Abstract
The utility model discloses a lightning arrester of a high voltage electrical device, comprising a lightning arrester, a grounding pole and a discharge counter, wherein the two terminals of the discharge counter are respectively connected with the lightning arrester and the grounding pole via shielding cables, one side of the bottom of the lightning arrester is equipped with a flow passage device,the wire inlet end of the flow passage device is connected with the low voltage output end of the lightning arrester, and the wire inlet end of the flow passage device is connected with the grounding pole via a shielding cable. The lightning arrester can be equipped with the discharge counter in a place far from the lightning arrester so as to convenient for people to observe, without changing the structure of a current lightning arrester or reducing the protection level of the lightning arrester, besides, the installation and maintenance are convenient, and the shield cables are saved.
Description
Technical field
The utility model belongs to electrical equipment technical field, particularly a kind of high voltage electric equipment lightning arrester.
Background technology
Traditional arrester discharge counter is normally connected by insulated conductor and is installed in institute's survey lightning arrester nearby, and lightning arrester is generally all rack-mount, and is far away apart from ground.Particularly the high-tension line lightning arrester is overhead then farther, need climb eminence during observation, very inconvenience, and be prone to cause personal injury accidents, therefore often can not observe in time, influence the actual monitoring effect.If increase insulated conductor length, discharge counter is directly drawn to get off, then resistance is excessive between lightning arrester and discharge counter, is prone to cause residual voltage of arrester to raise, and makes the lightning arrester overvoltage protection level descend.Up to now, this problem fails to obtain comparatively desirable solution always.
The utility model content
The purpose of the utility model is to provide a kind of and can be implemented under the prerequisite that does not reduce the protection of arrester level; Discharge counter moved to be installed in be convenient to the place that people observe away from lightning arrester; And easy for installation, can practice thrift the high voltage electric equipment lightning arrester of shielded type cable again.
The technical scheme that purpose adopted that realizes the utility model is: this device comprises lightning arrester, ground connection pole and discharge counter; Two terminals of discharge counter are connected with lightning arrester, ground connection pole respectively through shielded type cable; One side is equipped with through-flow device in the bottom of lightning arrester; The end of incoming cables of this through-flow device is connected with the low-voltage output of lightning arrester, and leading-out terminal is connected with ground connection pole through shielded type cable.
Connect the high voltage electric equipment lightning arrester of processing according to such scheme; Need not change the structure of existing lightning arrester; Can be implemented under the prerequisite that does not reduce the protection of arrester level; Discharge counter is installed in the place of being convenient to people's observation away from lightning arrester, and installation and maintenance are convenient, practice thrift shielded type cable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The high voltage electric equipment lightning arrester of the utility model; This device comprises lightning arrester 1, ground connection pole 3 and discharge counter 4; Two terminals of discharge counter 4 are connected with lightning arrester 1, ground connection pole 2 respectively through shielded type cable; A side is equipped with through-flow device 2 in the bottom of lightning arrester 1, and the end of incoming cables of this is through-flow device 2 is connected with the low-voltage output of lightning arrester 1, and leading-out terminal is connected with ground connection pole 3 through shielded type cable.Said through-flow device 2 can directly be purchased on market; This device through through-flow device 2 setting and with discharge counter 4 parallelly connected formation ground connection double loop structures; By the loop of through-flow device 2 current impedance that the jump lead of discharge counter 4 produces is compensated; Not only can move the installation site of discharge counter 4 arbitrarily, make things convenient for the staff to observe, can make lightning arrester 1 obtain reliable protection simultaneously.Simultaneously,, need not change the original structure of existing lightning arrester, and installing and replacing is very convenient, therefore is specially adapted to the transformation of existing lightning arrester because this device is on existing lightning arrester, directly to set up through-flow device 2.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection range of the utility model.
