Abstract
The utility model discloses a remote oil level monitoring and alarm device for a distribution transformer. The device comprises a liquid level switch and a global system for mobile communications (GSM) control module, wherein the liquid level switch is arranged in a glass oil leveler pipe or an oil storage tank of the distribution transformer, the normally-open output contact of the liquid level switch is connected with a signal input end of the GSM control module, and a signal output end of the GSM control module is in communication with a mobile phone of a maintenance person. When the oil level is lowered to an extreme position due to oil leakage of the distribution transformer, the output contact of the liquid level switch is closed, the GSM control module is started to send alarm information to the maintenance person, and the maintenance person is reminded to arrive at the site timely to eliminate faults, so that automatic monitoring of the oil level in operation of the distribution transformer is realized, and safe operation of equipment is ensured.
Description
Technical field
The utility model relates to the warning device of substation transformer, relates in particular to a kind of substation transformer oil level remote monitoring warning device.
Background technology
At present, in electric system, power supply reliability is the important indicator of the examination quality of power supply, has reflected the satisfaction degree of power industry to the national economy power requirement, and State Grid Corporation of China reaches more than 99.9% the urban electricity supply reliability that society promises to undertake now.The factor that influences power supply reliability is many, and except that irresistible inclement weather, what the accounting example was maximum is exactly device damage.The present substation transformer of China is oil-filled transformer mostly; Leakage of oil, oil level is on the low side is again the one of the main reasons that causes such transformer to damage; Because the distribution of substation transformer is closeer; Can not carry out the round-the-clock artificial operation conditions of keeping watch on, crossing when hanging down when oil level to influence the work of transformer, thereby causes power supply quality unreliable.
The utility model content
The purpose of the utility model provides a kind of substation transformer oil level remote monitoring warning device, can realize the operating oil level of substation transformer is monitored automatically, guarantees equipment safety operation.
The utility model adopts following technical proposals: a kind of substation transformer oil level remote monitoring warning device; Comprise level switch, GSM control module; Described level switch is arranged in the glass oil ga(u)ge pipe of substation transformer or in the storage tank; The output contact of often opening of level switch is connected with the signal input part of GSM control module, and the signal output part of GSM control module and maintainer's mobile phone communicate.
Described level switch is the float-ball type level switch.
The utility model substation transformer oil level remote monitoring warning device; When the substation transformer leakage of oil causes oil level to be reduced to extreme position; The output contact of level switch is closed, starts the GSM control module and sends out warning information to the maintainer, reminds maintainer's elimination fault of in time reaching the spot; Realization is monitored the operating oil level of substation transformer automatically, guarantees equipment safety operation.
Description of drawings
Fig. 1 is the theory diagram of the utility model.
Embodiment
As shown in Figure 1; A kind of substation transformer oil level remote monitoring warning device; Comprise level switch, GSM control module, described level switch is arranged in the glass oil ga(u)ge pipe of substation transformer or in the storage tank, the output contact of often opening of level switch is connected with the signal input part of GSM control module; The GSM control module is positioned in the ammeter box, and the signal output part of GSM control module and operator's mobile phone communicate.The GSM control module is a kind of high-end wireless data sending opertaing device; Adopt the GSM transceiver module and high-performance 32 bit processors of SIEMENS technical grade, realize that through GSM net SMS service function (place of the GSM network coverage) data wireless, long distance transmit control.Described level switch is the float-ball type level switch.The utility model is applicable to the substation transformer of capacity below 800KVA; Warp is at subsequent use substation transformer analog machine spillage test; When the ball float of oil level decline drive level switch fell to dry-reed contact, under the effect of ball float internal magnet, dried spring was often opened the closed GSM of startup of output contact control module; The GSM control module is sent the warning information of " XXX place substation transformer oil level reduces; please handle " immediately to the mobile phone that is provided with in advance, the maintainer in time handles after receiving information, effectively avoids interrupting because of device damage the influence of user's power supply.
