Abstract
The invention discloses a grounding switch which comprises an angle iron seat, a cross rod, a pillar and a wiring terminal. The angle iron seat is arranged at two ends of the cross rod and is fixedly connected to the cross rod. The pillar is installed on the cross rod. One side of the pillar is equipped with a connection rod which is provided with a damping spring. The end of the connection rod is provided with a rotating shaft. The connection rod is hinged to the angle iron seat through the rotating shaft. The wiring terminal is fixed to the pillar whose middle part is equipped with a sleeve tube which is internally provided with a copper stranded wire. The end of the copper stranded wire is equipped with a fixed rod whose bottom is provided with a spiral rib. The spiral rib is welded to the fixed rod. The grounding switch has the advantages of convenient installation, high structural strength, a good conductive effect, and safe and reliable use.
Description
Technical field
The present invention relates 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 time
Electric current (such as short circuit current) under interior carrying non-normal condition, but the electric current under the conditions of not requiring it to carry normal circuit.Make
Become artificial ground, meet protection and require.
Ground connection ground connection refers to lead outside power system and the neutral point of electric device, the exposed conductive part of electrical equipment and device
Electricity part is connected with the earth via conductor.Working earthing, lightning protection and protective grounding can be divided into.Working earthing is exactly by electricity
Force system runs (as the neutral ground) needing and arranging, and therefore just has electric current under normal circumstances and flows through ground connection electricity for a long time
Pole, but simply several amperes to tens amperes of out-of-balance current.When system occurs earth fault, have the work of kiloampere
Flow through ground electrode as electric current, but this electric current can be excised by protective relaying device in 0.05 ~ 0.1s, even standby is protected
Shield, action is typically also within 1s.Lightning protection is the ground connection setting to eliminate overvoltage dangerous influence, such as discharging rod, keep away
Thunder line and the ground connection of spark gap.Lightning protection simply just has electric current in the presence of lightning impulse and flows through, and flows through lightning protection
The amplitude of lightning current of electrode is up to tens of to up to a hundred kiloamperes, but the persistent period is very short.Protective grounding is to prevent equipment
Jeopardize the ground connection set by personal safety because insulation damages are powered, such as the metal shell of power equipment, steel reinforced concrete pole and gold
Belong to shaft tower.Protective grounding simply just has electric current in the case of apparatus insulated damage and flows through, and its value can be interior in a big way
Change.
Inconvenience installed by existing earthed switch at present, and structural strength is relatively low, and conductive effect is general.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of easy for installation, structural strength height, and conductive effect is good, using peace
Reliable earthed switch entirely.
For solving the above problems, the present invention adopts the following technical scheme that a kind of earthed switch, including angle bar seat, cross bar, props up
Post and binding post, described angle bar seat is located at cross bar two ends, and described angle bar seat is fixedly connected with cross bar, and described pillar is arranged on horizontal stroke
On bar, described pillar side is provided with connecting rod, and described connecting rod is provided with damping spring, and described connecting rod end is provided with rotating shaft,
Described connecting rod is hinged with angle bar seat by rotating shaft, and described binding post is fixed on pillar, is provided with sleeve pipe in the middle part of described pillar,
It is provided with copper stranded conductor, described copper stranded conductor end is provided with fix bar, and described bottom of fixed is provided with spiral bar in described sleeve pipe,
Described spiral bar is welded with fix bar.
Preferably, described pillar is provided with three, holding structure is reliable and stable.
Preferably, described copper stranded conductor is electrically connected with binding post, keep connection smooth.
Preferably, described connecting rod is fixedly connected with pillar, holding structure is reliable and stable.
Preferably, described angle bar seat bottom is provided with installing hole, conveniently installed.
The invention has the benefit that the angle bar seat holding structure intensity of setting is high, easily install；Have on the pillar of setting
Binding post, facilitates electric wire to install；The damping spring of setting being capable of lift structure stability；The copper stranded conductor of setting keeps conductive effect
Really good, can bend simultaneously, keep easy for installation；The bottom of fixed of setting has spiral bar, can keep being firmly installed in
Underground.

11, described spiral bar 11 and fix bar 10 are welded.
Described pillar 3 is provided with three.
Described copper stranded conductor 9 and binding post 4 are electrically connected with.
Described connecting rod 5 is fixedly connected with pillar 3.
Described angle bar seat 1 bottom is provided with installing hole 12.
The invention has the benefit that the angle bar seat holding structure intensity of setting is high, easily install；Have on the pillar of setting
Binding post, facilitates electric wire to install；The damping spring of setting being capable of lift structure stability；The copper stranded conductor of setting keeps conductive effect
Really good, can bend simultaneously, keep easy for installation；The bottom of fixed of setting has spiral bar, can keep being firmly installed in
Underground.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any
