Abstract
The utility model belongs to power transmission and distribution equipment, and particularly provides an insulating tool specialized for primary phase checking of a handcart type switchgear. The insulating tool comprises an insulating rod. The top end of the insulating rod is fixedly connected with a screw. The middle part of the screw is provided with a spacing board which is in threaded connection with a screw rod. The spacing board is provided with a projection which is matched with a spacing baffle plate on the switchgear. The top end of the screw rod is provided with a shift fork which is in empty sleeve connection with the screw rod. The shift fork can drive a valve mechanism transmission pin which is arranged on the switchgear. The insulating tool specialized for primary phase checking of the handcart type switchgear has the following functions: realizing simple structure and convenient use, stably supporting the valve of the switchgear, and effectively ensuring a fact that the valve of the switchgear is always in the open state in the primary phase checking process.
Description
Technical field
The utility model belongs to equipment for power transmission and distribution, relates to a kind of instrument in nuclear phase process of central switch cabinet, specifically nuclear phase special isolation instrument of a kind of handcart switch cabinet.
Background technology
Nuclear phase of central switch cabinet is the important step of inspection work before power transmission, consistent to guarantee transmission line phase sequence.In the process of nuclear phase, switch cabinet shutter is the state in opening always.Traditional nuclear phase guarantees that with insulating bar supporting switch cabinet valve baffle plate switch cabinet shutter is in opening, but easily because of weak, causes slip, affects nuclear phase.
So need a kind ofly can to make switch cabinet shutter stable, special isolation instrument in opening reliably always in a nuclear phase process.
Utility model content
Problem to be solved in the utility model be to provide a kind of can stable support switch cabinet shutter and effectively guarantee switch cabinet shutter nuclear phase special isolation instrument of the handcart switch cabinet in opening always in a nuclear phase process.
The technical solution of the utility model is: nuclear phase special isolation instrument of a kind of handcart switch cabinet, comprise insulating bar, the top of described insulating bar is fixedly connected with screw rod, the middle part of described screw rod is provided with the limiting plate coordinating with screw flight, on described limiting plate, be provided with the protuberance matching with postive stop baffle on switch cubicle, the top of described screw rod is provided with the shift fork being connected with screw rod empty set, and described shift fork can drive the valve mechanism gear pin being arranged on switch cubicle.
In technique scheme, be provided with the support bar being fixedly connected on shift fork on described shift fork, described support bar matches with the hole being arranged on limiting plate, and described support bar can relatively move with limiting plate.
In technique scheme, on described shift fork, be provided with the guiding surface being pressed on valve mechanism gear pin.
The utility model has the advantages that: 1. simple in structure, easy to use.2. adopt screw rod limiting fixation principle, by the length that regulates shift fork to stretch out, withstand bearing pin, so opening switch cabinet valve, simple to operation 3. because the nuclear phase space of switch cubicle is smaller, and staff can make work become very inconvenient too much.And use insulating bar supporting switch cabinet valve baffle plate easily to cause two-phase to get an electric shock.After using this instrument, reduced staff quantity, improved operating efficiency, reduced the danger of staff's low-voltage electric shock and equipment line to line fault.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
Embodiment
As shown in the figure: nuclear phase special isolation instrument of a kind of handcart switch cabinet, comprise insulating bar 1, the top of described insulating bar is fixedly connected with screw rod 2, the middle part of described screw rod is provided with the limiting plate 3 with screw rod 2 threaded engagement, on described limiting plate, be provided with the protuberance 3-1 matching with postive stop baffle B on switch cubicle, the top of described screw rod 2 is provided with the shift fork 4 being connected with screw rod 2 empty sets, is provided with the guiding surface 6 that is pressed in valve mechanism gear pin A on described shift fork 4.
On described shift fork 4, be provided with the support bar 5 being fixedly connected on shift fork 4, described support bar matches with the hole being arranged on limiting plate 3, and described support bar 5 can relatively move with limiting plate 3.
During work, the postive stop baffle on switch cubicle matches with the front end face of protuberance 3-1 on limiting plate 3, makes limiting plate 3 limited, can not move forward.Rotate insulating bar 1, shift fork 4 is moved forward with respect to limiting plate 3, finally make shift fork 4 drive and be arranged on the valve mechanism gear pin A on switch cubicle, valve mechanism gear pin A driving switch cabinet valve is opened.Whole insulating bar is stuck between the postive stop baffle on valve mechanism gear pin A and switch cubicle simultaneously, by reliable positioning supports, avoids valve accidental fall.
