Description
Technical field
The utility model relates to technical field of electricity, particularly a kind of multi-joint testing terminal adapter.
Background technology
In electric panel cabinet, the testing terminal of three-phase four-wire system electric current, voltage circuit is all Group Design usually, is all one one access during the access of plug-in test wire, easily occurs the phenomenon of phase sequence access mistake.Once phase sequence access mistake, may experimental mistake be caused, even cause equipment damage.In addition; the situation that relay protection current return often has multiple protective device, safety and stability control device and fault wave recording device to be connected in series; stop transport when set of device and overhaul; other devices still charging operation time; test wire is needed to stride across idle (off-stream) unit by the input side of its current return and outgoing side terminal short circuit (abbreviation cross-over connection); conventional test line also can only the short circuit of phase one phase, will affect plant running, and even cause error action of device.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of multi-joint testing terminal adapter, with test wire with the use of, simultaneously short circuit and the cross-over connection of multiple loop can be realized.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of multi-joint testing terminal adapter, comprises insulation tube base, and multiple metallic plug is fixed in insulation tube base side by side, multiple metallic plug, through insulation tube base, is provided with instrument connection at the afterbody of multiple metallic plug.
Preferably, be threaded connection between described multiple metallic plug and insulation tube base, when preventing adapter from plugging, metallic plug departs from insulation tube base.
Preferably, the front end of described multiple metallic plug is provided with spring, and when metallic plug inserts testing terminal instrument connection, spring plays fastening effect.
Preferably, place corresponding from multiple metallic plug in described insulation tube base is marked with different English alphabets, and convenient working personnel distinguish metallic plug and access loop thereof.
Preferably, described metallic plug adopts H62 copper material to make, and is coated with nickel film, plays a protective role to metallic plug on the surface of metallic plug
Preferably, described spring adopts H62 copper material to make, and is coated with nickel film, plays a protective role to spring on the surface of spring.
Said structure the utility model is adopted to have the following advantages:
1, multi-joint testing terminal adapter can form multi-joint short-circuit plug with short circuit test wire, realizes multiple loop simultaneously short circuit, as while short circuit CT secondary current backflow, increase work efficiency;
2, multi-joint testing terminal adapter can form multi-joint shorting stub with short circuit test wire; realize the cross-over connection simultaneously of multiple loop; as striden across certain covering device of interruption maintenance in CT current return; by the cross-over connection simultaneously of the ABCN4 bar loop of its both sides; the protective relaying device malfunction that phase-splitting short circuit causes can be avoided, also reduce the risk of mis-wired to a certain extent.

Embodiment
As shown in Figures 1 to 3, a kind of multi-joint testing terminal adapter, comprises insulation tube base 1, and multiple metallic plug 2 is fixed in insulation tube base 1 side by side, and multiple metallic plug 2, through insulation tube base 1, is provided with instrument connection 4 at the afterbody of multiple metallic plug 2.
Preferably, be connected between described multiple metallic plug 2 with insulation tube base 1 by screw thread 5, when preventing adapter from plugging, metallic plug 2 departs from insulation tube base 1.
Preferably, the front end of described multiple metallic plug 2 is provided with spring 3, and when metallic plug 2 inserts testing terminal instrument connection, spring 3 plays fastening effect.
Preferably, place corresponding from multiple metallic plug 2 in described insulation tube base 1 is marked with different English alphabets, and convenient working personnel distinguish metallic plug 2 and access loop thereof.
Preferably, described metallic plug 2 adopts H62 copper material to make, and is coated with nickel film on the surface of metallic plug 2, plays a protective role to metallic plug 2
Preferably, described spring 3 adopts H62 copper material to make, and is coated with nickel film on the surface of spring 3, plays a protective role to spring 3.
During use, as shown in Figure 4, multi-joint testing terminal adapter can form multi-joint short-circuit plug with short circuit test wire 6, for while short circuit multiple terminal.The metallic plug 2 of multi-joint testing terminal adapter can first pass through short circuit test wire 6 by its afterbody short circuit, more multi-joint testing terminal adapter is inserted the testing terminal needing short circuit, gets final product the multiple terminal of short circuit simultaneously.
As shown in Figure 5, multi-joint testing terminal adapter can form multi-joint shorting stub with short circuit test wire 6, for while cross-over connection multiple terminal.Two groups of multi-joint testing terminal adapters many test wires are joined end to end, forms multi-joint shorting stub.As certain cover protective relaying device interruption maintenance; but be also serially connected with fault wave recording device, stable control device etc. in its CT current return; now can form multi-joint shorting stub by the shown mode of Fig. 5; by the cross-over connection simultaneously respectively of protective relaying device current return input side A, B, C, N terminal and outgoing side A, B, C, N terminal, normal fault wave recording device, the stable control device run is avoided to be affected.
