Abstract
The utility model relates to the high-voltage lightning arrester field, and discloses a lightning arrester for a DC thawing apparatus, which comprises a plurality of lightning arrester units, an upper current-sharing plate in parallel connection with the high-voltage end of the lightning arrester units and a lower current-sharing plate in parallel connection with the low-voltage end of the lightning arrester units, wherein an insulated pillar is connected at the bottom of the lightning arrester units.
Description
Technical field
The utility model relates to the high-voltage arrester field, particularly a kind of DC de-icing device lightning arrester.
Background technology
In DC de-icing device, lightning arrester is as important overvoltage protection, and is in parallel with the electric equipment of being protected, and is used to prevent that institute's protection electric equipment from suffering thunder and lightning to involve the operation wave impact.
Because the particularity of the operating condition of DC de-icing device, the connected mode of lightning arrester changes, and its low-pressure end is ground connection no longer, and the discharge capacity that the while DC de-icing device needs is big; And the voltage on the DC de-icing device contains multiple harmonic, to the dirty demands for higher performance of the resistant of lightning arrester.Therefore, common lightning arrester can't satisfy the instructions for use of DC de-icing device.
Summary of the invention
The purpose of this utility model is to provide a kind of DC de-icing device lightning arrester, can cooperate deicing device to use, and discharge capacity is big, all properties of flow is good, anti-pollution characteristic is good.
In order to achieve the above object, the utility model gives by the following technical solutions and realizing.
A kind of DC de-icing device lightning arrester, comprise a plurality of lightning arresters unit, it is characterized in that, also comprise the last homogenizing plate of a plurality of lightning arresters in parallel unit high-pressure side, the following homogenizing plate of a plurality of lightning arresters in parallel unit low-pressure end, described lightning arrester unit bottom is connected with insulation column.
Further characteristics of the present utility model are:
Described insulation column adopts fertile blue epoxy glass fabric tube and silicon rubber full skirt to make.
The bottom of described insulation column is provided with fertile blue epoxy glass fabric tube leg.
Described lightning arrester unit, include insulating cylinder, vertically stacked in insulating cylinder resistor disc and be arranged on full skirt outside the insulating cylinder; Described insulating cylinder adopts epoxy fibreglass to make; Described full skirt adopts silastic material to make.
The utility model adopts a plurality of lightning arresters unit, by upper and lower homogenizing plate and be unified into an integral body, can satisfy the requirement of DC de-icing device to discharge capacity; And, be provided with exhausted edge tube, the insulating cylinder of employing epoxy fibreglass in the lightning arrester bottom and be outside equipped with the silicon rubber full skirt, can play insulating effect first, second improved the dirty performance of resistant.Simultaneously,, adopt the external parallel connection because each lightning arrester unit is relatively independent, its electric strength height, partial discharge quantity is little, and leakage current is little, and ion migration amount is little, has guaranteed the stability and the fail safe of lightning arrester long-time running.
