Description
Technical field
The utility model relates to mechanical equipment technical fields, and in particular to one kind is filled for plate-frame-type oil-filtering machine heated at constant temperature
It sets.
Background technique
Plate-frame-type oil-filtering machine is for transformer oil filtering to be recycled a kind of equipment, main function in bargh
It is by the granule foreign filtering cleaning in transformer oil.The shortcomings that prior art/deficiency: existing frame type oil filter is in filtering transformation
During device oil, the contaminant filter in transformer oil is cleared up in a manner of constantly recycling, but is unable in eliminating transformer oil
Moisture makes to recycle by pressure test through the filtered transformer oil of oil filter, and wastes a large amount of transformations
Device oil, increases the cost of to maintain equipment.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts, it is simple to provide a kind of improvement structure, is modified to
This is low, energy-saving and environment-friendly for plate-frame-type oil-filtering machine constant temperature heating device.
The utility model is achieved through the following technical solutions:
One kind being used for plate-frame-type oil-filtering machine constant temperature heating device, including oil tank of transformer, heating plate, thermostatically-controlled equipment；
The oil tank of transformer is connect by oil inlet pipe and flowline with plate-frame-type oil-filtering machine, and the heating plate is mounted on transformer
The inside of fuel tank；The thermostatically-controlled equipment includes temp probe, temperature controller, contact-making switch, time controller；It is described
Oil tank of transformer inside and be electrically connected with temperature controller, the temperature controller, time controller and heating plate point
It is not electrically connected with contact-making switch；The temp probe passes through the temperature inside detection oil tank of transformer and is converted into electric signal hair
It send to temperature controller, temperature controller is by judging whether temperature exceeds limit value to control heating plate by contact-making switch
On-off；The time controller controls the on-off of heating plate by the setting working time and by contact-making switch.
As an improvement of the above scheme, the temp probe is thrust-type thermocouple.
As an improvement of the above scheme, the thermostatically controlled temp set temperature is 70 DEG C.
As an improvement of the above scheme, the time controller setting time is 2 hours.
The utility model has the following beneficial effects:
1. the prior art does not have a fuel reserve tank constant temperature heating device in frame type oil filter, oil strain mode be " fuel reserve tank →
Oil pump → filter cloth → fuel reserve tank " transform that " " fuel reserve tank heated at constant temperature → fuel reserve tank → oil pump → filter cloth → fuel reserve tank constant temperature adds as
Heat ", transformer oil is heated to 70 degrees Celsius in fuel reserve tank by constant temperature heating device, recycles transformer oil in frame type oil filter
The continuous extra moisture of evaporation, the device play the role of heating evaporation moisture in filtering.
2. installation, easy to operate, stable.Structurally reasonable, failure rate is low, and maintenance is simple, and heating time can be according to useless
Old transformer impurity moisture is controllable.
3. frame type oil filter is after installing heated at constant temperature, waste and old transformer oil moisture energy rapid evaporation, filtered transformation
Device oil can be reached by pressure test using standard, cycling and reutilization.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the constant temperature heating device of the utility model.
Description of symbols: oil tank of transformer 1, heating plate 2, thermostatically-controlled equipment 3, oil inlet pipe 4, flowline 5, plate and frame
Oil filter 6, temp probe 7, temperature controller 8, contact-making switch 9, time controller 10.
Specific embodiment
Embodiment
As shown in Figure 1, a kind of be used for plate-frame-type oil-filtering machine constant temperature heating device, including oil tank of transformer 1, heating plate 2, perseverance
Temperature control device 3；The oil tank of transformer 1 is connect by oil inlet pipe 4 and flowline 5 with plate-frame-type oil-filtering machine 6, and described adds
Hot plate 2 is mounted on the inside of oil tank of transformer 1；The thermostatically-controlled equipment 3 includes temp probe 7, temperature controller 8, connects
Touch switch 9, time controller 10；It the inside of the oil tank of transformer 1 and is electrically connected with temperature controller 8, the temperature
Controller 8, time controller 10 and heating plate 2 are electrically connected with contact-making switch 9 respectively；The temp probe 7 is become by detection
Temperature inside depressor fuel tank 1 is simultaneously converted into electric signal and is sent to temperature controller 8, and temperature controller 8 is by judging temperature
The no on-off for controlling heating plate 2 by contact-making switch 9 beyond limit value；The time controller 10 passes through setting work
Time and the on-off that heating plate 2 is controlled by contact-making switch 9.The temp probe 7 is thrust-type thermocouple.The constant temperature
Controlling temperature set temperature is 70 DEG C.10 setting time of time controller is 2 hours.
Above-listed detailed description is illustrating for the utility model possible embodiments, and the embodiment is not to limit
The scope of the patents of the utility model, all equivalence enforcements or change without departing from carried out by the utility model, is intended to be limited solely by this case
