Abstract
The utility model discloses an online absolute oil control device of a transformer, which comprises a LOGO controller, an air switch QA, an AC contactor KM, a DC power supply GKD and an oil pump motor M1, wherein the power supply is connected with the input end of the air switch QA, the air switch QA and the AC contactor KM are connected in series and then connected to the oil pump motor M1, the coil of the AC contactor KM is connected on the control end of the LOGO controller, and the output end of the DC power supply GKD is connected with the power input end of the LOGO controller. The online absolute oil control device is based on the design of the LOGO controller and the contactor, and has the advantages of high efficiency and convenient control.
Description
Technical field
The utility model relates to a kind of transformer on-line oil cleaning control device.
Background technology
Existing transformer on-line oil cleaning control device adopts the control of traditional relay, and in addition, existing transformer on-line oil cleaning control device adopts traditional switching value and controls with fixing control mode, so efficient is low, weak effect.
The utility model content
In order to solve the above-mentioned technical problem that existing transformer on-line oil cleaning control device exists, the utility model provide a kind of simple in structure, efficient is higher, control transformer on-line oil cleaning control device easily.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: comprise LOGO! Controller, air switch QA, A.C. contactor KM, DC power supply GKD, Oil pump electrical machinery M1, power supply connects the input of air switch QA, air switch QA, A.C. contactor KM the series connection after receive Oil pump electrical machinery M1, the coil of A.C. contactor KM be connected on LOGO! Control end on, the output of DC power supply GKD termination The power input of controller.
In the above-mentioned transformer on-line oil cleaning control device, also comprise air switch QA1, temperature and humidity controller WSK1, heating resistor HE, fan electromotor M, plugging relay PH1, the input of described A.C. contactor KM is taken over control and is reversed relay PH1, and air switch QA1, temperature and humidity controller WSK1, heating resistor HE, fan electromotor M form the temperature control loop.
Technique effect of the present utility model is: 1) the utility model adopt Siemens LOGO! Controller forms a whole the parts of whole on-line oil cleaning control device, has the efficient height, the advantage that control is convenient, control is effective.2) Siemens LOGO! Controller has manually, automatically, functions such as regularly startup, operating time setting; And have action frequency record, safeguard multiple functions such as warning; Also dispose the temperature control loop, when temperature was lower than 5 ℃ or humidity and reaches 80%, heater was started working, and when temperature reached 45 ℃, fan was started working, so just guaranteed device can be under multiple environment operate as normal, realize that round-the-clock no worker monitor works automatically.
