Description

For testing the portable dam of remote signalling transmission test
Technical field
The utility model relates to a kind of for testing the portable dam of remote signalling transmission test, is applicable to the remote signals transmission test of measure and control device in electric system.
Background technology
Often can relate to the remote signals transmission test of measure and control device in the daily production of electric system, transformation, examination and defect elimination work.Can relate to charged short circuit, charged work of taking out stitches in transmission test work.Current phase signal transmission work is carried out by hand by the crewmember fully, and the instrument of use is that a wire and is screwdriver.Signal of normal condition underdrive, need to use wire that common port positive electricity on terminal row is shorted to signal end; While meeting special circumstances (close node as usual or relay adhesive), need signal end external loop on terminal row is removed with slot signal.In carrying out the course of work, often there will be the signal that need to take out stitches and need short circuit mutually to intert, make staff's work efficiency low.And the electric pressure of all signal circuits is 220V direct current forceful electric power, so just cause having the danger of DC earthing when using the wire short circuit or removing external loop, and the staff there is the danger of electric shock.
The utility model content
Technical problem to be solved in the utility model has been to provide a kind of for testing the portable dam of remote signalling transmission test.
The utility model solves the technical scheme that its technical matters adopts:
The utility model comprises screw, insulating sleeve with insulated handle, be positioned at a word screwdriver of insulating sleeve, connect the wire of a word screwdriver and screw;
A described word screwdriver is comprised of insulation handle and metal conehead; Described insulating sleeve upper and lower opening, the insulating sleeve upper shed is stretched out on the top of the insulation handle of a described word screwdriver, and the metal conehead of a described word screwdriver is over against the insulating sleeve under shed; Be provided with the first spacing ring in described insulating sleeve upper inner, its internal diameter is greater than the diameter of the insulation handle of a described word screwdriver; The insulation handle outside at a described word screwdriver is provided with the second spacing ring, and its external diameter is greater than the internal diameter of described the first spacing ring; Described the second spacing ring is positioned at the bottom of described the first spacing ring; Described spring housing is on the metal conehead of a described word screwdriver; One end of described wire and the nut of screw are connected, and the other end is connected with the metal conehead of a described word screwdriver by the hole be positioned on the insulating sleeve sidewall.
The good effect that the utility model produces is as follows: the utility model unites two into one the function of wire and screwdriver in remote signalling restricting the number transmission test, cost of development is low, staff's left-hand seat is simple, at needs, take out stitches and short circuit has improved work efficiency in interspersed test procedure mutually effectively, in the signal circuit that is 220V direct current forceful electric power in electric pressure, adopt the connection sheet screw of insulator cap and a word screwdriver that can stretch in insulating sleeve, reduce potential safety hazard, be conducive to the power system safety and stability operation.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1 insulated handle, 2 screws, 3 wires, 4 insulating sleeves, 5 first spacing rings, 6 one word screwdrivers, 7 second spacing rings, 8 springs, 9 holes.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment as shown in Figure 1 is known, and it comprises screw 2, insulating sleeve 4 with insulated handle 1, be positioned at a word screwdriver 6 of insulating sleeve 4, connect the wire 3 of a word screwdriver 6 and screw 2;
A described word screwdriver 6 is comprised of insulation handle and metal conehead; Described insulating sleeve 4 upper and lower openings, insulating sleeve 4 upper sheds are stretched out on the top of the insulation handle of a described word screwdriver 6, and the metal conehead of a described word screwdriver 6 is over against insulating sleeve 4 under sheds; Be provided with the first spacing ring 5 in described insulating sleeve 4 upper inner, its internal diameter is greater than the diameter of the insulation handle of a described word screwdriver 6; The insulation handle outside at a described word screwdriver 6 is provided with the second spacing ring 7, and its external diameter is greater than the internal diameter of described the first spacing ring 5; Described the second spacing ring 7 is positioned at the bottom of described the first spacing ring 5; Described spring 8 is enclosed within on the metal conehead of a described word screwdriver 6; One end of described wire 3 is connected with the nut of screw 2, and the other end is connected with the metal conehead of a described word screwdriver 6 by the hole 9 be positioned on insulating sleeve 4 sidewalls.
Be fixed with insulated handle 1 on the nut of described screw 2, adopt and exempt from the manufacture of instrument concept, facilitate the staff install on terminal row or remove with hand; The bottom of described screw 2 has metal threaded, can be screwed in the screw of terminal Volleyball Association sheet.One end of described wire 3 firmly is welded on screw 2, and its other end is soldered on the metal conehead of a word screwdriver 6, forms conductive path.In order to ensure the security of staff and straight-flow system, installed insulating sleeve 4 additional in word screwdriver 6 outsides, and a word screwdriver 6 is with retractable.
The course of work of the present utility model is as follows:
When needs are used a word screwdriver to carry out short circuit work, screw 2 is screwed in the common port positive electricity screw of terminal Volleyball Association sheet, insulated handle by next word screwdriver 6, compress the spring 8 in described insulating sleeve 4, one word screwdriver 6 stretches out 2cm from insulating sleeve 4, the metal conehead of a mobile word screwdriver 6 is connected to the unlike signal end of required measurement, facilitates the staff to work and avoids contact danger simultaneously; When not needing to use, unclamp the insulated handle of a word screwdriver 6, described spring 8 is by the second spacing ring 7 top to the first spacing ring 5 places, and now a word screwdriver 6 is retracted in insulating sleeve 4 fully, the staff can place arbitrarily, can not cause staff's error shock or DC system grounding.When using a word screwdriver to carry out signal end external loop dismounting work, also can use the word screwdriver 6 in the utility model, need not carry again other instruments.
