Description
Technical field
The utility model is related to capacitance technology field more particularly to photovoltaic capacitances.
Background technology
Since photovoltaic electric container work frequency is higher, prodigious ripple and harmonic current are generated, capacitance fever is serious, simultaneously
Photovoltaic apparatus use environment inclement condition, works in high temperature and humidity for a long time, and the requirement to capacitor is harsher.So
It wants to use under the conditions of high temperature and humidity, it is necessary to have the features such as overcurrent capability is big, high pressure, long lifespan, to effectively
It is cost-effective.
Utility model content
In order to overcome the above problem existing for photovoltaic capacitor, the utility model to provide a kind of photovoltaic capacitance.
The utility model technical solution used for the above purpose is：A kind of photovoltaic capacitance, 4 upper table of capacitor core
Face is equipped with plated film pole plate, and 4 lower surface of capacitor core is equipped with metal spraying pole plate, and capacitor core is installed in shell 1, capacitor core 4 with
Filler is equipped between shell 1,4 top and bottom of capacitor core are Wave-cut face 5, and 1 upper end of shell is equipped with upper leading-out terminal
3,1 lower part of shell is equipped with lower leading-out terminal 2, the metal spraying pole plate of upper leading-out terminal 3 and lower leading-out terminal 2 connection capacitor core 4.
The filler is epoxy resin.
The photovoltaic capacitance of the utility model ensure that the stabilization and precision of capacity, and inductance value is low, and resistance to big electricity greatly improved
The intensity press, shoved, improves the insulating properties and capacity stability, reliability of service life of capacitor, and has good heat dissipation work(
Can, ensure that capacitor is run for a long time.
Description of the drawings
Fig. 1 is the utility model photovoltaic capacitance main view sectional structure chart.
Fig. 2 is the utility model photovoltaic capacitance external structure.
In figure：1, shell, 2, lower leading-out terminal, 3, upper leading-out terminal, 4, capacitor core, 5, Wave-cut face.
Specific implementation mode
The volt capacitance of the utility model is as depicted in figs. 1 and 2, and 4 upper surface of capacitor core is equipped with plated film pole plate, capacitor core
4 lower surfaces are equipped with metal spraying pole plate, and capacitor core is installed in shell 1, is filled out equipped with epoxy resin between capacitor core 4 and shell 1
Object is filled, 4 top and bottom of capacitor core are Wave-cut face 5, and 1 upper end of shell is equipped with upper leading-out terminal 3, and 1 lower part of shell is equipped with
Lower leading-out terminal 2, the metal spraying pole plate of upper leading-out terminal 3 and lower leading-out terminal 2 connection capacitor core 4.
Photovoltaic capacitance processing technology, includes the following steps：
A, capacitor core 4 is cut using Wave-cut technique；
B, the capacitor core 4 after cutting is put into shell 1, and asphalt mixtures modified by epoxy resin is filled between capacitor core 4 in shell 1
Fat.
Using Wave-cut technique, the contact surface of metal spraying part is made to increase.By testing in many ways, epoxy resin uses in addition
The material that Composite Double 85 requires passes through multi-party break-in with epoxy resin producer, and repetition test obtains 85 degree of combined temp, simultaneously
85 degree of humidification degree, degradation 1000 hours add 1.3 times of pressure resistance.It is long-term under the conditions of high temperature and humidity to reach photovoltaic electricity container
The index of normal operation.
The utility model is described by embodiment, and those skilled in the art know, new not departing from this practicality
In the case of the spirit and scope of type, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, at this
Under the introduction of utility model, it can modify to these features and embodiment to adapt to particular situation and material without taking off
Spirit and scope from the utility model.Therefore, the utility model is not limited to the particular embodiment disclosed, and is owned
The embodiment fallen within the scope of claims hereof belongs to the scope of protection of the utility model.
