Abstract
The invention discloses a measurer for the stroke of moving and fixed contacts of a middle-placed switch cabinet handcart switch. The measurer comprises upper and lower ring-shaped bases which are opposite to each other, wherein flexible chains are connected between the two ring-shaped bases; each ring-shaped base comprises flexible chain seats arranged at intervals; an adjusting plate is movably connected between two adjacent flexible chain seats; and the flexible chains are positioned between two flexible chain seats corresponding to the two bases. The measurer has the advantages of simple structure and capacity of measuring the stroke of the moving and fixed contacts of the middle-placed switch cabinet handcart switch.
Description
Technical field
The present invention relates to mid-cabinet field, especially relate to a kind of wheelbarrow switch dynamic/static contact stroke measurment device.
Background technology
The high-tension switch cabinet of promoting in the electric system is the mid-cabinet of Totally-enclosed-type, mid-cabinet is when acceptance and distribution network electric energy, the operation of main dependence wheelbarrow switch in cabinet, wheelbarrow switch are shaken into dynamic/static contact contact in the cabinet, at this moment, major loop is connected, switch is in the working position, can close, divide operation to it by control loop, if dynamic/static contact inserts stroke when not enough, just cause loose contact, safe operation is a hidden danger to switch cubicle.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, can measure the measuring appliance of mid-cabinet wheelbarrow switch dynamic/static contact stroke.
For achieving the above object, the present invention adopts following technical scheme: a kind of mid-cabinet wheelbarrow switch dynamic/static contact stroke measurment device, comprise two annular bases that are oppositely arranged up and down, be connected with flexible chain between two annular bases, described annular base comprises the flexible chain seat that is provided with at interval, be connected with adjustable plate between the two adjacent flexible chain seats, described flexible chain is between two bases corresponding two flexible chain seats.
Described flexible chain seat and adjustable plate are arc, and the two ends of flexible chain seat all are provided with traveller, and the equal corresponding traveller in the two ends of adjustable plate is provided with the chute of arc.
Described flexible chain seat is a hollow-core construction, and the both ends of adjustable plate are positioned at adjacent two flexible chain seats respectively.
Flexible chain seat and adjustable plate on described each base are four, and are circular arc.
The inner lane of the flexible chain seat protection ring that all has been sticked.
Described flexible chain seat and adjustable plate are circular arc, and annular base inner ring minimum diameters that both form are 35mm, and maximum gauge is 120mm; The minimum altitude of the measuring appliance of being made up of two annular bases and flexible chain is 80mm, and maximum height is 120mm.
Mid-cabinet wheelbarrow switch dynamic/static contact stroke measurment device of the present invention, flexible chain seat and adjustable plate can be adjusted self diameter according to the diameter of static contact, and flexible chain adopts the parallelogram principle cross connection, and is flexibly flexible, flexible stroke is big, can be convenient for measuring set out, static contact forms.Protection ring can protect flexible chain seat inboard not worn and torn by static contact.This product also has compact conformation, and is easy to adjust, flexibly flexible, the advantage that maintenance is few.
