Description
Technical field
The utility model is related to a kind of earthed switch.
Background technology
Earthed switch, for the mechanical switch of circuit ground part, belongs to disconnecting switch classification.It can be in certain hour
Electric current under interior carrying non-normal condition（Such as short circuit current）, but do not require that it carries the electric current under the conditions of normal circuit.Make
Into artificial ground, meet protection and require.
Ground connection refers to power system and the outer conductive part of the neutral point of electric device, the exposed conductive part of electrical equipment and device
Lease making is connected by conductor with the earth.Working earthing, lightning protection and protective grounding can be divided into.Working earthing is exactly by power train
System operation needs and arranges（Such as neutral ground）, therefore just have electric current under normal circumstances and flow through earth electrode for a long time,
But simply several amperes to tens amperes of out-of-balance current.When system occurs earth fault, the work of kiloampere is had
Electric current flows through earth electrode, but the electric current can be cut off by protective relaying device in 0.05 ~ 0.1s, even back-up protection,
Action is typically also within 1s.Lightning protection is the ground connection set to eliminate overvoltage dangerous influence, such as lightning rod, lightning conducter
With the ground connection of arrester.Lightning protection simply just has electric current and flows through in the presence of lightning impulse, flows through lightning protection electrode
Amplitude of lightning current it is very short up to tens of to up to a hundred kiloamperes, but duration.Protective grounding is to prevent equipment because absolutely
Edge is damaged powered and jeopardizes the ground connection set by personal safety, such as the metal shell of power equipment, steel reinforced concrete pole and metallic rod
Tower.Protective grounding simply just has electric current and flows through in the case of apparatus insulated damage, and its value can be in interior variation in a big way.
At present existing earthed switch installs inconvenient, and structural strength is relatively low, and conductive effect is general.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of easy for installation, and structural strength is high, and conductive effect is good, makes
With safe and reliable earthed switch.
To solve the above problems, the utility model is adopted the following technical scheme that：A kind of earthed switch, including angle bar seat, horizontal stroke
Bar, pillar and binding post, the angle bar seat is located at cross bar two ends, and the angle bar seat is fixedly connected with cross bar, the pillar peace
It is mounted on cross bar, the pillar side is provided with connecting rod, damping spring is provided with the connecting rod, the connecting rod end is provided with
Rotating shaft, the connecting rod is hinged by rotating shaft with angle bar seat, and the binding post is fixed on pillar, and the pillar middle part is provided with
Sleeve pipe, is provided with copper stranded conductor in described sleeve pipe, the copper stranded conductor end is provided with fix bar, and the bottom of fixed is provided with spiral shell
Rotation muscle, the spiral bar is welded with fix bar.
Preferably, the pillar is provided with three, holding structure is reliable and stable.
Preferably, the copper stranded conductor is electrically connected with binding post, keep connection smooth.
Preferably, the connecting rod is fixedly connected with pillar, holding structure is reliable and stable.
Preferably, the angle bar seat bottom is provided with installing hole, conveniently installed.
The beneficial effects of the utility model are：The angle bar seat holding structure intensity of setting is high, easily installs；The pillar of setting
On have binding post, facilitate electric wire to install；The damping spring of setting being capable of lift structure stability；The copper stranded conductor of setting keeps leading
Electric effect is good, while can bend, keeps easy for installation；The bottom of fixed of setting has spiral bar, can keep firm peace
It is mounted in underground.

Connecting rod 5 is installed, damping spring 6 is provided with the connecting rod 5, the end of the connecting rod 5 is provided with rotating shaft 7, and the connecting rod 5 passes through
Rotating shaft 7 is hinged with angle bar seat 1, and the binding post 4 is fixed on pillar 3, and the middle part of the pillar 3 is provided with sleeve pipe 8, the set
Copper stranded conductor 9 is provided with pipe 8, the end of the copper stranded conductor 9 is provided with fix bar 10, and the bottom of the fix bar 10 is provided with spiral bar
11, the spiral bar 11 is welded with fix bar 10.
The pillar 3 is provided with three.
The copper stranded conductor 9 is electrically connected with binding post 4.
The connecting rod 5 is fixedly connected with pillar 3.
The bottom of angle bar seat 1 is provided with installing hole 12.
The beneficial effects of the utility model are：The angle bar seat holding structure intensity of setting is high, easily installs；The pillar of setting
On have binding post, facilitate electric wire to install；The damping spring of setting being capable of lift structure stability；The copper stranded conductor of setting keeps leading
Electric effect is good, while can bend, keeps easy for installation；The bottom of fixed of setting has spiral bar, can keep firm peace
It is mounted in underground.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
