Abstract

The utility model discloses a security alarm system for a transformer, which is characterized in that a cylindrical appearance detection device is arranged on the transformer and a monitoring terminal is arranged close to the transformer. A temperature sensor for measuring oil temperature of the transformer, a liquid level sensor for measuring oil quantity of the transformer, a shake sensor for measuring shake, an inclination sensor for measuring inclination, a short-distance wireless module, a chip for managing signal transmission and a disposal battery are arranged in the cylindrical appearance detection device. The monitoring terminal is provided with a short-distance wireless module and a chip for managing signal transmission and achieves communication with the cylindrical appearance detection device. The monitoring terminal is further provided with a general packet radio service (GPRS) or code division multiple access (CDMA) communication module and connected respectively with mobile phones of security personnel in charge and a backstage data center through a GPRS or CDMA network. The security alarm system for the transformer has the advantages of being simple in structure, capable of saving labor and material resources in check-up, management and maintenance of the power transformer, convenient in use and good in effect.

Description

A kind of transformer safety alarm system

Technical field:

The utility model relates to a kind of technical field of security and protection; Be particularly related to a kind of transformer safety alarm system; Produce when unusual at transformer state; Through Radio Transmission Technology and internet transmission technology, data are sent on computer backstage and the security protection person liable mobile phone, realize the purpose that the power transformer state is monitored in real time.

Background technology:

Development along with national grid; The geographic distribution of power equipment becomes and disperses very much; When the power equipment in isolated area or the remote mountains is damaged and during problem such as theft, is difficult in time find, the management and the security protection system of power equipment are had higher requirement.Such as information such as the oil level of transformer and temperature is to rely on the staff to check to the scene just can obtain, and lot of manpower and material resources is wasted in regular like this inspection.Under such background, need the ERST infosystem of cover reverse power transformer operation in time, make power department to the power transformer inspection, administer and maintain more science.

The utility model content:

The purpose of the utility model provides a kind of transformer safety alarm system, to overcome present power department to the inspection of power transformer, when administering and maintaining, wasting manpower and material resources's shortcoming.

In order to realize above-mentioned purpose, a kind of transformer safety alarm system that the utility model provides, concrete technical scheme is: transformer is provided with near the monitoring terminal cylindrical shape pick-up unit and the transformer; Be provided with the temperature sensor of measuring transformer oil temperature, the level sensor of measuring transformer oil mass, the shake sensor of measurement shake and chip, the disposable battery of inclination sensor, short-distance wireless module and supervisory signal transmission that measurement is tilted in the described cylindrical shape pick-up unit; Described monitoring terminal is provided with the chip of short-distance wireless module and supervisory signal transmission, realizes communicating by letter with the cylindrical shape pick-up unit; This monitoring terminal also is provided with GPRS or CDMA communication module, and the network through GPRS or CDMA is connected with security protection person liable mobile phone and background data center respectively; The upper end of this cylindrical shape pick-up unit is a seal box 1, is provided with shake sensor, inclination sensor, short-distance wireless module, managing chip and disposable battery at seal box 1; The lower end of this cylindrical shape pick-up unit and lower end are respectively arranged with the fuel level sensor 2 that is sealed in the etui and make longilineal temperature sensor 3; Sealing box 1, fuel level sensor 2 and make longilineal temperature sensor 3, the three is joined together to form cylindric.

It is simple to adopt the utlity model has of above-mentioned measure to install, to the inspection of power transformer, administer and maintain and can use manpower and material resources sparingly, advantage easy to use, effective.

Description of drawings:

Fig. 1 is the utility model FB(flow block);

Fig. 2 is the cylindrical shape pick-up unit synoptic diagram of the utility model.

Below in conjunction with accompanying drawing to the utility model further detailed explanation again.

Embodiment

With reference to figure 1; Fig. 1 is the utility model FB(flow block); Can find out that from Fig. 1 block diagram the characteristic of the utility model forms embodiment by pick-up unit, monitoring terminal and GPRS a kind of transformer safety alarm system or CDMA communication module, security protection person liable mobile phone and background data center: transformer is provided with near the monitoring terminal cylindrical shape pick-up unit and the transformer; Be provided with the temperature sensor of measuring transformer oil temperature, the level sensor of measuring transformer oil mass, the shake sensor of measurement shake and chip, the disposable battery of inclination sensor, short-distance wireless module and supervisory signal transmission that measurement is tilted in this cylindrical shape pick-up unit; This monitoring terminal is provided with the chip of short-distance wireless module and supervisory signal transmission, realizes communicating by letter with the cylindrical shape pick-up unit; This monitoring terminal also is provided with GPRS or CDMA communication module, and is connected with security protection person liable mobile phone and background data center respectively through the network of GPRS or CDMA; Near this transformer monitoring terminal gets final product near being installed in transformer.

With reference to figure 2; Fig. 2 is the cylindrical shape pick-up unit synoptic diagram of the utility model; The upper end of this cylindrical shape pick-up unit is a seal box 1, is provided with shake sensor, inclination sensor, short-distance wireless module, managing chip and disposable battery at seal box 1; The lower end of this cylindrical shape pick-up unit and lower end are respectively arranged with the fuel level sensor 2 that is sealed in the etui and make longilineal temperature sensor 3; Sealing box 1, fuel level sensor 2 and make longilineal temperature sensor 3, the three is joined together to form cylindric.During installation, with columned temperature sensor 3 one ends, the fuel temperature measurement mouth that is inserted on the transformer panel gets final product, and installs very convenient.

The utility model be achieved in that when transformer stolen or occur, shake, the oil temperature is too high or transformer oil liquid level when crossing situation such as low; Sensor sends alerting signal; Wake the short-distance wireless communication module in the right cylinder pick-up unit up; Near the short-distance wireless communication module sends to alerting signal monitoring terminal; This monitoring terminal is sent to alerting signal on computer background data center of our department and the security protection person liable mobile phone, so that in time handle unusual accident through GPRS or cdma network.
