Description
Technical field
The utility model belongs to electrical device technical field, and in particular to a kind of annular high voltage feedthrough capacitor.
Background technique
Capacitor is common device in electronic circuit and high-tension circuit, and high-voltage capacitance and low can be divided by saying from operating voltage value
Voltage capacitance, the generally capacitor work in 1000 volts of aboves call high-voltage capacitance.At least there are two electricity for all capacitors
Pole is then divided into high-voltage end and low-pressure end for high-voltage capacitance.For high-voltage capacitance generally all in one layer of dielectric of outer packaging,
It avoids directly discharging between two electrodes, uses corresponding insulating materials for different voltage class, while external structure is not yet
Together, the purpose is to increase two interelectrode creepage distances, to improve security and stability.
Currently, high-voltage capacitor is usually to be mounted in high-tension line with independent structure type in power supply field.
In practical applications, high-voltage capacitor tends not to be used alone, but other equipment is cooperated to use simultaneously, such as high-voltage switch gear,
The high pressures primary equipment such as high pressure measurement.Therefore this structure of high-voltage capacitance and mounting means can not only give installment work at present
Many troubles are brought, simultaneously because high pressure primary side connecting node is also more, therefore potential faults are also more.In addition, from
This consideration, individual devices are more, and cost is also higher.
Utility model content
The utility model technical issues that need to address are to provide a kind of hollow structure, can directly be sleeved on breaker height
It presses on conducting rod, space-saving annular high voltage feedthrough capacitor.
To solve the above problems, technical solution adopted in the utility model is:
A kind of annular high voltage feedthrough capacitor, capacitor are annular lamellar hollow structure, are successively high-field electrode from the inside to the outside, exhausted
Edge layer, high-pressure polar plate, dielectric materials layer, low pressure pole plate, insulating sealed layer, wherein high-field electrode is circular ring shape, outside high-field electrode
Insulating layer is passed through by good conductor in the middle part of side and connects high-pressure polar plate, low-field electrode, low tension are set in the middle part of insulating sealed layer
Pole passes through insulating sealed layer by good conductor and connects in the middle part of low pressure pole plate lateral surface.
Further, the high-pressure polar plate and low pressure pole plate height are less than dielectric material layer height, and high-pressure polar plate and
There is certain distance at the both ends of low pressure pole plate apart from dielectric materials layer both ends.
Preferably, the dielectric materials layer is that high-performance ceramic powder forces molding.
Preferably, the high-pressure polar plate and low pressure pole plate are annular silver paste coating.
Preferably, the insulating layer and insulation-encapsulated layer material are insulating resin.
The beneficial effects of adopting the technical scheme are that
The utility model capacitor uses annular lamellar hollow structure, and inside is high-field electrode, and when installation can be by capacitor
Entirety covers on the high-voltage conductive rod of breaker, and capacitor center bore size is matched with breaker conducting rod, the electricity of this structure
Hold convenient for installation and maintenance, optimizes device layout on the whole, utmostly reduce equipment overall dimensions, security and stability
It is further enhanced.
