In the concrete course of work, because the subjectivity of workmen is neglected, usually forget and electrical verification is carried out to circuit.In addition, due to the various power circuit complexes of working site, wrong circuit is hung in easy appearance, or because of reasons such as line influence electricity give, all may there is the phenomenon of power construction personnel live connection of ground wire, thus initiation line-to-ground fault, or directly jeopardize life safety, cause power construction personnel to get an electric shock injures and deaths.
Utility model content
The utility model is the generation for avoiding this type of accident, for the weak point of above-mentioned existing safety measure, a kind of earth connection with electroscope function is provided, verifies whether circuit is charged while hanging earth connection workmen, thus avoid the phenomenon of live connection of ground wire to occur.
The utility model be technical solution problem by the following technical solutions.
Have the earth connection of electroscope function, its design feature is, comprises earthing clamp, earth rod, ground connection copper cash, electrical verification contact and 10kV high-tension acoustooptic electroscope; Described earthing clamp is fixed on one end of described earth rod, and described earthing clamp comprises U-shaped clip slot, arranges two spring leafs for clamping wires in described U-shaped clip slot; On one end of the connection of described U-shaped clip slot and described earth rod, described earthing clamp is fixedly connected with described ground connection copper cash by screw; At the notch place of described U-shaped clip slot, be fixedly installed described electrical verification contact, described earth rod is fixedly installed described 10kV high-tension acoustooptic electroscope, be connected by wire between described electrical verification contact with described 10kV high-tension acoustooptic electroscope.
Described electrical verification contact adopts Reed type structure.
Compared with existing earth connection technology, the utility model beneficial effect is embodied in:
The utility model has the earth connection of electroscope function, at traditional earth connection apical position, electroscope contact is installed, and the high voltage electroscope being positioned at earth connection pole body is connected to by metal, high voltage electroscope is connected with the audible-visual annunciator being positioned at earth connection pole body end.There is the earth connection of electroscope function; except the ground protection function with general earth connection; in use; by being installed at electrical verification contact elder generation on earth connection and conductive contact; if circuit is charged; just can be detected by the 10kV high-tension acoustooptic electroscope being positioned at earth rod, and it is charged to be prompted to power construction personnel circuit by the alarm signal such as sound, light.Thus effectively avoid the accident of live hanging earth connection to occur, the personal safety of protection power construction personnel.If circuit is not charged, then electroscopic device does not do corresponding prompting, does not affect the normal use of earth connection.The earth connection with electroscope function of the present utility model, except the ground protection function with general earth connection, in use, can test to whether power circuit is charged.Effectively can avoid the behavior of electrical employee live connection of ground wire, the probability that reduction accident occurs.
The utility model has the earth connection of electroscope function, has and can carry out electrical verification to being grounded circuit and carrying out sound and light alarm when being grounded circuit and being charged, avoid the phenomenon of live connection of ground wire to occur, protect the advantages such as the personal safety of power construction personnel while connection earth connection.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model has the earth connection of electroscope function.
Label in accompanying drawing 1: 1 earthing clamp, 2 electrical verification contacts, 3 acoustooptical electroscopes, 4 earth rods, 5 ground connection copper cash, 6U clevis groove, 7 screws, 8 spring leafs, 9 wires.
Below by way of embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment
See Fig. 1, the earth connection with electroscope function of the present utility model, comprises earthing clamp 1, earth rod 4, ground connection copper cash 5, electrical verification contact 2 and 10kV high-tension acoustooptic electroscope 3; Described earthing clamp 1 is fixed on one end of described earth rod 4, and described earthing clamp comprises U-shaped clip slot 6, arranges two spring leafs 8 for clamping wires in described U-shaped clip slot 6; At described U-shaped clip slot 6 with on one end of the connection of described earth rod 4, described earthing clamp is fixedly connected with described ground connection copper cash 5 by screw 7; At the notch place of described U-shaped clip slot 6, be fixedly installed described electrical verification contact 2, described earth rod is fixedly installed described 10kV high-tension acoustooptic electroscope 3, be connected by wire 9 between described electrical verification contact 2 with described 10kV high-tension acoustooptic electroscope 3.
Described electrical verification contact 2 adopts Reed type structure.
The earth connection with electroscope function of the present utility model, uses when line maintenance for power construction personnel.When Electric Power Line Overhaul, circuit should have a power failure, to construct.According to code, the code that power construction personnel follow is: power failure, electrical verification, hanging earthing conductor.But in concrete work, minority workmen can miss electrical verification step.
Rotatable style electrical verification contact 2 is installed in the bayonet socket position of described earthing clamp 1, and is connected with the 10kV high-tension acoustooptic electroscope 3 being positioned at earth connection pole body by plain conductor.When staff earthing clamp is stuck in be grounded on circuit time, being grounded circuit first to contact with described electrical verification contact 2 before snapping in U-shaped clip slot, now can carrying out electrical verification by the 10kV high-tension acoustooptic electroscope 3 be electrically connected with described electrical verification contact 2 to being grounded circuit.If it is charged to be grounded circuit, 10kV high-tension acoustooptic electroscope 3 is grounded the charged sound and light alarm signal of circuit by sending, and the staff that can withdraw deposit thus notes, to avoid live line working, thus the personal safety of protection staff.
Described electrical verification contact is the Reed type structure of one end fulcrum type, be arranged on the bayonet socket place of earth connection, the sheet metal of contact can rotate around fulcrum, conveniently assemble and disassemble earth connection, and electrical verification contact is connected to the 10kV high-tension acoustooptic electroscope being positioned at earth connection pole body by plain conductor.Described plain conductor is as within described earth rod.Described earth rod is insulating rod.
Use the earth connection with electroscope function of the present utility model, while user of service hangs earth connection, complete an electrical verification process.By being installed at electrical verification contact elder generation on earth connection and conductive contact, if circuit is charged, just can be detected by the high voltage electroscope being positioned at earth connection pole body, and alarm signal is prompted to power construction personnel by audible and visual alarm.Thus effectively avoid the accident of live hanging earth connection to occur, the personal safety of protection power construction personnel.If circuit is not charged, then electroscopic device does not do corresponding prompting, does not affect the normal use of earth connection.
The above example is described, to allow to be easy to understand the utility model, but above-mentioned example does not limit the utility model.On the contrary, the utility model intends to comprise various remodeling and equivalent, and its scope will be given the widest explanation to comprise all such remodeling and equivalent mechanism under law allows.
