Description
Technical field
The invention belongs to field of electrical equipment, it is related to a kind of arrester.
Background technology
Arrester is used to protect electrical equipment against transient overvoltage harm high, and limits time of afterflow, also often limits continuous
Flow a kind of electrical equipment of assignment.This term is included when operation is installed for any outer gap necessary to the electrical equipment normal function,
Regardless of whether whether it is as an overall part.The arrester complex structure for using at present, it is inconvenient using installing.
The content of the invention
It is an object of the invention to provide a kind of arrester, the arrester uses the design of socket joint type, simple structure, manufacture
Simple installation, using effect is good, with high use value.
The object of the present invention is achieved like this：A kind of arrester, including porcelain bushing, inner sleeve, described ceramic jacket
Inner sleeve is installed in pipe inside, and described inner sleeve includes upper sleeve pipe, medial sleeve, setting of casing, described upper sleeve pipe, medial sleeve
Joined end to end successively from top to bottom with setting of casing and connected together, described upper sleeve pipe is provided with upper end cover, described setting of casing
Bottom end cover is provided with, described upper end cover bottom is connected with coil, described coil lower end connection zinc oxide varistor, institute
The lower end connection bottom end cover of the zinc oxide varistor stated.
Described upper sleeve pipe and each medial sleeve is respectively provided with a coil, and each coil is connected in series.
Described medial sleeve is three.
The outer projection of described porcelain bushing is in umbrella-shaped structure.
Described zinc oxide varistor is arranged in setting of casing.
The beneficial effect comprise that：One is, the present invention is joined end to end set using upper sleeve pipe, middle sleeve and setting of casing
The mode for connecing, simple structure is manufactured easy for installation.Two are, the present invention is mounted with multiple coils being connected in series, and improves safety
Coefficient, makes arrester of the invention more safe and reliable.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure：1st, porcelain bushing 2, inner sleeve 3, upper sleeve pipe 4, medial sleeve 5, setting of casing 6, upper end cover
7th, bottom end cover 8, coil 9, zinc oxide varistor 10, umbrella-shaped structure.
Specific embodiment
Below in conjunction with the accompanying drawings to embodiments of the invention further instruction.
Embodiment 1
As shown in Figure 1, a kind of arrester, including porcelain bushing 1, inner sleeve 2, the described inside of porcelain bushing 1 are installed by inner sleeve
Pipe 2, described inner sleeve 2 includes upper sleeve pipe 3, medial sleeve 4, setting of casing 5, described upper sleeve pipe 3, medial sleeve 4 and traps
Pipe 5 joins end to end connect together from top to bottom successively, and described upper sleeve pipe 3 is provided with upper end cover 6, and described setting of casing 5 sets
Bottom end cover 7 is equipped with, the described bottom of upper end cover 6 is connected with coil 8, the described lower end of coil 8 connection zinc oxide varistor
9, the lower end of described zinc oxide varistor 9 connects bottom end cover 7.
Described upper sleeve pipe 3 and each medial sleeve 4 is respectively provided with a coil 8, and each coil 8 is connected in series.
Described medial sleeve 4 is three.
The outer projection of described porcelain bushing 1 is in umbrella-shaped structure 10.
Described zinc oxide varistor 9 is arranged in setting of casing 7.
The present invention is when in use：A kind of arrester, including porcelain bushing, inner sleeve, the inside of ceramic jacket official are installed by inner sleeve
Pipe, inner sleeve is divided into sleeve pipe, three medial sleeves and setting of casing, and upper sleeve pipe, three medial sleeves and setting of casing are from top to bottom
Join end to end successively and connect together, a coil is respectively provided with upper sleeve pipe and each medial sleeve, and each coil is connected
Connection, the bottom connection zinc oxide varistor of coil；In addition, in order to increase creep distance, outside in porcelain bushing sets one
The umbrella-shaped structure at fixed interval.When there is transient voltage high to pass through this arrester, transient voltage high is by the coil connected and oxidation
The collective effect of zinc piezoresistive wafer, transient voltage high is imported into the earth.
Generally, the present invention have the advantages that simple structure, it is reasonable in design, be easily installed and repair, using effect it is good.
