Description
Technical field
The utility model relates to power information lightning protection field, is specifically related to a kind of lightning arrester.
Background technology
It is mostly install lightning arrester additional in batch meter that at present conventional low pressure power information gathers lightning protection, and in batch meter, lightning arrester must carry out ground connection and just can play lightning protection function.Shortcoming is that ground lead is easily destroyed thus do not reach lightning-arrest effect, and each batch meter needs to carry out ground connection, and the expense of generation and workload are very large.
Summary of the invention
In order to solve the problem, the utility model provides a kind of lightning arrester, it is characterized in that, comprise lightning arrester and line protector, described lightning arrester has multiple, multiple lightning arrester is all located on 0.4kV distribution line, and is connected with the live wire on 0.4kV distribution line, zero line, ground wire and center line respectively;
Described line protector is located in batch meter, is connected with 485 order wires in described batch meter;
Described 0.4kV distribution line is connected with the ammeter in described batch meter.
Further, described line protector is protective tube or circuit breaker.
Further, described lightning arrester is located at the head end of described 0.4kV distribution line, end and centre position.
A kind of lightning arrester that the utility model provides, has easy to operate, easy care, low cost and other advantages, effectively serves the effect of concentrator and circuit board in protection batch meter, ensure that the safe and stable operation of power information acquisition system.
Accompanying drawing explanation
Fig. 1 is the structural representation of 0.4kV distribution line zinc oxide surge arresters in a kind of lightning arrester of the utility model;
Fig. 2 collects the structural representation that measuring tank installs line protector in a kind of lightning arrester of the utility model.
Embodiment
The exemplary embodiments embodying the utility model feature & benefits will describe in detail in the following description.Be understood that the utility model can have various changes in different embodiments, it neither departs from scope of the present utility model, and explanation wherein and to be shown in be use when explain in essence, and be not used to limit the utility model.
As depicted in figs. 1 and 2, a kind of lightning arrester is provided, comprise lightning arrester 1 and line protector 2, lightning arrester 1 has multiple, multiple lightning arrester 1 is all located on 0.4kV distribution line 3, and be connected with the live wire on 0.4kV distribution line 3, zero line, ground wire and center line respectively, and lightning arrester 1 is located at the head end of 0.4kV distribution line 3, end and centre position; Line protector 2 is located in batch meter 4, is connected with (485) order wire 5 in batch meter 4; 0.4kV distribution line 3 is connected with the ammeter 6 in batch meter 4.
Concrete; in the present embodiment; lightning arrester 1 has 20; 20 lightning arresters 1 are located at the head end of 0.4kV distribution line 3, end and centre position respectively; can also be 12, not limit at this to the concrete quantity of lightning arrester, line protector 2 is protective tube; also can be circuit breaker, be arranged in described batch meter 4.
The technical program be combined with each other by arranging lightning arrester 1 and arrange line protector 2 protection on 0.4kV distribution line 3 in batch meter 4; lightning protection object is reached from face; effectively serve the effect of concentrator, electric energy meter in protection power information acquisition system, and easy to operate, cost is low.Easy care, ensure that the safe and stable operation of power information acquisition system.
Embodiment above describes the utility model, should be appreciated that term used illustrates and exemplary and nonrestrictive term.Specifically can implement in a variety of forms due to the utility model and not depart from spirit or the essence of utility model, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and explain widely in the spirit and scope that should limit in claim of enclosing, therefore fall into whole change in claim or its equivalent scope and remodeling and all should be claim of enclosing and contained.
