Abstract
The invention discloses chopper and switch cubicle dynamic/static contact Bite size measuring appliance in a kind of switch cubicle, including measuring basis dish, telescopic joint, stationary spring and base, described base is cylindrical, it is provided with stationary spring on the both sides of base, base top is provided with telescopic joint, and the upper end of telescopic joint is provided with the measuring basis dish of circle；Described stationary spring is "eight" shape, has arc convex at the middle part of stationary spring.The present invention can be fixed in the conductive wall of switch cubicle easily, by using conductive wall as measure working material, static contact promotes measuring basis dribbling to move telescopic joint motion, thus the distance reaching measuring basis dish and fingertip contact point is exactly this phase chopper and switch cubicle dynamic/static contact Bite size.
Description
Technical field
The invention belongs to power system measuring field of tool, be specifically related to chopper in a kind of switch cubicle and nibble with dynamic/static contact
Close dimension measuring instrument.
Background technology
Currently for measuring chopper and switch cubicle dynamic/static contact Bite size, also there is no a kind of effective method
And utensil, the way of producer is: smear vaseline on static contact, then chopper is advanced operating position, when static contact inserts
During moving contact, the vaseline on static contact surface can mark the marking, then pull out chopper, measure static contact surface vaseline
The marking determine dynamic/static contact Bite size.Although this method is simple, but it cannot be guaranteed that marking size accurate, and this side
Method can only measure in the case of bus all has a power failure, and have impact on production efficiency.
Summary of the invention
The present invention is to solve the problems referred to above, it is provided that one can also be broken to 6～35kV under the charged ruuning situation of bus
The utensil that road device measures with switch cubicle dynamic/static contact Bite size, and safe and reliable, easy and simple to handle.
The technical solution used in the present invention is: in a kind of switch cubicle, chopper is measured with switch cubicle dynamic/static contact Bite size
Utensil, including measuring basis dish, telescopic joint, stationary spring and base, described base is cylindrical, sets on the both sides of base
Having stationary spring, base top to be provided with telescopic joint, the upper end of telescopic joint is provided with the measuring basis dish of circle；Described fixing bullet
Reed is "eight" shape, has arc convex at the middle part of stationary spring.
The beneficial effect comprise that: the present invention can be fixed in the conductive wall of switch cubicle easily, by inciting somebody to action
Conductive wall is as measuring working material, and static contact promotes measuring basis dribbling to move telescopic joint motion, thus reaches measuring basis dish
It is exactly this phase chopper and switch cubicle dynamic/static contact Bite size with the distance of fingertip contact point.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the duty one of the present invention；
Fig. 3 is the duty two of the present invention.
Detailed description of the invention
The present invention is a kind of for measuring chopper and the measuring appliance of dynamic/static contact Bite size in switch cubicle, such as Fig. 1
Shown in, this utensil includes with lower component: cylindrical base 4, stationary spring 3, telescopic joint 2 and measuring basis dish 1, wherein fixes
Spring leaf 3 is fixed on the both sides of cylindrical base 4 in "eight" shape, and it is convex that the middle part of each stationary spring 3 is designed with arc
Rise, be used for increasing contact area, improve fixed effect.Telescopic joint 2 is arranged on base upper surface, and the measuring basis dish 1 of circle
It is arranged on the top of telescopic joint 2, for contacting with static contact.
The handcart of chopper in use, as shown in Figures 2 and 3, is first pulled to overhaul position, by measuring device by the present invention
Tool 6 puts into the moving contact 5 of switch cubicle, utilizes moving contact 5 as the carrier of measuring appliance 6, and now measuring appliance 6 is by two
Stationary spring card 3 in moving contact 5, the fingertip of Fundamentals of Measurement dish 1 not higher than circuit breaker cart, wheelbarrow switch is normally shaken into
To operating position in switch cubicle, after making the contact fingertip of wheelbarrow switch contact with switch cubicle static contact 7, static contact 7 again with measurement
Base plate contacts, and wheelbarrow switch moves on and makes telescopic joint 2 be compressed, then wheelbarrow switch is shaken out, is pulled to overhaul position, measures
Reference disk 1 and the Bite size that the distance disposing contact point is exactly this phase chopper and switch cubicle moving contact 5 contact.
The present invention also is able to accurately obtain measurement data in the case of bus charging operation, by accurately measuring chopper
Judge whether equipment has the potential risk of loose contact with switch cubicle dynamic/static contact Bite size, reduce unit exception and accident
Rate.Simple structure of the present invention, easy to use, measure accurately, significantly reduce the workload of maintainer.
