Abstract
The utility model discloses a test seal line, comprising a housing, a bobbin rocking bar, a line clamp and a lead. The bobbin rocking bar is positioned at the center of the external of the housing and is connected with a bobbin in the housing. The lead is coiled on the bobbin in the housing and penetrates the housing to connect with the line clamp. The lead is provided with insulating layers at intervals. The test seal line is simple in structure, low in manufacturing cost and convenient to use. That whether a seal line is electrified or not can be tested conveniently, and thus the personal safety of an operator is effectively protected. The line winding and the line rewinding are simple and labor-saving.
Description
Technical field
The utility model relates to a kind of test envelope line, belongs to electric construction tool technical field.
Background technology
Envelope line is mainly used in the experiment work of electrical equipment, for carrying out the electric equipment test of short circuit connection.
In relay protection work, current return is in very important status.Carrying out that female poor device verification or other stop protection, during the work of nonstop switch, still there is electric current in current return, therefore need to carry out short circuit sealing to current return.Current transformer terminal row is various informative, and be used for the envelope line in sealing current loop, also needs multiple different pattern.
Tradition envelope line is all on-the-spot interim making, envelope line mass does not pass a test and has the risk of current return open circuit, and feature is not obvious, in use procedure, be easily retained in scene, cause some current return to forget Kaifeng, the operation of serious harm equipment, and when envelope tape electricity, in the unwitting situation of testing crew, easily cause the person to get an electric shock.During tradition envelope line retractable cable, need to manually roll or emit, waste time and energy.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of test envelope line, the utility model envelope line, and simple in structure, cost of manufacture is low, easy to use; Whether chargedly can easily detect envelope line, effectively protect operating personnel's personal safety; Retractable cable is simply laborsaving.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of test envelope line, comprises shell, bobbin rocking bar, wire clamp and wire; Bobbin rocking bar is positioned at the center of housing exterior and is connected with the bobbin of enclosure; Wire is wound on the bobbin of enclosure, and passes with wire clamp and be connected from shell, and conductor spacing is provided with insulation course.
Preferred shell lower end is provided with electroscope.
Preferred shell lower end is provided with the alarm being connected with electroscope.
Shell and bobbin rocking bar are made by insulating material.
Wire clamp top is made by metal material, and wire clamp bottom is provided with insulation sleeve.
The beneficial effect that adopts technique scheme to produce is: the utility model envelope line, and simple in structure, cost of manufacture is low, easy to use; Whether chargedly can easily detect envelope line, effectively protect operating personnel's personal safety; Retractable cable is simply laborsaving.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
1 is shell, and 2 is bobbin rocking bar, and 3 is wire clamp, and 4 is wire, and 5 is electroscope, and 6 is alarm, and 7 is insulation sleeve, and 8 is bobbin.
Embodiment
A test envelope line, comprises shell 1, bobbin rocking bar 2, wire clamp 3 and wire 4; Bobbin rocking bar 2 is positioned at the center of shell 1 outside and is connected with the bobbin 8 of enclosure; Wire 4 is wound on the bobbin 8 of enclosure, and passes with wire clamp 3 and be connected from shell, and wire 4 is arranged at intervals with insulation course;
Shell 1 and bobbin rocking bar 2 are made by insulating material;
This envelope line is power equipment safety test envelope line, main application is convenient and swift when the large scale electrical power units such as transformer are tested, charged warning device is installed in bottom, and the sound that can give a warning when energising, prevents from occurring when testing crew is careless and inadvertent the danger of electric shock.Envelope line is used insulation rocker actuator, convenient retracted, can repeated multiple timesly use the use that can also save material easily and fast simultaneously.
When the utility model is used, when transformer and other power equipments are tested, will seal line and extract out from shell, after the positions such as terminal block are wound around, with wire clamp clamping, short circuit is carried out in the place that then need to carry out short circuit to equipment.The every 80cm of wire is set to bare copper wire, then 80cm is provided with colorful insulation layer, and bare copper wire can effectively contact with power equipment, and colorful insulation line plays eye-catching effect, makes staff can see very easily the envelope line on equipment.
Envelope tape electricity prompting: when pressurizeing to equipment, after electroscope induction, alarm sends " ticking " buzzer, the blinking red lamp on while alarm, testing crew learns that envelope line is charged more intuitively, thereby has guaranteed the safety of testing crew.
Wire insulation partial design can be become to red, meet the physiologic habit of human eye, on equipment, seem fairly obvious, can avoid testing crew to omit envelope line.
The utility model is used in a plurality of testing grounds at present, is subject to testing the extensive favorable comment of teams and groups; The utility model envelope line articulates conveniently, has shortened the repair time, has improved work efficiency; The problem that need to manually roll or emit while having solved traditional envelope line retractable cable.
A test envelope line, comprises shell 1, bobbin rocking bar 2, wire clamp 3 and wire 4; Bobbin rocking bar 2 is positioned at the center of shell 1 outside and is connected with the bobbin 8 of enclosure; Wire 4 is wound on the bobbin 8 of enclosure, and passes with wire clamp 3 and be connected from shell, and wire 4 is arranged at intervals with insulation course;
Shell 1 and bobbin rocking bar 2 are made by insulating material;
