Background technology
At present, in each tame transformer station, all adopted high-voltage parallel dipping capacitor one time, and the paper insulation that this kind dipping capacitor is flooded, maximum allowable temperature is 90～95 ℃.But capacitor interior media hottest spot temperature in servicely but can't be monitored, and therefore can only come the temperature rise of indirect monitors internal hottest point from the temperature of shell.General capacitor allows the shell maximum temperature, oil impregnatedly is defined as 60 ℃, the chlorinated biphenyl dipping be defined as 80 ℃.
Yet in actual use work, if behind the capacitor seepage oil, pasta descends, and oil mass reduces; Moisture and moisture enter, and dielectric strength descends.When pasta downtakes to a certain degree the time, pasta is exposed in inner lead and element upper end, and causes extremely to discharge of case shell or component breakdown.Also have that operating ambient temperature is too high, superpotential etc. all might be caused capacitor explosion fault.The capacitor explosion often causes many, whole group capacitor damage simultaneously, even causes fire, and whole capacitor device chamber is burnt.Influence the operation of electricity net safety stable.
And the measure that prevents the capacitor explosion under the prior art has:
1. reinforcement equipment is maked an inspection tour, and manual observation capacitor appearance is seen to have or not and expanded and oil seepage phenomena.
But depend patrolman's visual detection alone, also can only only judge, can't learn inner case, so this kind detection mode is very inaccurate from the capacitor appearance.
2. with apparatus measures capacitor temperature, prevent that temperature from raising.
But all in capacitor panel, view window reflective infrared is again measured ripple for the cabinet type capacitor group of existing type, each capacitor, so can not arrive the temperature of each capacitor with apparatus measures.
To sum up, the various detection meanss under the prior art all can't detect the temperature of capacitor timely and effectively, bring hidden danger to equipment safety operation.
So press for a kind of novel capacitor temperature measuring equipment at present, need meet the following conditions:
1, this apparatus cost is not high, and cost of manufacture can descend in a large number.
2, this device need satisfy the explosion-proof needs of substation safety, and is nonflammable.
3, this device does not need external power source, present situation that can the practical work displays temperature.
4, this device needs installation, convenient fixing.
The utility model content
In order to solve the variety of problems that detects the problem of capacitor under the prior art, in conjunction with above-mentioned actual user demand, the utility model provides a kind of capacitor temperature detection device, when satisfying above-mentioned condition, can measure the temperature of capacitor effectively, concrete structure of the present utility model is as described below:
A kind of capacitor temperature detection device comprises a shell, it is characterized in that:
Described shell is the oblate disc-shaped housings of radius 25～30MM, and the shell face of one end designs for transparent mode, and the shell face of the other end is connected with a contact base, and enclosure is a sealed construction;
Be provided with a probe assembly in the described shell.
She Ji purpose is herein, shell is the oblate disc-shaped housings of 25～30MM, this becomes housing as the transcalent copper of employing, the shell face of one end is that transparent organic glass is made, be used for observed reading, this transparent shell face is oriented the direction of observing near easily, and the shell face of the other end is connected with the contact base, this contact base is bonded at the top of single capacitor by the stickup heat conductive silica gel, promptly equal whole capacitor actuator temperature sniffer is adhered on the single capacitor, and the degree of accuracy in order to measure prevents that humidity from causing that measurement is inaccurate, so whole casing inside is sealed construction.
According to a kind of capacitor temperature detection device of the present utility model, it is characterized in that, described probe assembly comprises spiral web-like composite bed sheet metal, sheet metal coupling shaft, pointer and temperature scale dish, it is specially spiral web-like composite bed sheet metal, one end of its helical coil is fixed on the inside that shell shell face connects the housing parts of contact base position, the other end is connected with pointer by the sheet metal coupling shaft, pointer cooperates with the temperature scale dish, and the temperature scale dish then is arranged at the inside of housing parts at the transparent area place of shell shell face.
She Ji purpose is herein, spiral web-like composite bed sheet metal is with golden, multiple metal film stack such as the platinum composition that forces together, measure sensitivity for improving, so sheet metal is manufactured the helical coil shape, and improved by the capacitor temperature and when changing shape when spiral web-like composite bed sheet metal, each layer expansion of metal or amount of contraction do not wait, make the spiral web-like composite bed sheet metal of helical coil shape roll or unclamp, because an end of the spiral web-like composite bed sheet metal of helical coil shape is fixed on the inside that shell shell face connects the housing parts of contact base position, and the other end links to each other with a pointer that can freely rotate by the sheet metal coupling shaft, therefore, experience temperature variation when sheet metal and roll or when unclamping, pointer can rotate on the scale of the temperature inside index dial of the housing parts at the transparent area place that is arranged at shell shell face, and this moment, the testing staff can observe the temperature data of capacitor intuitively.
Use capacitor temperature detection device of the present utility model to obtain following beneficial effect:
1. capacitor temperature detection device of the present utility model uses metal construction, and product are simple in structure, and after a large amount of the manufacturing, cost of products easily descends.
2. this becomes the housing of capacitor temperature detection device of the present utility model as the transcalent copper of employing, and inner sealing, is not subject to external environmental interference so measure temperature, and has saved the work of operation maintenance at ordinary times without external power source.
3. capacitor temperature detection device of the present utility model only needs the contact base is bonded at the top of single capacitor by pasting heat conductive silica gel, promptly equals whole capacitor actuator temperature sniffer is adhered on the single capacitor, install simple, convenient.
