Abstract
The utility model relates to a monitoring of transformer oil position and intelligent regulation device, include and be used for monitoring the engine oil level sensor that the oil level changes, engine oil level sensor links to each other with the AD conversion unit circuit, be connected with the data processing unit that is used for the comparison monitor signal and predetermines the signal behind AD conversion unit, be connected with for remote communication's data communication unit behind the data processing unit respectively and be used for controlling the control the execution unit whether oil pump was opened and close, control execution unit put in series between oil pump and the oily pump power, AD conversion unit, the data processing unit all links to each other with the power module circuit with control execution unit. This application can realize the real -time supervision of transformer oil position to can realize teletransmission, the safety and stability nature of transformer operation is improved because of ambient temperature's change leads to the oil level abnormal conditions to the avoiding of the device maximum possible, guarantees the reliable power supply of electric wire netting.
Description
Technical field
The application belongs to and relates to a kind of monitoring automatically, and the transformer oil level automatically transformer oil storage supplemented is monitored and intelligent regulating device.
Background technology
Oil-immersed power transformer is higher at summer temp or extremely trembles with fear under weather condition winter, there will be the situation that oil conservater oil level is too high or too low, it is big that the reason first causing this phenomenon is because variation of ambient temperature, second is because transformer pouring oil mass not tight for control, oil level deviation " oil level-temperature " is caused by curve is excessive, 3rd is because some transformers exists leakage of oil situation, it is too low that long-term seepage also results in oil level, and the 4th is because transformator regularly draws oil sample and cause that internal oil mass gradually decreases.
When too high or too low warning occurs in oil level, producing the safe operation of transformator to threaten greatly, maintainer must drain the oil immediately or supplementary oiling processes, and causes that transformer oil storage damages or internal discharge fault as place not in time is comprehended.
Summary of the invention
The purpose of the application is in that to propose the transformer oil level monitoring of oil level in a kind of timely adjustment oil conservater and intelligent regulating device.
The purpose of the application is achieved in that transformer oil level monitoring and intelligent regulating device include monitoring the fuel level sensor of oil level change, fuel level sensor is connected with AD conversion unit circuit, after AD conversion unit, it is connected to compare the data processing unit of monitor signal and preset signals, the data communication units in order to telecommunication and the control performance element whether opened and closed in order to control oil pump it is connected to after data processing unit, control performance element series connection and access between oil pump and oil pump power supply, AD conversion unit, data processing unit is all connected with power module circuitry with controlling performance element.
Owing to implementing technique scheme, the application can realize the real-time monitoring of transformer oil level, and can realize remote transmission, and operation maintenance personnel just may browse through hundreds before computer and spreads over the transformer oil level situation in each corner, city; Moreover, the relation of this device shape always according to transformer oil storage and oil reserve, calculate current oil level and desirable oil level deviation, the meeting alarm when deviation reaches setting value, remind maintainer to note process of draining the oil in time, and can remind staff that oil level is adjusted to optimum position in note drains the oil process, maximum possible avoid because the change of ambient temperature causes oil level abnormal conditions, improve the security and stability that transformator runs, it is ensured that the reliable power supply of electrical network.
Accompanying drawing explanation
Accompanying drawing illustrates: the concrete structure of the application is provided by following drawings and Examples:
Fig. 1 is transformer oil level monitoring and intelligent regulating device structural representation.
Detailed description of the invention
Detailed description of the invention: the application, not by the restriction of following embodiment, can determine specific embodiment according to the technical scheme of the application and practical situation.
Embodiment: as shown in Figure 1, transformer oil level monitoring and intelligent regulating device include the fuel level sensor monitoring oil level change, fuel level sensor is connected with AD conversion unit circuit, after AD conversion unit, it is connected to compare the data processing unit of monitor signal and preset signals, it is connected to the data communication units in order to telecommunication and the control performance element whether opened and closed in order to control oil pump after data processing unit, controls performance element series connection and access between oil pump and oil pump power supply. AD conversion unit, data processing unit are all connected with power module circuitry with control performance element.
Described fuel level sensor exports the linear resistance of 0 ~ 190 ohm according to the height of oil level.
Described AD conversion unit includes bleeder circuit and analog-digital converter, and AD conversion unit converts the resistance that fuel level sensor exports to voltage signal, is converted further into digital signal, receives in order to data processing unit.
Described data processing unit obtains digital information from AD conversion unit, oil level height is calculated according to digital information, and make comparisons with " oil level-temperature " curve preset in it, if result of the comparison is beyond the alarming value set, then output alarm command and oil pump open command.
Described control performance element receives the instruction that data process, it is achieved the break-make of sound and light alarm and oil pump power supply, and then controls the volume that note is drained the oil, it is achieved being precisely controlled of oil level. Described control performance element includes sound light alarming circuit and electromagnetic valve, and electromagnetic valve series connection accesses between oil pump and oil pump power supply. Described sound light alarming circuit is prior art, and its physical circuit is not described in detail at this.
The oil level information that data processing unit is calculated by described data communication units is transferred to the formulation computer of LAN by certain communication protocol, and this computer can realize the remote real time monitoring of some transformer oil levels.
Ripple factor is little, harmonic wave is little, export stable power supply for unit offer for described power module, provides safeguard to the stable operation of each unit.
Above technical characteristic is only embodiments herein, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
