Description
Technical field
The present invention relates to a kind of intelligent alarm transformer and include the distribution transformer system of this transformer.
Background technology
At field transformer, because the value of transformer is expensive, and be related to the bulk supply of certain area, so its fail safe is most important, but the event of stealing transformer in reality occurs repeatedly, cause huge loss to the production of the country and people and life.As in 2003,110 kilovolts, In Qiannan Fuquan City good fortune linen thread two parallel circuits fall bar, cause this line outage 10 hours 26 points, cause economic loss more than 108 ten thousand yuan; The first two season in 2005, the theft of Sichuan Province Power Co., Ltd system, destruction electric power facility incidence of criminal offenses more than 550, direct economic loss is more than 2,600,000 yuan.In recent years, be singly that the direct economic loss one that electric power facility is stolen caused is just more than 200,000,000 yuans.Along with the development of modern electric power industry, China's town and country electric power covers substantially, and distribution transformer has been distributed in each corner domestic; The pilferage transformer crime means of offender is also in raising, and the stolen event of distribution transformer gets more and more, and along with the rapid growth of user power utilization demand and power quality, transformer anti-theft will become a social concern merited attention.
The antitheft work of the distribution such as existing transformer mainly have employed the technology such as anti-theft lock, anti-theft nut, there is wireless and Wired anti-theft alarm subsequently, as GSM (Global System for Mobile Communications popular at present, i.e. global system for mobile communications, be commonly called as " Global Link ") Radio Transmission Technology is a kind of mobile communication technology standard originating from Europe.China introduces in early 1990s and adopts technique standard, and at present, China Mobile, CHINAUNICOM respectively have a GSM net, are mobile communications network the biggest in the world.Gsm system comprises several frequency range such as GSM900:900MHz, GSM1800:1800MHz and GSM-1900:1900MHz.
For current transformer, said GSM Radio Transmission Technology has compared and has been widely used in potential transformer burglar alarm, the transformer power-off alarm namely with gsm wireless transfer function supports three-phase electricity power alarm, there is inspection function, automatically send at set intervals and patrol and examine report information, can with alarm center network alarm.
Existing burglar alarm comprises alarm, receiver module, GSM transmitter, GPRS transmitter, monitor network and monitoring telephone, wherein, alarm is connected with receiver module, the output of receiver module is connected with GPRS transmitter with GSM transmitter respectively, GSM transmitter is connected with monitoring telephone, and GPRS transmitter is connected with monitor network.
On the electric pole that existing voltage transformer wireless monitoring alarm is generally arranged on monitored power line or near transformer, when power line or transformer once there is stolen or three-phase broken string or power-off condition, warning device can be found out immediately and be reported to the police to GSM/CDMA Receiving Host with wireless GSM/CDMA short message and/or voice mode.This mode is the transformer of domestic employing radio alarming technology the most common at present, this transformer utilizes GSM message breath data-transmission mode and phonetic function platform to complete remote transmission and the control of intelligent alarm data, the type warning device has practical function, superior in quality, the features such as working stability is reliable, be adapted to outdoor various environment, therefore be widely used in electric power, oil, in all power equipments worked out of doors such as mine, because GSM global radio mobile communication network quorum sensing inhibitor area is wide, the overlength distance achieving low-price high-quality is convenient, intelligent radio controls and reports to the police flexibly, solve the limitation of the wired or wireless high-power controlling alarm of landline telephone.
But, the transformer of existing employing radio monitor alarm device also exists following defect: (1) is due to by the electric pole of potential transformer burglar alarm is arranged on monitored power line or transformer, because alarm target is obvious, the extraneous factors such as easy person thefted are destroyed, if thief first destroys alarm, block the teletransmission warning function of alarm, effectively can not be reported to the police by GSM mode after transformer power-off, so the fail safe of this alarm is not good enough; (2) alarm is mainly by external solar power taking, because device is by external electricity, is easily subject to weather conditions, external disturbance, drain conditions impact, may occur because be subject to the impact of above-mentioned factor but not stolen and occur false alarm.
In a word; the anti-theft measures such as above-mentioned anti-theft lock, anti-theft nut; and the wireless and Wired anti-theft alarm occurred subsequently; owing to not forming integrative-structure with transformer; and theft personnel constantly study the theft mode made new advances at present; the alarm of anti-theft lock, anti-theft nut and split can not play due protective effect to distribution transformer after installing, and receive serious threat in the safety of distribution transformer from far-off regions especially, this problems demand solves.
Summary of the invention
Technical problem to be solved by this invention is for above shortcomings in prior art, provides that a kind of security performance is good, anti-theft feature is not easy the intelligent alarm transformer be found and the distribution transformer system comprising this transformer.
The technical scheme that solution the technology of the present invention problem adopts is that this intelligent alarm transformer comprises transformer body and burglar alarm, described transformer body comprises oil tank of transformer, described burglar alarm comprises the alarm unit for sending warning message and the unit of receiving a crime report for receiving described warning message, wherein, described alarm unit is located at the inside of described oil tank of transformer.
Preferably, described alarm unit comprise according to judge transformer body whether power-off determine whether the alarm of reporting to the police, described alarm comprises the transmitting antenna for sending warning message, the outer wall of described oil tank of transformer is provided with perforation, and described transmitting antenna extends to the outside of oil tank of transformer through described perforation.
Further preferably, also include the through device of insulation in described alarm unit, the through device of described insulation is arranged in described perforation, and described transmitting antenna passes from the through device of described insulation.
