Embodiment
Referring to figs. 1 through Fig. 5, the utility model fuse switch embodiment is described further.
Indoor vacuum circuit breaker control device, comprises housing 1, is provided with circuit board 2 in described housing 1, and described circuit board 2 is provided with relay 34, wherein:
Described circuit board 2 is fixedly installed mount pad 4, and the bottom of described relay 34 is provided with buckle 8, and the bottom of described mount pad 4 offers the jack 9 coordinated with buckle 8, and as shown in Figure of description 2, described relay 34 is plugged in described mount pad 4;
Described mount pad 4 is provided with bimetal leaf 5, should be noted that: bimetal leaf 5 also claims thrermostatic bimetal-plate 5, because the thermal coefficient of expansion of each constituent element layer is different, when the temperature is changed, the deformation of active layers 51 is greater than the deformation of passive layer 52, thus the entirety of bimetal leaf 5 will to passive layer 52 curving, then the curvature of this composite material changes thus produces deformation.Wherein, what the coefficient of expansion was higher is called active layers 51; What the coefficient of expansion was lower is called passive layer 52, but along with the expansion of bimetallic application and the progress of combination technology, occurs the bimetallic of three layers, four layers, five layers modern age mutually.In fact, every temperature dependent changes and the combined material of change of shape occurs, and is still being called thermo bimetal traditionally now.
In the present embodiment; the preset temperature of described bimetal leaf 5 is preferably at 70 DEG C ~ 80 DEG C; when described relay 34 temperature exceedes the preset temperature of bimetal leaf 5; active layers 51 in described bimetal leaf 5 produces distortion; thus described relay 34 is released described mount pad 4; thus protection relay 34, avoid relay 34 because of overheated and scaling loss.
It should be noted that, in the present embodiment, can following scheme be preferably set, all electric conducting material is provided with in described active layers 51 and passive layer 52, active layers 51 in the contact of the bottom of described relay 34 and bimetal leaf 5 is conflicted, described active layers 51 is then pressed down by relay 34 and contacts with passive layer 52, described passive layer 52 is electrically connected with circuit board 2, scheme replaces simple active layers 51 to press close to bottom relay 34 arranging thus, described active layers 51 temperature of monitoring will more accurately, reaction is more timely.
Further, between described relay 34 and mount pad 4, be also fixedly installed intercell connector 7, when described relay 34 comes off because of overheated from mount pad 4, still have connecting line to connect, avoid relay 34 fall from eminence and break.
Shown in Figure of description 2, described bimetal leaf 5 is preferably arranged on the bottom of described mount pad 4, when described bimetal leaf 5 produces distortion, its active force produced relay 34 is identical with the opening direction of mount pad 4, makes described bimetal leaf 5 more described relay 34 can be released mount pad 4.
The side of described mount pad 4 is provided with elastic component 6, is recommended as spring.Described elastic component 6 is conflicted with relay 34, as as described in Figure of description 3, when relay 34 is plugged in mount pad 4, described spring compression relay 34, its auxiliary fixing effect, and when described relay 34 departs from mount pad 4, frictional force is there is between described elastic component 6 and relay 34, thus described elastic component 6 can produce deflection, thus described elastic component 6 apply towards mount pad 4 opening direction elastic force to mount pad 4, thus accelerate it and come off the time, improve its opening speed thus ensure the safety of relay 34.
It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
