The utility model adopts the above structure high crimping ground wire device, installation alarm device replaces traditional high crimping ground wire device with induction system on the ground of operation body of rod top presss from both sides the link promptly, can solve that operating personnel has a power failure when articulating the ground wire because the circuit with electricity and the potential safety hazard problem of bringing, has reduced the probability of occurence of failure, has guaranteed the good operation of personal safety and equipment.
Description
Technical field
This utility model relates to ultra-high-tension power transmission line maintenance and maintenance technology field, especially relates to a kind of high-voltage earthing line apparatus.
Background technology
In power transmission and transformation line and controller switching equipment interruption maintenance operation, it is stipulated that after equipment has a power failure, after using electroscope to identify equipment no-voltage, hanging earthing conductor can work again, but there are four dangerous spots in code.
First, in the case of electroscope is malfunctioning, there is potential safety hazard in charged mounting, adds electric alarms based on pattern recognition and induction installation can play the effect of second protection.
Second, can there is faradism after having a power failure in actual track, voltage is relatively low, and electroscope cannot be measured, and electric shock casualty accident easily occurs.
3rd, after electrical verification, then during hanging earthing conductor, there is time difference, if the anti-power transmission of circuit in the middle of this operation, there is the potential safety hazard of live connection of ground wire in operator, if circuit steps on bar operation, the interlude of electrical verification hanging ground-wire also can lengthen, and accident probability also can increase.
4th, after mounting first earth lead, if the anti-power transmission of circuit, and operator do not discover, then hang second contact line, circuit phase fault can be caused, cause personal injury and equipment breakdown.
In view of problem above, it is necessary for designing a kind of high-voltage earthing line apparatus with alarm.
Utility model content
The purpose of this utility model is to provide a kind of high-voltage earthing line apparatus, it is possible to solve operator have a power failure hanging earthing conductor time and the security hidden trouble that bring charged due to circuit, decrease the probability that accident occurs, it is ensured that personal safety and the good operation of equipment.
For achieving the above object, this utility model provides a kind of high-voltage earthing line apparatus, including operation the body of rod, press from both sides and earth lead, also include box body, electric alarm device and induction installation it has been equiped with in described box body, described box body and described earth lead are all fixed on described the connection end pressed from both sides by ground wire screw, and described connection bottom portion is connected with the described operation body of rod, presss from both sides describedly and is made up of described connection end and free end.
Preferably, it is provided with cable clamping interface inside described free end.
Preferably, described earth lead is connected on earth brace.
Preferably, described operation body of rod bottom is provided with handle, and the described operation body of rod and described handle are insulant.
Therefore, this utility model uses the high-voltage earthing line apparatus of said structure, it is possible to solve operator have a power failure hanging earthing conductor time and the security hidden trouble that bring charged due to circuit, decrease the probability that accident occurs, it is ensured that personal safety and the good operation of equipment.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of high-voltage earthing line apparatus embodiment.
Detailed description of the invention
Embodiment
Fig. 1 is the structural representation of this utility model a kind of high-voltage earthing line apparatus embodiment.
1: the operation body of rod；2: earth lead；3: box body；4: ground wire screw；5: connect end；
6: free end；7: cable clamping interface；8: handle；9: earth brace.
As shown in the figure, a kind of high-voltage earthing line apparatus that this utility model provides, including the operation body of rod 1, ground folder and earth lead 2, also include box body 3, electric alarm device and induction installation it has been equiped with in box body 3, box body 3 and earth lead 2 are all fixed on described the connection end 5 pressed from both sides by ground wire screw 4, connect and be connected with the operation body of rod 1 bottom end 5, press from both sides describedly and be made up of connection end 5 and free end 6, this utility model is often overlapping high-voltage grounding wire, electric alarm device and induction installation is added on one action bars of low-voltage short-circuiting line, make just can report to the police outside earth lead distance charging equipment minimum safe distance, operation is first linked with this of alarm device, so operator can take measures in time, with protection against electric shock, ensure that the safety of operator.
Cable clamping interface 7 it is provided with inside free end 6.
The operation body of rod 1 bottom is provided with handle 8, and the operation body of rod 1 and handle 8 are insulant, are surrounded by rubber and can play further insulating effect, it is ensured that the safety of operator outside handle.
Earth lead 4 is connected on earth brace 9.
Work process: in power transmission and transformation line and controller switching equipment interruption maintenance operation, after equipment has a power failure, electroscope is used to identify after equipment no-voltage hanging earthing conductor again, first that action bars with alarm is mounted, because after electrical verification again hanging earthing conductor time have time difference, if the anti-power transmission of circuit in the middle of this operation, there is the potential safety hazard of live connection of ground wire in operator, so adding electric alarm device and induction installation on action bars, make earth lead distance charging equipment just can report to the police outside minimum safe distance, operator can be reminded in time, stop operation.
Therefore, this utility model uses the high-voltage earthing line apparatus of said structure, it is possible to solve operator have a power failure hanging earthing conductor time and the security hidden trouble that bring charged due to circuit, decrease the probability that accident occurs, it is ensured that personal safety and the good operation of equipment.
It is last it is noted that above example is only limited in order to the technical solution of the utility model to be described, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that: the technical solution of the utility model still can be modified or equivalent by it, and these amendments or equivalent also can not make amended technical scheme depart from the spirit and scope of technical solutions of the utility model.
