Abstract
The utility model provides a kind of raising HGIS breaker and tests the speed the device of accuracy, belongs to power accessories technical field.A kind of HGIS breaker that improves tests the speed the device of accuracy, including stainless steel plate, through-hole one is opened up on the stainless steel plate, the stainless steel plate is fixed by screws in the cap locations of Crankarm box, the through-hole one is corresponding with the speed measuring position of connecting lever, and the diameter of the through-hole one is adapted with the outer diameter size of velocity sensor.The original fixed longer support arm of velometer is eliminated using the present apparatus, greatly reduce the shake that mechanical oscillation during testing the speed because of breaker switching on and off cause steel plate to generate, to achieve the purpose that velometer stablizes fixation, so that sensor stabilization is tested the speed, improve the accuracy of HGIS measurement data.
Description
Technical field
The utility model belongs to power accessories technical field, and in particular to a kind of raising HGIS breaker tests the speed accurately
The device of property.
Background technique
(as depicted in figs. 1 and 2) is fixed on switchgear by connecting lever when velometer tests the speed at present, due to breaker
Mechanical oscillation are larger during switching on and off tests the speed, and the arm that tests the speed is longer, and the arm shake that causes to test the speed is larger, lead to the sensing that tests the speed
Device measurement data is unstable, test result inaccuracy.
Utility model content
In view of this, the technical problem to be solved by the utility model is to provide a kind of raising HGIS breakers to test the speed accurately
Property device, eliminate the original fixed longer support arm of velometer using the present apparatus, greatly reduce because breaker switching on and off is surveyed
The shake that mechanical oscillation cause steel plate to generate during speed makes sensor stabilization to achieve the purpose that velometer stablizes fixation
It tests the speed, improves the accuracy of HGIS measurement data.
In order to solve the above technical problems, the technical scheme adopted by the utility model is:
A kind of HGIS breaker that improves tests the speed the device of accuracy, including stainless steel plate, opens up on the stainless steel plate logical
Kong Yi, the stainless steel plate are fixed by screws in the cap locations of Crankarm box, the speed measuring position pair of the through-hole one and connecting lever
It answers, the diameter of the through-hole one is adapted with the outer diameter size of velocity sensor.
Preferably, the stainless steel plate with a thickness of 3mm.
Preferably, the shape of the stainless steel plate is identical as the cover board shape of Crankarm box.
Preferably, through-hole two is set on the stainless steel plate.
Preferably, the screw is connect by the through-hole two with the threaded hole of Crankarm box.
Compared with prior art, its advantages are as follows for the utility model:
The utility model based on the deficiencies of the prior art, provides a kind of raising HGIS breaker and tests the speed the dress of accuracy
It sets, to reduce the mechanical oscillation during testing the speed.Applicant utilizes stainless steel plate and screw system according to many years field practice experience
Utility model device is made, so that velometer is fixed on stainless steel well, it is longer to save original fixed velometer
Support arm (as illustrated in fig. 1 and 2)；Stainless steel plate is screwed on the Crankarm box of switchgear, is greatly reduced because of open circuit
The shake that mechanical oscillation cause steel plate to generate during device switching on and off tests the speed makes to achieve the purpose that velometer stablizes fixation
Sensor stabilization tests the speed, and improves the accuracy of HGIS breaker measurement data.

Specific embodiment
The utility model in order to better understand is further fairly set out in the utility model below with reference to embodiment
Hold, but the protection content of the utility model is not limited solely to the following examples.In the following description, a large amount of tools are given
The details of body more thoroughly understands in order to provide to the utility model.However, aobvious and easy to those skilled in the art
See, the utility model may not need one or more of these details and be carried out.
Embodiment 1
Refering to fig. 1-3, a kind of HGIS breaker that improves tests the speed the device of accuracy, including stainless steel plate 1, on stainless steel plate
Through-hole 1 is opened up, stainless steel plate is fixed on the cap locations of Crankarm box 4, the speed measuring position of through-hole one and connecting lever 5 by screw 3
501 is corresponding, and the diameter of through-hole one is adapted with the outer diameter size of velocity sensor 6.
As preferred embodiments of the present invention, stainless steel plate with a thickness of 3mm.
As preferred embodiments of the present invention, the shape of stainless steel plate and the cover board shape of Crankarm box are identical.
As preferred embodiments of the present invention, through-hole 27 is set, screw passes through through-hole two and turns on stainless steel plate
The threaded hole 8 of arm box connects.
The utility model it is a kind of improve HGIS breaker test the speed accuracy device application method are as follows:
1, the cover board for removing Crankarm box on breaker 10 manually adjusts the position of stainless steel plate, by the biography that tests the speed of velometer 9
Sensor passes through through-hole one and docks with the speed measuring position of connecting lever；
2, after the completion of docking, stainless steel plate is taken advantage of a situation and is covered on the cap locations of Crankarm box, is screwed；
3, after the completion of fixed, operation of testing the speed can be entered.
Although those familiar with the art answers the foregoing describe specific embodiment of the present utility model
Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model
Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should
