Abstract
The utility model relates to a secondary terminal short-circuit ground connector. The secondary terminal short-circuit ground connector is characterized by comprising a connected short-circuit insertion spring, a ground connection fish-shaped clamp and insulating sheaths. The connected short-circuit insertion spring is provided with elastic plugs, two ends of the elastic plugs are respectively in series connection with the adjacent elastic plugs, the ground connection fish-shaped clamp is electrically connected with one end of the connected short-circuit insertion spring, and the insulating sheaths are respectively sleeved at the series-connection positions of the elastic plugs of the connected short-circuit insertion spring and a handle of the ground connection fish-shaped clamp. When the secondary terminal short-circuit ground connector is in use, the elastic plugs are directly inserted into secondary terminal plugholes of a capacitance type current transformer, the ground connection fish-shaped clamp is grounded, and insulating tests of the capacitance type current transformer can be performed. After the tests are finished, the ground connection fish-shaped clamp is loosened, and the elastic plugs are pulled out. The secondary terminal short-circuit ground connector has the advantages of being simple in structure, economical, suitable, convenient to carry, safe and efficient and having reliability in short circuit.
Description
Technical field
The Insulation Test that the utility model relates to power industry detects, and is the secondary terminals short circuit grounding device that a kind of 66kV of being applicable to and above capacitive battery current transformer Insulation Test detect.
Background technology
When 66kV and above capacitive battery current transformer Insulation Test, need to carry out short circuit ground connection to secondary terminals, to prevent high voltage, threaten the person and device security.The method of existing short circuit 66kV and above capacitive battery current transformer secondary terminals has two kinds: a kind of is bare copper stranded wire to be fixed on one by one on the secondary terminals of capacitive battery current transformer with screwdriver, carry out the Insulation Test detection, waste time and energy, easily damage trip bolt and line bank and reduce the secondary connection fastening strength.Another is to buy professional second short circuit earth connection, although the short circuit effect is relatively good, capacitive battery current transformer secondary terminals jack size is different, needs the second short circuit earth connection of configuration different size plug, increases cost, carries again inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is: overcome the shortcoming of prior art, provide a kind of simple in structure, short circuit is reliable, economic and practical, easy to carry, secondary terminals short circuit grounding device safely and efficiently.
The scheme of the utility model technical solution problem is: a kind of secondary terminals short circuit grounding device, it is characterized in that: it comprises that the disjunctor short circuit is inserted spring, the ground connection fish is pressed from both sides and insulating sleeve, described disjunctor short circuit is inserted spring and is provided with some side openings, hollow elastic plug, connect and be integrated with adjacent elastic plug respectively in the two ends of elastic plug opening, ground connection fish folder is electrically connected to the end that the disjunctor short circuit is inserted spring, and insulating sleeve is socketed in respectively in series connection place and handle that the ground connection fish is pressed from both sides of elastic plug of the slotting spring of disjunctor short circuit.
The utility model secondary terminals short circuit grounding device, in the capacitive battery current transformer secondary terminals jack that the elastic plug that its disjunctor short circuit is inserted spring utilizes the elasticity of wire rod to make can be inserted into all size, and short circuit is reliable, the disjunctor short circuit that elastic plug series connection is integrated is inserted spring without fixing cord one by one.During use, the elastic plug of the utility model secondary terminals short circuit grounding device is directly inserted in capacitive battery current transformer secondary terminals jack, ground connection fish clamping connection ground, formed the second short circuit ground path, can carry out the Insulation Test of capacitive battery current transformer, test completely, unclamp ground connection fish folder, extract elastic plug.Have simple in structure, short circuit is reliable, economic and practical, easy to carry, advantage safely and efficiently.
The accompanying drawing explanation
The master that Fig. 1 is the utility model secondary terminals short circuit grounding device looks schematic diagram;
The A-A section enlarged diagram that Fig. 2 is Fig. 1.
In figure: 1 disjunctor short circuit is inserted spring, 2 insulating sleeves, 3 handles, 4 ground connection fish folders, 5 series connection place, 6 elastic plugs.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1～Fig. 2, the utility model secondary terminals short circuit grounding device, it comprises that the disjunctor short circuit inserts spring 1, ground connection fish folder 4 and insulating sleeve 2, described disjunctor short circuit is inserted spring 1 and is provided with some side openings, hollow elastic plug 6, connect and be integrated with adjacent elastic plug 6 respectively in the two ends of elastic plug 6 openings, the disjunctor short circuit is inserted the elastic wire that the material of spring 1 is conduction, ground connection fish folder 4 is electrically connected to the end that the disjunctor short circuit is inserted spring 1, and insulating sleeve 2 is socketed in respectively series connection place 5 of elastic plug 6 of the slotting spring 1 of disjunctor short circuit and ground connection fish and presss from both sides on 4 handle 3.
The utility model secondary terminals short circuit grounding device, the elastic plug 6 that its disjunctor short circuit is inserted spring 1 utilizes the elasticity of wire rod to make, can be inserted in the capacitive battery current transformer secondary terminals jack of all size, and short circuit is reliable, the disjunctor short circuit that elastic plug 6 series connection is integrated is inserted spring 1 without fixing cord one by one.During use, the elastic plug 6 of the utility model secondary terminals short circuit grounding device is directly inserted in capacitive battery current transformer secondary terminals jack, the ground connection fish is pressed from both sides 4 ground connection, formed the second short circuit ground path, can carry out the Insulation Test of capacitive battery current transformer, test completely, unclamp ground connection fish folder 4, extract elastic plug 6.
