Abstract
The present invention relates to a kind of lightening arresting method of distribution line near microwave tower, the distance comprising microwave tower and distribution line is greater than 5 times of shaft tower height, installs 5 groups of series gap leakage conductors continuously; The distance of microwave tower and distribution line is less than 5 times of shaft tower height, installs 5 groups continuously and cuts thunder pin.The present invention can make the electric equipment near microwave tower can not occur because microwave tower draws thunder and damage accident; do not affect circuit normal safe to run; facilitate circuit operating analysis, and consider from the factors such as project cost, construction, maintenance and lightning protection effect, reach most economical lightning protection effect.
Description
Technical field
The present invention relates to a kind of lightening arresting method, particularly relate to a kind of lightening arresting method of 10kV distribution line near microwave tower, belong to electric power application.
Background technology
In recent years, communication apparatus was widely used, and in order to strengthen the area coverage of communication signal, microwave tower is built more and more.Because microwave station needs power supply, so generally all build near distribution line.Microwave tower does not generally exceed 50 ~ 80 meters, building not etc.From atmospheric over-voltage angle, it is the same with lightning rod is a kind of thunder carrying-off device, once microwave tower is struck by lightning, can multiple local triggered lightning overvoltage phenomenon simultaneously in larger scope, cause the distribution line near microwave tower and electric equipment to damage because of overvoltage.The lightning protection measures of research distribution line near microwave tower is very important.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, the distance of foundation thunder and lightning area coverage and microwave tower and distribution line, a kind of lightening arresting method of distribution line near microwave tower of appropriate design, be applied to 10kV distribution line near microwave tower, solve the problem that near microwave tower, 10kV distribution line and electric equipment damage because of lightning overvoltage.
Technical scheme of the present invention comprises the steps:
Step 1, when the distance of microwave tower and distribution line is greater than 5 times of shaft tower height, on the distribution line shaft tower that microwave tower is contiguous, installs 5 groups of series gap leakage conductors continuously;
Step 2, when the distance of microwave tower and distribution line is less than 5 times of shaft tower height, on the distribution line shaft tower that microwave tower is contiguous, installs 5 groups continuously and cuts thunder pin;
Step 3, the distribution transformer on the contiguous distribution line of microwave tower and switch two at high-pressure side and low-pressure side all zinc oxide surge arresters, other electric equipment high-pressure side zinc oxide surge arresters.
Lightning arrester in described step 3 is the dropout type zero-clearance zinc oxide lightning arrester of discharge capacity 10kA.
Counter installed by lightning arrester in described step 3.
Advantageous effect of the present invention is as follows:
1, after adopting above lightning protection measures, can not there is the accident damaged because microwave tower draws thunder in the electric equipment near microwave tower;
2, lightning protection measures does not affect the operation of circuit normal safe.
3, counter is installed and facilitates circuit operating analysis.
4, the factors such as project cost, construction, maintenance and lightning protection effect are considered, reach most economical lightning protection effect.
Accompanying drawing explanation
Fig. 1 is the application schematic diagram installing 5 groups of series gap leakage conductors on shaft tower continuously.
Fig. 2 installs the application schematic diagram that 5 groups are cut thunder pin continuously on shaft tower.
In figure, 1, microwave tower, 2, distribution line, 3, lightning arrester, 4, cut thunder pin, 5, thundercloud.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, microwave tower 1 is greater than 5 times of shaft tower height with the distance of 10kV distribution line 2, when being namely greater than 65m, on the distribution line shaft tower that microwave tower is contiguous, installs 5 groups of series gap leakage conductors 3 continuously.As shown in Figure 2, microwave tower 1 is less than 5 times of shaft tower height with the distance of 10kV distribution line 2, when being namely less than 65m, on the distribution line shaft tower that microwave tower is contiguous, installing 5 groups continuously and cuts thunder pin 4; Distribution transformer on the contiguous 10kV distribution line of microwave tower and switch two all install the dropout type zero-clearance zinc oxide lightning arrester of discharge capacity 10kA in high-pressure side and low-pressure side, and the dropout type zero-clearance zinc oxide lightning arrester of discharge capacity 10kA is installed in other electric equipment high-pressure side; Counter installed by lightning arrester.
