Abstract
The invention discloses a capacitor with a built-in voltage-dividing resistor and the capability of being grounded, which comprises a housing, wherein an end cover is covered on the housing, terminals are arranged on the end cover, a capacitor core body is arranged in the housing, a grounding conducting wire is led out of a conducting wire between the capacitor core body and one terminal, a button switch is connected into the grounding conducting wire, and the resistor is connected into the conducting wire between the capacitor core body and the other terminal.
Description
Technical field
The present invention relates to electron electric power device field, but be specially a kind of ground capacity of built-in divider resistance.
Background technology
Electric capacity is one of a large amount of electronic components that use in the electronic equipment, is widely used in every aspects such as straight, coupling, bypass, filtering, resonant tank, power conversion, control circuits.Electric capacity is to be made of any two insulated from each other and very near conductors of being separated by, and electric capacity is equivalent to open circuit in DC circuit, and in alternating current circuit, circuit passes through between electric capacity by the form of field.Because electric capacity is widely used in the circuit, and the change in voltage amplitude in some circuit is bigger, cause electric capacity breakdown easily, particularly introduce in the circuit of grid alternating current at some, because appearring in alternating current in the electrical network sometimes, surge voltage produces too high voltage, cause the electric capacity in the place in circuit easily breakdown, cause potential safety hazard, electric capacity of the prior art does not also have corresponding safeguard procedures for surge voltage.
Summary of the invention
But the ground capacity that the purpose of this invention is to provide a kind of built-in divider resistance inserts the electric capacity in the electrical network because surge voltage is easily breakdown to solve in the prior art, and electric capacity easily breakdown problem in the bigger circuit of some change in voltage amplitudes.
In order to achieve the above object, the technical solution used in the present invention is:
But a kind of ground capacity of built-in divider resistance, include uncovered housing, described housing open-mouth is covered with end cap, two terminals are installed on the described end cap, the electric capacity core body is arranged in the described housing, described electric capacity core body is electrically connected with two terminals on the end cap by lead, it is characterized in that: lead to earth lead on the lead between described electric capacity core body and the terminal, have access to the push-button switch that is installed on the housing shell wall on the described earth lead, described earth lead passes ground connection behind the housing, has access to resistance on the lead between described electric capacity core body and another terminal.
The present invention is simple in structure, be easy to realize that by drawing earth lead on the lead between electric capacity core body and the terminal, earth lead passes ground connection behind the housing, also can housing be provided with the electric device of analogue ground, earth lead directly is connected on the electric device of analogue ground.Earth lead is provided with push-button switch, need only press the button switch when needing ground connection like this and get final product, and is time saving and energy saving.Carry out dividing potential drop by on the lead between electric capacity core body and another terminal, having access to resistance, can prevent the voltage breakdown electric capacity that amplitude of variation is bigger effectively.The present invention has improved the useful life of electric capacity greatly, has reduced the possibility that potential safety hazard occurs.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1.But a kind of ground capacity of built-in divider resistance, include uncovered housing 1, housing 1 open-mouth is covered with end cap 2, two terminals 3 are installed on the end cap 2, electric capacity core body 4 is arranged in the housing 1, electric capacity core body 4 is electrically connected with two terminals 3 on the end cap 2 by lead 5, lead to earth lead 6 on the lead between electric capacity core body 4 and the terminal, have access to the push-button switch 7 that is installed on housing 1 shell wall on the earth lead 6, earth lead 6 passes housing 1 back ground connection, has access to resistance 8 on the lead between electric capacity core body 4 and another terminal.
