Abstract

The invention discloses a multifunctional warning device of a transformer. The device comprises a GIS management system, a power-down detection module, an infrared detection module, a controller, a delayer, a GPRS module and an alarm. The power-down detection module, the infrared detection module, the controller and the delayer are connected with the controller, the alarm and the GPRS module are connected with the delayer, and the GPRS module communicates with the GIS management system. If the controller always receives the signal, indicating that personnel move, sent by the infrared detection module for a long time and also receives a transformer outage signal sent by the power-down detection module in the time period, the controller controls the alarm to send an alarm. Meanwhile, the signals are transmitted to the GIS management system through the GPRS module, schedule staff immediately send people near the transformer to check the transformer after obtaining information, so that safety of the transformer is improved and the probability that coils of the transformer are stolen is reduced.

Description

Transformer multifunctional warning device

Technical field

The present invention relates to the oil-immersed power transformer in transformer technology field, be specifically related to for checking whether transformer occurs the transformer multifunctional warning device of safety problem.

Background technology

Transformer (Transformer) is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc., it is widely used in electric system, spread all over various places, town and country, the coil of transformer is by the coiling of precious metal copper, due to it, to be arranged on field unattended, and some lawless persons just can steal the coil in transformer, and cause damage to people's property affects daily life simultaneously, particularly outlying mountain area, the life that makes people inconvenience very.

Because transformer is often arranged on field, the difference variation in field is larger, causes the fluid liquid level in oil tank of transformer to change greatly, will cause the iron core of transformer, winding to burn because of overheated if supplement not in time transformer oil after pasta reduces.

Summary of the invention

For above-mentioned deficiency of the prior art, object of the present invention will provide a kind of transformer multifunctional warning device exactly, the problem that its coil that can effectively solve the transformer that is arranged on field is stolen.

The object of the present invention is achieved like this: transformer multifunctional warning device, comprise GIS management system,

Cause the detection of power loss module of consumer cisco unity malfunction for detection of transformer power-off, dead electricity or can't meet the quality requirement of electricity;

The infrared detection module that whether has personnel to move for detection of the position that transformer is installed;

The controller transforming for the signal that detection of power loss module and/or infrared detection module are passed back;

Carry out the chronotron of delay process for the information after controller is transformed;

For the power-off signal after chronotron delay process and personnel's movable signal being passed to the GPRS module of GIS management system;

And, the alarm that the alerting signal that controller is sent responds;

Described detection of power loss module, infrared detection module and chronotron are all connected with controller, and described alarm is all connected with chronotron with GPRS module, and described GPRS module and GIS management system communicate.

That transformer multifunctional warning device also comprises and is connected the liquid level sensor for monitoring oil tank of transformer liquid level with controller as further scheme of the present invention.

Also to comprise that one for the standby power supply to described transformer multifunctional warning device power supply as the further scheme of another kind of the present invention.

Beneficial effect of the present invention is: infrared detection module will detect after external staff's signal, this signal is passed to controller, if controller receives the signal that infrared detection module passes over for a long time always, and within this time period, also receive the signal of transformer power-off, just controlling alarm reports to the police, this signal is passed to GIS management system through GPRS module simultaneously, near can sending immediately transformer after regulation and control personnel obtaining information, personnel check transformer, thereby have improved the transformer security that is arranged on field.

Liquid level sensor passes to the oil mass liquid level information in oil tank of transformer to controller, after liquid level information that liquid level sensor is passed back is lower than settings, controller will be controlled alarm and report to the police, this signal is passed to GIS management system through GPRS module simultaneously, near can sending immediately transformer after regulation and control personnel obtaining information, personnel check transformer, too low to prevent oil tank liquid level, cause the iron core of transformer, winding to burn because of overheated.

Accompanying drawing explanation

Fig. 1 is transformer multifunctional warning device theory diagram.

Embodiment

As shown in Figure 1, this transformer multifunctional warning device comprises GIS management system, causes the detection of power loss module of consumer cisco unity malfunction for detection of transformer power-off, dead electricity or can't meet the quality requirement of electricity; The infrared detection module that whether has personnel to move for detection of the position that transformer is installed; The controller transforming for the signal that detection of power loss module and/or infrared detection module are passed back; Carry out the chronotron of delay process for the information after controller is transformed; For the power-off signal after chronotron delay process and personnel's movable signal being passed to the GPRS module of GIS management system; The alarm that the alerting signal that controller is sent responds; And, for monitoring the liquid level sensor of oil tank of transformer liquid level.

Described detection of power loss module, infrared detection module, liquid level sensor and chronotron are all connected with controller, and described alarm is all connected with chronotron with GPRS module, and described GPRS module and GIS management system communicate.

Also to comprise that one for the standby power supply to described transformer multifunctional warning device power supply as another kind of scheme of the present invention.

Below the course of work of transformer multifunctional warning device is described:

The signal that infrared detection module, liquid level sensor and detection of power loss module moment are detected passes to controller:

If controller receives for a long time infrared detection module and passes over the signal that personnel move always, and within this time period, also receive the transformer power-off signal that detection of power loss module transmits, controller will be controlled alarm and report to the police, this signal is passed to GIS management system through GPRS module simultaneously, near can sending immediately transformer after regulation and control personnel obtaining information, personnel check transformer, improve the security of transformer, reduce the possibility that transformer coil is stolen.

If the signal that detection of power loss module passes over is, any signal in can't meet the quality requirement of transformer power-off, dead electricity or electricity, regulation and control personnel just occur that to transformer the reason of this situation searches with electrical network by locality, so that transformer recovers normal work as early as possible.

Although by reference to the accompanying drawings the specific embodiment of the present invention is described in detail, should not be construed as the restriction of the protection domain to this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
