Abstract
An oil-immersed controlling or protecting electric device is composed of enclosed shell, electric device, heat radiator and electric insulating oil. The electric device is installed in shell full of electric insulating oil. The heat radiator is attached to shell. As the device is immesed in insulating oil, spark can not be generated when its contacts work. The heat generated by electric device can be effectively radiated out. Its advantages are improving performance of electric device, elongating service life of electric device, and simple structure.
Description
The invention relates to a kind of control of in electrical apparatus insulation oil, working, protection electrical equipment.
General control, protection electrical equipment are to work in the environment of air, contact in control, the protection electrical equipment closed, can produce spark when disconnecting, the high temperature that spark produces has bigger damage to the contact, has directly influenced the useful life of control, protection electrical equipment.Control, the heat that produces at work of protection electrical equipment dispel the heat in air, because the thermal conductivity of air is not strong, often make some the parts temperature rises in control, the protection electrical equipment higher, also influenced control, have protected useful life of electrical equipment.
The object of the present invention is to provide a kind of oil immersed type control, protection electrical equipment, the spark that this electrical equipment can be eliminated control, protect appliance contact to be produced when work, and make control, protection electrical equipment can obtain more effective heat radiation.
Technical scheme of the present invention: control, protection electrical equipment are inserted in totally-enclosed housing; in housing, annotated enough electrical apparatus insulation oil; make control, protection electrical equipment in electrical apparatus insulation oil, work fully; fin is housed outside housing, and fin is directed at housing with the temperature of electrical apparatus insulation oil and dispels the heat outward.
A kind of totally enclosed housing; control, protection electrical equipment are installed in the housing inner bottom part; annotate sufficient electrical apparatus insulation oil in the housing; the oil reservoir face of electrical apparatus insulation oil is in housing on the higher position; make control, protection electrical equipment be in fully and carry out work in the insulating oil, the contact of control, protection electrical equipment is immersed in the insulating oil and just can produce spark when work.Fin is housed on housing, and fin is compressed on the housing.Being heated of fin partly contacts with insulating oil in housing, the heat radiation that the temperature of insulating oil is directed at the outer fin of housing is partly dispelled the heat, because the thermal conductivity height of insulating oil, the fin volume is big, makes electrical equipment can access the heat radiation of more imitating and has reduced working temperature.Axle on the electrical equipment of control, protection, button by housing from the housing to housing the time, all put oil-resistant rubber insert, oil-proof to reach housing seal.Be provided with the air vent hole of perforation on the housing in housing above the oil reservoir face of electrical apparatus insulation oil.
In sum; the present invention adopts the design of control, protection electrical equipment oil immersed type, makes appliance contact can not produce spark, and the electrical work temperature obtains fine cooling; improve the service behaviour of control, protection electrical equipment, improved useful life of control, protection electrical equipment.The utlity model has economical and practical, simple in structure, be suitable for advantages such as popularization.
Below in conjunction with drawings and Examples technology contents of the present invention is described further.

The control of embodiment 1 oil immersed type, protection electrical equipment
Among Fig. 1, Fig. 2; control, protection electrical equipment (2) are installed in the interior bottom of housing (1) of sealing; annotated foot electrical apparatus insulation oil (3) in the housing (1), made the oil reservoir face of electrical apparatus insulation oil in housing on the higher position, control, protection electrical equipment are immersed in the insulating oil fully.Axle (6) on the electrical equipment (2), button (7) all put oil resistant rubber sealing gasket (5) by housing (1) time, oil-resistant rubber insert (5) is installed on the housing (1) by pressing plate (14), and be oil-proof to guarantee housing (1).The binding post (13) of housing (1) is compressed on the housing (1), and electrical equipment (2) is connected by the binding post (13) on the housing (1) and power supply, signal.In housing, be provided with the air vent hole (18) of perforation on oil reservoir face (17) upper shell of electrical apparatus insulation oil.Being heated of fin (4) partly contacts with insulating oil (3), and partly dispels the heat to the heat radiation of the outer fin of housing (1) (4) the temperature rise conduction in time of electrical equipment (2).Owing to having annotated foot in the housing (1) electrical equipment slow extremely oily (3), control, protection electrical equipment (2) contact are immersed in the insulating oil and can not produce spark when work; The radiating effect that insulating oil (3) and fin (4) are produced is better; each position of control, protection electrical equipment (2) is immersed in the insulating oil; temperature rise is reduced, and makes the service behaviour of control, protection electrical equipment (2) be improved, and helps the useful life of control, protection electrical equipment (2).
Established oily window on embodiment 2 controls, the protection electric appliance casing
Among Fig. 3, have the oily window of mistake (8) of perforation on control, protection electrical equipment (2) shell, carry out efficiently radiates heat by insulating oil (3), fin (4) in order to electrical equipment (2) temperature rise.
The fin of embodiment 3 band inner chambers
Among Fig. 4, fin (4) is provided with inner chamber (9), helps the raising of radiating effect.
Among Fig. 5, be provided with oil inlet pipe (10), flowline (11) on housing (1), insulating oil (3) inside and outside the flowing of circulating of housing (1), helps the reduction of control, the temperature rise of protection electrical equipment (2) under the drive of oil pump.In housing (2), also be provided with temperature inductor (12), so that the temperature of insulating oil (3) is monitored.
Oil immersed type control, the protection electrical equipment of embodiment 5 band pressure switches
Among Fig. 6, housing (1) is provided with the force pipe (15) of perforation, and force pipe (15) one ends communicate with insulating oil (3), and the other end communicates with pressure switch (16).The effect of force pipe (15) is: when electrical equipment (2) when being in abnormal work temperature sharply rise; pressure in the closure casing (1) increases thereupon; to pressure switch (16) generation effect, pressure switch (16) carries out work control, protection electrical equipment (2) is carried out monitoring this pressure by force pipe (15).
