter reading extension set 6 is made up of electronic sensor, check meter warning device and single-chip microcomputer.Wherein, electronic sensor comprises temperature sensor 6-1 and unpacking transducer 6-2, and temperature sensor 6-1 is seated in the transformer and is connected with GSM-IIIB remote meter reading extension set 6 terminals, can carry out check and analysis to the operating temperature data of transformer 1; The transducer 6-2 that unpacks connects lock-controlled switch 3, has only the private key of use just can open control cabinet; The warning device of checking meter is by control relay 8 contacts control output, and dock with electronic electric energy meter 7 by the RS-485 interface, can measure the transformer power consumption by electronic electric energy meter 7, and be sent to administrative staff and control microcomputer by the data and the transformer fault signal of warning device of checking meter with electric energy meter, to realize electric energy metrical, remote meter reading and the management of power use.Single-chip microcomputer is used for the technical data of the existing transformer of storage computation, and detected data are carried out analyzing and processing, notes abnormalities in time to report to the police or control power supply output break-make.In this case, check meter warning device and single-chip microcomputer are installed in (not shown) in the GSM-IIIB remote meter reading extension set, and the warning device of checking meter is that product are directly purchased in market, and its structure repeats no more.

The operation principle of intelligent transformer type control device: when transformer overload, electric current or oily temperature are higher than set point, GSM-IIIB remote meter reading extension set 6 sends signal, and supply line is cut off in A.C. contactor 4 actions, realize automatic load removal, reach the purpose of current limliting, limited capacity.When the load or temperature reach just often, then realize closing a floodgate automatically or by Communication Control, guarantee the circuit normal power supply, under the overload situation, behind A.C. contactor 4 continuous switchings 3 times, it is normal that load can not reach, GSM-IIIB remote meter reading extension set 6 sends signal, cuts off supply line, no longer carries out automatic closing, send chimes of doom simultaneously, and to be demonstrated by signal lamp on display be why to hinder, and utilizes the mobile phone short message function to signal to administrative staff, utilizes communication function to signal to the remote monitoring computer simultaneously, notify administrative staff to handle by the monitor staff, make transformer 1 recover normal operation to the scene.When transformer 1 during in normal operation, the electricity consumption situation can be sent to supervisory control comuter by communication function at regular intervals, the electricity consumption peak valley is analyzed, and the day part power consumption added up, realize of the metering of long-range many rates to power consumption, alleviate administrative staff's labour intensity, reduce electric cost.

When the transformer operation is broken down; relevant components and parts action in the intelligent transformer device; transformer is protected automatically; and gather signals such as transformer associated voltage, electric current, power, temperature; be sent on power management staff's mobile phone and the control microcomputer; and utilize monitoring software to read in related data, show failure cause and send chimes of doom at once.The monitor staff can make corresponding statistics, analysis according to reason, number of times and the order of severity that transformer breaks down in a period of time, and takes appropriate measures, and avoids the generation once more of fault, guarantees the normal operation of transformer.Normative reference is (as overload when being built-in with the generation of transformer operation dependent failure on the single-chip microcomputer in the GSM-IIIB remote meter reading extension set in the intelligent transformer control device, overvoltage, phase shortage is under-voltage, outage, temperature is too high, stealing takes place, owe the parameter of the electricity charge) in the transformer running, when its above-mentioned parameter that detects transformer reaches the standard of setting, send dependent failure information, three-phase voltage when transformer being broken down with SMS transmission form, electric current, load, ambient temperature, situations such as working temperature feed back to the information transceiver (or in mandate mobile phone of administrative staff) of control microcomputer, and signal is read in the control microcomputer by it, be presented at above the display screen with the database form, and send chimes of doom by audio amplifier, remind administrative staff to note, make administrative staff can in time understand the failure condition of transformer, thereby it is in time handled.
