Technical field
The utility model relates to fault line selection device technical fields, relate in particular to a kind of hand-held failure line selection dress
It sets.
Background technique
As small current neutral grounding system most widely used in electric system, when singlephase earth fault occurs for system,
Because the earth current of fault point is very faint, and the line voltage between three-phase still maintains symmetrically, is in the short time
Any influence will not be generated to power supply, therefore, the mark that we early warning occur in the power system just needs power equipment maintaining people
Member goes to overhaul circuit, is quickly searched by the line selection apparatus of profession in face of the circuit of failure, to avoid band
The huge economic loss come.
When power equipment maintaining personnel are rapidly performed by maintenance to circuit, because the earth current of fault point is unusual
Faint, so we need device close to fault point to acquire faint earth current, to pass through examination device pair
The route of fault point is searched, therefore power equipment maintaining personnel need frequently to bend over by holding examination device in maintenance
It is checked, so that the operating burden of power equipment maintaining personnel is increased, meanwhile, it, may because device is during use
It collides, to damage under examination device and wet environment, the damage to device.
Utility model content
In view of the above problem of the existing technology, the one side of the utility model is designed to provide a kind of hand-held event
Hinder line selection apparatus.
To achieve the goals above, a kind of hand-held fault line selection device provided by the utility model, including supporting plate, supporting plate
The outer wall of side is fixedly installed with the steering link block that side is fixedly connected telescopic rod, and the outer wall of telescopic rod is provided with and is used for
The flexible adjusting round bar used is adjusted, the float plate of spring connection is provided at the top of supporting plate, and positioned at supporting plate or so two
Be provided with the fixation device of fixed protection shell in the limiting slot that side opens up, at the top of float plate, protection shell by cabinet and
Top cover composition provided with transparent glass, and cabinet and top cover are provided with the internal interlayer for being equipped with drying plate.Pass through float plate
Floating, thus reduce collision unit generation amplitude to, reduce the damage to examination device, while passing through drying plate
Setting, avoid the moist damage to examination device of external environment.
As a further solution of the present invention: fixed device is provided with by adjuster two sides and is fixedly connected clamping plate
Connecting rod composition, and rubber face block is provided on clamping plate.Examination device is flexibly replaced by adjuster.
The surface of telescopic rod is provided with as a further solution of the present invention, opens with what power pack was electrically connected
It closes, the side at the top of supporting plate is provided with the grafting port being electrically connected with switch.Convenient for controlling check device by holding rod
Work.
Compared with prior art, a kind of hand-held fault line selection device provided by the utility model, by the way that spring is arranged
Float plate and drying plate, reduce in actual use, betide the apparatus for examination and repair that the collision of fixed unit occurs
Damage, while also playing the effect of dehumidifying；And device is by the adjusting round bar on telescopic rod, control device it is flexible, thus
Apparatus for examination and repair is reduced when close to fault point, electric power overhaul personnel do not need frequently to repeat to bend over, to cause maintenance people
Member's is tired out.
It should be appreciated that foregoing general description and it is described in detail below be merely exemplary with it is illustrative, rather than use
In the limitation disclosure.
