Abstract
The invention discloses an on-load tap-changer electric drill bit. The on-load tap-changer electric drill bit comprises a cylindrical rotating head body, the upper end of the rotating head body is provided with a circular hole, the lower end of the rotating head body is provided with a connector which can be fixed to an electric drill, and a clamping tongue is longitudinally arranged in the circular hole. The electric drill bit is suitable for electric drills, the manual hand cranking mode of rotating an on-load tap-changer rotor is changed into the mode of holding the motor with the hand to rotate the on-load tap-changer rotor at a low speed, the labor intensity of workers is reduced, and work efficiency is improved.
Description
Technical field
The invention belongs to power equipment maintaining field of tool, include the rotating connector of on-load shunting switch.
Background technology
Voltage is an important quality index in power system.When power system normally moves, it is abnormal that the variation of voltage will make consumer work occur, directly impact is produced and daily life.Therefore voltage-regulation is one of power system main task.Transformer on-load voltage regulating is to carry out voltage adjustment by load ratio bridging switch in the situation that of not power-off, and load ratio bridging switch is the main device of transformer on-load voltage regulating.
Traditional load ratio bridging switch mechanism case is in the time of inspection operation, if there is catching phenomenon in mechanism case inside, operating personnel need to by load ratio bridging switch from 0 grade hand to 17 grades, then shake back 0 grade from 17 grades, each shelves is 33 circles, amounts to 1122 circles.1122 circles are all no small numerals for anyone, artificial free-hand rotation, effort again consuming time.Meanwhile, the electric operation mode that also must not use shunting switch to carry, in case break gear.
Summary of the invention
Given this, the object of the invention is to provide a kind of light, to rotate quickly load ratio bridging switch electric drill rotary head of being convenient to.
For solving above technical problem, technical scheme provided by the invention is that the rotary head of a kind of load ratio bridging switch electric drill is provided, comprise a cylindric rotary head body, this rotary head body upper end is provided with circular hole, and lower end is provided with the connector that can be fixed on electric drill, in described circular hole, is vertically arranged with block tongue.
Preferably, described rotary head body is carbon fiber rod.
Preferably, described block tongue is tabular, is fixedly installed in circular hole.
Preferably, described block tongue is made up of band steel.
Preferably, described rotary head body Leading end chamfer arranges.
Compared with prior art, a technical scheme tool in technique scheme has the following advantages:
1, electric drill rotary head of the present invention is applicable to electric drill, and the mode of rotating load ratio bridging switch rotor is changed to the hand mode for the drive of handheld electrical machinery low speed of manpower, has reduced staff's labour intensity, has improved operating efficiency.
2, electric drill adapted Rechargeable electric drill of the present invention, changes hand tradition mode for micro-electric rotary pattern, guarantees can not break because rotor speed is too high contact, prevents from starting with to maintain the moment of rotation excessive and break gear simultaneously.

Detailed description of the invention
Describe below in conjunction with accompanying drawing and a specific embodiment.
As shown in Figure 4 and Figure 5, this rotation terminal 6 is outside equipped with and prevents the unexpected containment vessel 5 that rotates terminal 6 that touches the rotation terminal being connected with load ratio bridging switch rotor in prior art, and containment vessel 5 is fixed on load ratio bridging switch mechanism case.Rotate terminal 6 tops and be provided with draw-in groove 7.
The present invention is directed to the structure of prior art transfer moved end and propose new design, referring to Fig. 1 to Fig. 3.The rotary head of the described load ratio bridging switch electric drill of the present embodiment, comprises a cylindric rotary head body 1, and this rotary head body 1 is made up of carbon fiber rod.The upper end of rotary head body is provided with circular hole 2, and lower end is provided with the connector 4 that can be fixed on electric drill.The diameter of circular hole 2 is large than the diameter that rotates terminal 6, and the maximum gauge of rotary head body 1 is little than the internal diameter of containment vessel 5.The interior block tongue 3 that is longitudinally fixedly installed of circular hole 2, as preferably, block tongue 3 is tabular, is made up of band steel.
When use, connector 4 is fixedly mounted on the rotation end of electric drill, and rotary head body 1 inserts containment vessel 5, and circular hole 2 is enclosed within and rotates on terminal 6, and block tongue 3 inserts in draw-in groove 7.Electric drill rotates and drives rotary head body 1 to rotate, and the block tongue 3 of rotary head body 1 drives rotation terminal 6 to rotate.
Electric drill is selected Rechargeable electric drill, belongs to technology maturation product.
Below be only the preferred embodiment of the present invention, it should be pointed out that above-mentioned preferred embodiment should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
