During a work process of a compressor, through the additionally-arranged heat protection device, purposes of protection on the capacitor and improvement of use safety performance of the compressor are realized, so problems of failure of a capacitor product and influence on normal use of the compressor caused by temperature rising are avoided.
Description
Technical field
The utility model belongs to the technical field of electric elements structure.Specifically, the utility model relates to a kind of electrolytic capacitor starting guard equipment.
Background technology
Compressor electric motor, in the moment of starting, by discharging and recharging of electric capacity, increases starting torque; At compressor operation proceed-to-send, enter normal operation after, electric capacity must be disconnected.
The disconnect mode of capacitor has speed relay, delay-time protector of Weight type etc.These two kinds of disconnect modes all adopt contact switch.In contact switch when work,, often there will be the phenomenons such as riveted, bonding, arc welding, causes electric capacity power-off in time; Be that capacitor is after compressor normal starting, cannot normally disconnect, consequently electric current increases, capacitor internal temperature raises, electrolyte gasification, interior voltage rise are high, causes capacitor from explosion valve to be opened, and then causes that capacitor lost efficacy, compressor cannot normal starting.
The inefficacy of capacitor product, by affecting the normal use of compressor, even causes the damage of compressor auxiliary winding.
Summary of the invention
The utility model provides a kind of electrolytic capacitor starting guard equipment, its objective is the usage safety performance of capacitor for voltage protection and raising compressor.
To achieve these goals, the technical scheme that the utility model is taked is:
Electrolytic capacitor starting guard equipment of the present utility model, described electrolytic capacitor comprises that capacitor cover plate, core bag main body and two lead paper tinsel, the described paper tinsel of leading is connected with the two poles of the earth in core bag main body respectively; Lead serial connection on paper tinsel thermel protection device is set for therein one.
Described thermel protection device is the temperature relay as temperature sensitive member and switch element by thermometal sheet.
Described thermometal sheet is the bimetal leaf that thermal coefficient of expansion does not wait, and by its superimposed connection, as described temperature sensitive member and switch element.
Described electrolytic capacitor is aluminium electrolytic capacitor.
Described capacitor cover plate is rubber layer pressing plate.
On described capacitor cover plate, be provided with two weld tabs, described two weld tabs are respectively led paper tinsel and are connected with one.
The utility model adopts the beneficial effect of technique scheme:
In compressor operation, by increasing thermel protection device, reach the object of the usage safety performance of capacitor for voltage protection and raising compressor; When temperature is increased to rated temperature, thermometal sheet is heated and produces internal stress and disconnection rapidly, cuts off circuit, thereby plays heat protective effect; When capacitor internal drops to specified reset temperature, recover normal operating conditions; Avoid capacitor after compressor normal starting, cannot normally disconnect, cause that capacitor internal temperature raises, electrolyte gasification, interior voltage rise be high, until capacitor from explosion valve opens, the normal phenomenon of using of capacitor product failure effect compressor.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure, be labeled as:
1, capacitor cover plate, 2, core bag main body, 3, lead paper tinsel, 4, thermel protection device, 5, weld tabs.
Embodiment
Structure of the present utility model as shown in Figure 1, is electrolytic capacitor starting guard equipment, mainly plays superheat protecting function.The utility model is specially adapted in compressor, the ancillary apparatus element during as starting.
This electrolytic capacitor comprises that capacitor cover plate 1, core bag main body 2 and two lead paper tinsel 3, and the described paper tinsel 3 of leading is connected with the two poles of the earth in core bag main body 2 respectively.The purpose of this utility model is that after solving compressor start, capacitor cannot normally disconnect, capacitor and occur that electric current increases, internal temperature raises, electrolyte gasification, interior voltage rise be high, cause capacitor from explosion valve to be opened, capacitor product lost efficacy and affected the normal problem of using of compressor.
Electrolytic capacitor of the present utility model refers in particular to aluminium electrolytic capacitor.
Wherein, described capacitor cover plate 1 is rubber layer pressing plate.Rubber layer pressing plate plays the effect of sealing, protective core bag main body and insulation.
The circuit of aluminium electrolytic capacitor of the present utility model in the following ways, as binding post:
As shown in Figure 1, be provided with two weld tabs 5 on described capacitor cover plate 1, described two weld tabs 5 are respectively led paper tinsel 3 and are connected with one.
In order to solve the problem of prior art existence and to overcome its defect, realize the goal of the invention of the usage safety performance of capacitor for voltage protection and raising compressor, the technical scheme that the utility model is taked is:
As shown in Figure 1, electrolytic capacitor starting guard equipment of the present utility model, on existing circuit base, also two one of them that lead in paper tinsel 3, serial connection arranges thermel protection device 4.
In the course of work of compressor electric motor, by this thermel protection device, the disconnection that realizes capacitor be connected, reach capacitor for voltage protection and improve the object of the usage safety performance of compressor.
Described thermel protection device 4 be when high temperature by circuit disconnect, temperature decline after make circuit Power resumption electrical equipment; the mode of taking is: described thermel protection device 4 is the temperature electrical equipment as temperature-sensing element and switch element by thermometal sheet, or is called thermal relay.
When temperature is increased to rated temperature, thermometal sheet is heated and produces internal stress and disconnection rapidly, cuts off circuit, thereby plays heat protective effect.
When capacitor internal drops to specified reset temperature, thermometal sheet recover normal operating conditions, even circuit turn-on, recover normal power-up.
The set-up mode of concrete thermometal sheet is:
Described thermometal sheet is the bimetal leaf that thermal coefficient of expansion does not wait, and by its superimposed connection, as described temperature sensitive member and switch element.The method of its protection is:
Under the condition not yet raise in temperature, temperature rise distortion not occurring bimetal leaf, the switch element that bimetal leaf forms, in closure state, makes circuit turn-on, and at this moment, the break-make of capacitor is by the control of normal capacitor control apparatus;
Once fault that normal control apparatus generation contact cannot disconnect occur, causing the undesired rising of temperature, due to its different thermal coefficient of expansion, there is warpage in bimetal leaf; the direction of its buckling deformation; be to make switch element in off-state, finally make circuit disconnect, realize circuit protection.
Below by reference to the accompanying drawings the utility model is exemplarily described.Obviously, the utility model specific implementation is not subject to the restrictions described above.As long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out, or without improvement, design of the present utility model and technical scheme are directly applied to other occasion, all within protection range of the present utility model.
