Description
Technical field
The utility model belongs to the auxiliary device of electrical primary equipment test, is used when transforming plant primary equipment is tested
Test lead box, especially a kind of multifunctional electric test lead automatic line receiver.
Background technology
Project is more in electrical equipment routine test, and some pilot projects are complex, and wire used is more, tests
As long as careless slightly wire can become very in disorder in journey, wire is caused mutually to wind, it is not easy to tidy up.Some pilot projects I
Need measurement in real time to flow through the voltage and current of wire, traditional test lead does not measure the function of electric current and voltage.With
Upper two aspect adds the complexity of electrical equipment routine test, influences operating efficiency.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of multifunctional electric test lead is automatic
Spooler, there is automatic takeup and measurement in real time to flow through the function of wire voltage and electric current.
The utility model solves its technical problem and takes following technical scheme to realize：
A kind of multifunctional electric test lead automatic line receiver, it is characterised in that：Including housing, coiling clockwork spring, voltage electricity
It is a hollow cylinder barrel shaped structure to flow detection unit and clockwork spring fixed knob, housing, in housing inner diameter to being symmetrically hinged with
Two pass housing upper surface and are provided with clockwork spring fixation rotation with the homoaxial coiling clockwork spring of housing, the upper end of coiling clockwork spring
Button, is fixed with a voltage and current detecting unit in the middle part of the bottom plate in housing, voltage and current detecting unit by wire connect around
The three-phase conducting wire wound on line clockwork spring.
Moreover, the cylinder barrel shaped structure that housing is made up of bottom plate, cover plate and annular side plate, the annular side plate of housing
Radial direction both ends are symmetrically formed with wire hole.
Moreover, there is scale on the three-phase conducting wire.
Moreover, it is formed with winding slot on coiling clockwork spring.
Moreover, coiling clockwork spring lower end hinge is mounted on the bottom plate of housing and is provided with return spring.
The advantages of the utility model and good effect are：
1st, using the utility model when wire is pulled outward spiral power spring storaging energy, move to ideal length clockwork spring peg button revolve
LOCK gears are gone to, clockwork spring can be fixed, and be rotated when clockwork spring peg button to UNLOCK gears, clockwork spring revolution, you can leading
Line automatic winding, is recovered in line box.
2nd, voltage and current detecting unit of the present utility model can detect the voltage and current of display three-phase conducting wire in real time, and
The real-time display on liquid crystal display, the voltage and current warning value of voltage and current detecting unit can also be set, when reaching warning value
When, the unit can send alarm.
