Abstract
The utility model relates to a lightning protection device, particularly a lightning protection device used on a transformer. The lightning protection device comprises a transformer and a lightning arrester, wherein the lightning arrester is fixedly connected with the box body of the transformer through a support, and the ground lead of the lightning arrester is connected to the ground. The lightning protection device has a good lightning arresting effect and is convenient for installation.
Description
Technical field
The utility model relates to a kind of lightning arrester, the lightning arrester that uses on particularly a kind of transformer.
Background technology
The lightning arrester of 10KV transformer; Particularly outdoor traditional installation site all is mounted in the top or the middle part of electric pole basically, and application number is that 02230852.0 utility model discloses a kind of lightning arrester fixed mount, comprises fixed cover and connecting plate that lightning arrester is installed; One end of this connecting plate is last clamp; The other end of this connecting plate is a lower plugboard, installs clamp in the said fixed cover, on transformer is put on the shelf, uses the bolt mounting and fixing support; The other end of this fixed mount is an adapter sleeve, and said lower plugboard is installed in this adapter sleeve.Because it is overhead higher that lightning arrester is installed, when therefore running into big thunder and lightning weather, lightning-arrest effect is undesirable, causes power failure.
Summary of the invention
The purpose of the utility model is intended to overcome the defective of prior art, and a kind of lightning-arrest transformer lightning arrester that does not increase installation cost effective, easy for installation is provided.
The described transformer lightning arrester of the utility model is made up of transformer and lightning arrester, and lightning arrester is fixedly connected with the casing of transformer, and ground lead is connected with ground.
The transformer lightning arrester that these practical new people state, when the line influence thunderstorm hour, lightning arrester is installed on the casing of transformer; Can introduce the earth to lightning voltage as early as possible and normally move, and lightning arrester is installed on the casing of transformer, with respect to traditional installation method with the safety of guaranteeing transformer; Lightning arrester is overhead nearest, and the D.C. resistance of the down conductor of lightning arrester is also minimum, thereby lightning-arrest effect is also best; Experiment through the mine electric substation of several families in Yunnan Province install to confirm that this device can exempt to improve effectively the effect of protection of arrester transformer, makes the transformer relatively more can safe operation; Meanwhile, with respect to traditional device, material that the utility model is total and working hour expense are merely original 1/10; Become present Ground Operation by original work high above the ground, improved the fail safe of operation.The utility model is lightning-arrest effective, easy for installation.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1-transformer, 2-lightning arrester, 3-ground lead, 4-support.
Embodiment
Below in conjunction with accompanying drawing further explanation is newly done in this practicality, but be not limited to embodiment.
Embodiment 1
As shown in Figure 1, the described transformer lightning arrester of the utility model is made up of transformer 1 and lightning arrester 2, and lightning arrester 2 is fixedly connected through support 4 with the casing of transformer 1, and ground lead 3 is connected with ground.
