Description
Technical field
The utility model relates to electrical equipment, particularly a kind of based Transformer forced oil wind cooling controller.
Background technology
Transformer utilizes the principle of electromagnetic induction to change the power equipment of alternating voltage, often causes own temperature to raise, thus need cooling controller to cool to transformer in the transformer course of work.
There is wiring complexity in the active air-cooled control system of existing electromagnetic type relay composition, accuracy of timekeeping is not high, components and parts easily aging, damage, the problems such as difficult in maintenance, and need operations staff manually to drop into and exit cooling fan and rotation operation, workload is large, there is the possibility causing error tripping accident due to the fault of air-cooled opertaing device own.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of based Transformer forced oil wind cooling controller, pass through Programmable Logic Controller, realize setting operational factor in advance, automatic input and exit cooling fan and rotation and run, and upload the operation conditions of air cooling system in real time, thorough solution human at periodic intervals operates control, alleviates the workload of operations staff, realizes full-automatic.
For achieving the above object, the utility model provides following technical scheme: a kind of based Transformer forced oil wind cooling controller, it is characterized in that: described based Transformer forced oil wind cooling controller comprises a housing, in housing, PLC is installed, and in housing, be respectively arranged with A.C. contactor, isolating switch, phase sequence open phase relay, refrigeratory, all be connected with PLC, surface of shell is provided with touch-screen and some communication interfaces, and is all connected with PLC.
Preferably, described housing and contents all form with the manufacture of stainless steel 1Cr18Ni9Ti material.
Preferably, described based Transformer forced oil wind cooling controller adopts the dual power supply that primary power and standby power supply match.
Preferably, described touch-screen is 5.7 inches of touch-screens.
Preferably, described refrigeratory connection control fan electromotor.
The beneficial effect of above technical scheme is adopted to be: the technical basis transformer operating standard requirement that this based Transformer forced oil wind cooling controller is advanced, pass through Programmable Logic Controller, solve the difficult problem do not solved recent decades, realize setting operational factor in advance, automatic input and exit cooling fan and rotation and run, safety, stable operation important in inhibiting reliable to main transformer.The active air-cooled control system wiring solving electromagnetic type relay composition is complicated, accuracy of timekeeping is not high, components and parts easily aging, damage, problem difficult in maintenance, ensure that power network safety operation, alleviate again the burden of operation, repair and maintenance personnel defect elimination, the fund decreasing accessory is propped up, and is subject to the extensive welcome of vast power transformation operation, maintainer.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the layout of a kind of based Transformer forced oil wind cooling controller of the utility model.
Wherein, 1-PLC, 2-touch-screen, 3-A.C. contactor, 4-isolating switch, 5-phase sequence open phase relay, 6-communication interface, 7-refrigeratory, 8-primary power, 9-standby power supply, 10-housing.
Embodiment
The preferred implementation of a kind of based Transformer forced oil wind cooling controller of the utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 shows the embodiment of a kind of based Transformer forced oil wind cooling controller of the utility model: this based Transformer forced oil wind cooling controller comprises a housing 10, PLC 1 is installed in housing 10, and in housing 10, be respectively arranged with A.C. contactor 3, isolating switch 4, phase sequence open phase relay 5, refrigeratory 7, all be connected with PLC 1, housing 10 surface is provided with touch-screen 2 and some communication interfaces 6, and is all connected with PLC 1.
Housing 10 and contents all form with the manufacture of stainless steel 1Cr18Ni9Ti material.The dual power supply that based Transformer forced oil wind cooling controller adopts primary power 8 and standby power supply 9 to match.Touch-screen 2 is 5.7 inches of touch-screens.Refrigeratory 7 connection control fan electromotor.
This device adopts PLC 1 as main control core, touch-screen 2 is as man-machine interface, A.C. contactor 3 is as power executive component, isolating switch 4, phase sequence open phase relay 5 is as protection element, by touch-screen 2, operational factor is set, drop into according to top-oil temperature and operating load signal and exit the refrigeratory 7 of corresponding modes, by operating failure message by communication interface 6 or the teletransmission of fault contact, finish message is stored in touch-screen 2 simultaneously, concrete failure cause can be found out by " fault analysis " option, time, also can timing automatic rotation work power supply and refrigeratory 7 operational mode.Achieve auto-control, status information, display and user-friendly for operation.
Operating transformer upper strata oil temperature is higher than 55 degree or the upper current relay action of tranformer protection screen, and " assisting " state refrigeratory puts into operation, and when temperature is down to 45 degree, the refrigeratory of " assisting " state is out of service.Any one group as " work " or " assisting " state in operation is broken down, and " for subsequent use " refrigeratory puts into operation, sends the distant signal of " Cooler Fault " simultaneously, shows defect content nearby.Repair fault, " for subsequent use " state refrigeratory is out of service, and fault-signal disappears, and preserves failure logging simultaneously.
Motor very easily causes " work " to organize fan electromotor bearing grease premature deterioration under operating in 60 DEG C ~ 70 DEG C environment temperatures, this group fan electromotor is caused often to burn, devise refrigeratory operational mode time in turn function for this reason, according to the time that touch-screen 2 is arranged, timing automatic rotation refrigeratory 7 operational mode, order often organizes refrigeratory alternate run in " work " pattern.
According to the requirement of transformer operating standard, pass through Programmable Logic Controller, realize setting operational factor in advance, automatic input and exit cooling fan and rotation and run, and upload the operation conditions of air cooling system in real time, thorough solution human at periodic intervals operates control, alleviates the workload of operations staff, realizes full-automatic.Utilize selection that is manual and automatic control mode, equipment is in operation safer relieved, if device occurs abnormal, system can transfer manual operation to automatically, fault-signal is uploaded simultaneously, guarantee the uninterrupted operation of transformer, air-cooled full cut-off can not be caused and affect operation, more can not because of being unattended station, can not be arrived in the very nick of time scene and cause transformer to burn or error tripping, avoid due to the fault of air-cooled opertaing device own and cause error tripping accident, on electrical network, having immeasurable impact to society.
Above is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
