Abstract
The utility model discloses a lightning-protection device for a phase isolated bus. The lightning-protection device comprises a phase isolated bus shell and a bus conductor arranged in the phase isolated bus shell; the phase isolated bus shell is provided with a T-shaped shell seat that is communicated with the shell; and the T-shaped shell seat is internally provided with a flow guiding row, a lightning arrester, a bracket, a cover plate and a sealing gasket. One end of the flow guiding row is fixedly connected with one side of the bus conductor the other end of the flow guiding row is connected with one end of the lightning arrester through a flexible connecting line, and the other end of the lightning arrester is fixed on the bracket; the bracket is fixed on the cover plate; the outer edge of the cover plate is connected with a port of the T-shaped shell seat through a plurality of fasteners and the sealing gasket in a sealing way. The lightning-protection device has simple structure, is convenient to install, is reliable in running, can effectively protect the bus and an outlet line of a power generator from being damaged, saves space and is convenient to overhaul.
Description
Technical field
The utility model relates to a kind of phaseisolated bus, and especially a kind of lightning arrester of phaseisolated bus belongs to the transmission equipment accessory technical field.
Background technology
In the outlet phaseisolated bus system of power generator; usually be provided with the combination sideboard of voltage transformer and lightning arrester at the bus mid portion; wherein lightning arrester is mainly used in when preventing that thunder and lightning from attacking; the overvoltage that thunder and lightning causes is damaged bus-bar system and generator outlet circuit, is the effective measures of protection bus and generator outlet circuit.But work as phaseisolated bus more in short-term, generally do not adopt the combinations thereof cabinet, also do not take other safety prevention measures, at this moment taking shelter from the thunder of bus and generator outlet circuit just can not get effective assurance, when thunderbolt, suffer damage easily, had a strong impact on the safe operation of generating set.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy for installation, reliable phaseisolated bus lightning arrester, when phaseisolated bus more in short-term, this device can effectively be protected bus and generator outlet circuit to exempt from thunder and lightning and attack.
The utility model is achieved by the following technical programs:
A kind of phaseisolated bus lightning arrester, comprise the phaseisolated bus shell, be installed in the bus-bars conductor in the phaseisolated bus shell, described phaseisolated bus shell is provided with a T shape outer shell base that connects with housing, be provided with water conservancy diversion row in the described T shape outer shell base, lightning arrester, support, cover plate, sealing gasket, described water conservancy diversion is arranged an end and is fixedlyed connected with described bus-bars conductor one side, the water conservancy diversion row other end is connected with lightning arrester one end by the line that is flexible coupling, the described lightning arrester other end is fixed on the support, described support is fixing on the cover board, and described cover plate outer rim is by a plurality of securing members, sealing gasket is connected with T shape outer shell base port sealing.
The utility model is simple in structure, easy for installation, reliable; When bus and generator outlet circuit have thunder and lightning to attack, the overvoltage that forms between bus-bars conductor and the phaseisolated bus shell is repelled and attacked by water conservancy diversion and is worn lightning arrester, realize discharge, can effectively protect bus-bars conductor and generator outlet circuit not to be damaged, thereby guarantee the safe operation of generating set; The utility model need not to be provided with the combination sideboard of voltage transformer and lightning arrester, saves the space, easy access.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises bus shell 1, is installed in bus-bars conductor 2, T shape outer shell base 3, water conservancy diversion row 4, lightning arrester 5, cover plate 7, sealing gasket 8 in the bus shell 1,
T shape outer shell base 3 is arranged on bus shell 1 outside, is welded on the bus shell 1, with the T shape structure of bus shell 1 formation threeway shape.Also the maintenance window can be set on the T shape outer shell base 3, sealing at ordinary times when needing to change lightning arrester 5, can be opened convenient for maintaining.Water conservancy diversion is arranged 4 one ends and is welded in bus-bars conductor 2 one sides, the other end is connected with lightning arrester 5 one ends by the line 9 that is flexible coupling, lightning arrester 5 other ends by nut be fixed on the support 6 that cover plate 7 middle parts are a shape and fixedly connected, cover plate 7 outer rims are fixedlyed connected with T shape outer shell base port by 16 bolts of a circle.Between T shape outer shell base port and cover plate 7, accompany a sealing gasket 8, prevent that moisture from infiltrating in the bus shell 1.
In addition to the implementation, the utility model can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
