Abstract
The utility model relates to a drawer type breaker heating device, which comprises radiating fins and a heating plate with a groove. A drawer type heating element is arranged inside the groove of the heating plate. The heating element is formed by making an aluminum coating packaged on the outer part of a silicone rubber electrothermal module. The drawer type breaker heating device has the characteristics of easy replacement and convenient maintenance. Comprehensively speaking, the drawer type breaker heating device achieves the most stable heating effects.
Description
Technical field
The utility model relates to a kind of heating apparatus, relates in particular to withdrawable circuit breaker heating apparatus in a kind of 66kV and the above breaker mechanism case, belongs to the electric power application.
Background technology
The north of china in winter cold weather needs to rely on heating apparatus to come hoisting mechanism the temperature inside the box to run well to guarantee breaker mechanism in the breaker mechanism case.Now all adopt 100W flat aluminium alloy plate heater heating plate in a lot of regional breaker mechanism casees; the inner resistance wire that adopts of this type heating plate; the logical 220V voltage in two ends makes resistance wire generate heat to hoisting mechanism the temperature inside the box, but heat regular meeting will make the resistance wire fracture that heating system is damaged because can not distributing.And do not have the indicating device that clearly reflects operating state, and in running, be difficult for being discovered, can't finish reparation.Heating plate is changed 121 because of such accident in certain electric company's breaker mechanism in 2011, changes 134 of such electric hot plates because of such accident in 2012, so how to improve the problem that such electric hot plate becomes current urgent solution.
Summary of the invention
The utility model according to the good characteristic of silicon rubber electrothermal module, by adding thermal effect relatively, provides a kind of withdrawable circuit breaker heating apparatus at above-mentioned problems of the prior art, has solved the flimsy problem of heating apparatus in the prior art.
The technical solution of the utility model is as follows:
Comprise the heating plate of fin and band groove, the drawer type heating element is set in the heating plate groove, described heating element is the outer packaging aluminium coating of silicon rubber electrothermal module.
Described aluminium coating is provided with groove, and the nichrome resistance wire is arranged in the groove.
The bottom installment work status indicator lamp of described heating element.
The utility model has the advantages of as follows:
1, the silicon rubber electrothermal module has excellent physical strength and softness, and electric heating element is well contacted with heating object.
2, the silicon rubber electrothermal module can be designed to different shape.
3, the silicon rubber electrothermal module is in light weight, thickness as thin as a wafer, thermal capacity is little, can reach the very fast rate of heat addition.
4, Jing Mi metal electric heating membrane circuit can further improve the surface power density of silicon rubber heating element, improves the uniformity of surperficial heating power, increases the service life and has good handling.
5, silicon rubber has good weatherability and ageing resistance, can effectively prevent product surface cracking and enhance mechanical strength as the surface insulation material of Electric radiant Heating Film, has prolonged the useful life of product greatly;
6, the silicon rubber electrothermal module has good resistance to chemical attack, is used for the more abominable places of environment such as humidity, corrosive gas.
7, easy for installation.
The scald accident takes place in 8, the correct indicating operating status of indicator light when preventing from checking heating plate.

Fig. 1 is structure cross-sectional schematic of the present utility model.
Fig. 2 is internal structure schematic diagram of the present utility model.
Fig. 3 is polycrystalline substance schematic diagram of the present utility model.
Among the figure, 1, fin, 2, the silicon rubber electrothermal module, 3, the aluminium coating, 4, the nichrome resistance wire, 5, indicator light, 6, AC220V, 7, fixed head.
Embodiment
With reference to accompanying drawing, in conjunction with specific embodiments, it is as follows that the utility model is elaborated.
Embodiment
As Figure 1-3, comprise the heating plate of fin 1 and band groove, the drawer type heating element is set in the heating plate groove, described heating element is the outer packaging aluminium coating 3 of silicon rubber electrothermal module 2; Aluminium coating 3 is provided with groove, and nichrome resistance wire 4 is arranged in the groove.The bottom installment work status indicator lamp 5 of described heating element.
Described nichrome resistance wire is replaceable to be metal forming.
The utility model adopts-60 ℃～250 ℃ high-low temperature resistants, conductive coefficients to reach 0.83 the silicon rubber that high heat conduction, insulation property are good, intensity is good and resistant to elevated temperatures fibre reinforced materials and nichrome resistance wire or gathers the soft electric heating film element that forms with metal forming heating film circuit; Be installed in 66kV and the above breaker mechanism case, observe heating effect.
Installation drawer type silicon rubber heating module in the 220kV triumph 220kV of transformer station bus mechanism case since on November 30th, 2012 test being installed, has been controlled at 20 ℃ with the thermometer test in this breaker mechanism case, the circuit breaker catching phenomenon do not occur and takes place.
In the flat aluminium one line breaker mechanism case of the 220kV peace 66kV of transformer station, drawer type silicon rubber heating module is installed, since on December 13rd, 2012 test being installed, control at 20 ℃ with the thermometer test in this breaker mechanism case, the circuit breaker catching phenomenon do not occur and take place.
