Abstract
The utility model relates to a dual-purpose test device of switchgear, which is composed of an insulating lead wire sheath, an insulated tube and a wire. A cuttage grafting joint is formed at an end of the insulating lead wire sheath which is connected with the conical surface of the 250A standard tube, and a bolt which is gear to the pin hole of the 250A standard tube is arranged at the terminal of the insulated tube at the same side. The bolt is connected with the wire which is positioned in the insulated tube. At the other end, a cuttage grafting joint is formed which is connected with the conical surface of the 630A standard tube, and a screw rod which is matched with the screw of the 630A standard tube is arranged at the terminal of the insulated tube at the same side. The screw rod is connected with the wire which is positioned in the insulated tube. Once the structure is adopted, the connection of the two different type tubes of the 250A standard tube and the 630A standard tube can be achieved, and so all types of experiments of inspection, field test and delivery test of the switchgear can be realized. When an end is connected with the bushing, the other end can be connected with the power, the function of various types of electrical tests of the electrical cabinet can be accomplished without the installation of cable and cable accessories.
Description
Technical field:
The utility model relates to the electric cable accessories technical field of using in the power cable engineering, refers in particular to the dual-purpose experimental rig of a kind of switch cubicle.
Background technology:
Now 35kV and following high-tension switch cabinet exist 630A and two kinds of dissimilar insulators of 250A, and this high-voltage electrical cabinet all needs to do dispatch from the factory test and field test, and how to go between becomes a problem to be solved.
Summary of the invention:
The utility model purpose is to overcome the deficiencies in the prior art, provides a kind of switch cubicle rational in infrastructure, safe and reliable, easy and simple to handle, that reliability is high dual-purpose experimental rig.
For reaching above-mentioned purpose, the technical scheme that the utility model provides is: comprise insulator pin sheath, insulated tube, lead, one end of insulator pin sheath forms the connection-peg that matches and be connected with the conical surface of 250A normal sleeve, be provided with the latch that the pin hole of 250A normal sleeve cooperates with the end of the insulated tube of its homonymy, latch is electrically connected with lead in the insulated tube; The other end forms the connection-peg that matches and be connected with the conical surface of 630A sleeve pipe, and the insulated tube end of this side is provided with the screw rod of the threaded engagement of 630A normal sleeve, and the lead in screw rod and the insulated tube is electrically connected.
After adopting said structure, can realize being connected to two kinds of dissimilar sleeve pipes of 250A normal sleeve and 630A normal sleeve with all kinds of tests such as the check that realizes switch cubicle, field test, delivery tests, when an end joint sleeve wherein, can connect power supply at an other end, realize that Electric Appliance Cabinet need not to install the functional effect that cable and electric cable accessories just can be finished various types of electrical tests.
Description of drawings:
Accompanying drawing is the novel structure cutaway view of this use.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further.
See shown in the accompanying drawing 1, the utility model is made of insulator pin sheath 1, insulated tube 2, the lead 3 of silastic material compression moulding, one end of insulator pin sheath 1 forms the connection-peg 11 that matches and be connected with the conical surface of 250A normal sleeve, be provided with the latch 21 that the pin hole of 250A normal sleeve cooperates with the end of the insulated tube of its homonymy, latch 21 is electrically connected with lead 3 in the insulated tube 2; The other end forms the connection-peg 12 that matches and be connected with the conical surface of 630A sleeve pipe, and the insulated tube end of this side is provided with the screw rod 22 of the threaded engagement of 630A normal sleeve, and the lead 3 in screw rod 22 and the insulated tube 2 is electrically connected.
If desired to the switch cubicle insulator test of any one type, only need that this is installed a corresponding end and be connected above the normal sleeve to be tested, latch or screw rod are electrically connected with pin hole or screw thread, reach the safe and reliable of test.The other end can be connected to testing power supply, thereby realizes that a kind of experimental rig can be used for all kinds of tests of two kinds of dissimilar switch cubicle insulators.
The embodiment of the above only is one of case study on implementation of the present utility model; be not to limit practical range of the present utility model with this; so the equivalence that all shapes according to the utility model, structure and principle are done changes, and all should be covered by protection range of the present utility model.
