Abstract
The utility model discloses a three-position indicating mechanism of a drawer circuit breaker. The three-position indicating mechanism comprises a drawer seat and a driving mechanism which is disposed on the bottom of the drawer seat and which is used for driving the circuit breaker drawer. A pair of rotating sector gears meshed with each other are disposed on a wall plate on two sides of the drawer seat. The sector gears include a driving sector gear driven by the driving shaft of the driving mechanism and a driven sector gear driven by the driving sector gear. Three microswitches arranged around the driven sector gear indicate a separating position, a testing position, and an operating position, respectively. Protruding parts arranged on the body of the driven sector gear activate corresponding microswitches at the separating position, at the testing position, and at the operating position, respectively. The three-position indicating mechanism has characteristics of simple structure, easy production, and high reliability of position indication.
Description
Technical field
The utility model relates to a kind of withdrawable circuit breaker three position indicating devices, belongs to the low voltage power transmission equipment technical field.
Background technology
The withdrawable circuit breaker of commonly using at present, it generally comprises two parts, fixing drawout chassis and the breaker body of drawer type; Circuit on the drawout chassis links to each other with main circuit, circuit on the breaker body links to each other with external circuit, withdrawable circuit breaker generally includes separation position ﹑ test position and puts these three positions, ﹑ service position when working, and General Requirements needs accurately to provide the node of indicating withdrawable circuit breaker three position operating states in real work.Three position indicating devices of withdrawable circuit breaker of the prior art, formed by the mechanism on the breaker body and drawout chassis mechanism, realize the indication of circuit breaker three positions by the sensitive switch that the drive disk assembly in the breaker body mechanism drives in the drawout chassis mechanism.Since the sensitive switch in the plate in the breaker body mechanism and the drawout chassis mechanism to be connected the cooperation precision prescribed higher, easily to occur driver part action in the process not in place or cross the position so shake at circuit breaker, cause the situations such as sensitive switch damage, position misregister, Reliability of Microprocessor is low.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of compact conformation, easily manufactured, high withdrawable circuit breaker three position indicating devices of position indication reliability.
In order to solve the problems of the technologies described above, withdrawable circuit breaker three position indicating devices of the present utility model, what comprise drawout chassis and be arranged on the drawout chassis bottom is used for the driving into mechanism of circuit breaker drawer; Being provided with the sector gear of a pair of intermeshing rotation on the wallboard of drawout chassis both sides, is respectively to drive driven off by shaft active sector gear by driving into mechanism, and the driven sector gear that is driven by the active sector gear; The periphery of described driven sector gear is provided with three and is used to refer to respectively the sensitive switch that separates position ﹑ test position and service position, is provided with on the matrix of described driven sector gear to separate the jut that triggers respectively corresponding sensitive switch on position ﹑ test position and the service position.
The utility model is simple in structure, reliable in action; By cooperating sensitive switch to gather the position signalling of circuit breaker with driving into the sector gear of mechanism's through transport of drawer circuit breaker, its gear and sensitive switch can be contained in the laterally compressed space of drawout chassis, and based structures is compact, space hold is little; Because gear drive has higher precision, thereby has improved pointing accuracy.

Embodiment
Below in conjunction with the drawings and specific embodiments, withdrawable circuit breaker three position indicating devices of the present utility model are described in further detail.
As shown in the figure, withdrawable circuit breaker three position indicating devices of the present utility model, comprise drawout chassis and be arranged on the driving into mechanism of drawout chassis bottom, be provided with intermeshing active sector gear 2 and driven sector gear 3 on the wallboard 1 of drawout chassis both sides, drive into mechanism and drive initiatively sector gear 2 rotations in the circuit breaker drawer driving, initiatively sector gear 2 drives driven sector gear 3 rotations, the periphery of driven sector gear 3 is provided with three sensitive switches 4, is respectively applied to indication and separates position ﹑ test position and service position.Be provided with on the matrix of driven sector gear 3 and can separating three juts 5 that trigger respectively corresponding sensitive switch on position ﹑ test position and the service position.
Claims (1)
1. withdrawable circuit breaker three position indicating devices, what comprise drawout chassis and be arranged on the drawout chassis bottom is used for the driving into mechanism of circuit breaker drawer; It is characterized in that: being provided with the sector gear of a pair of intermeshing rotation on the wallboard of drawout chassis both sides (1), is respectively to drive driven off by shaft active sector gear (2) by driving into mechanism, and the driven sector gear (3) that is driven by the active sector gear; The periphery of described driven sector gear is provided with three sensitive switches (4) that are used to refer to respectively separation point position, test position and service position, is provided with on the matrix of described driven sector gear (3) to separate the jut (5) that triggers respectively corresponding sensitive switch on position ﹑ test position and the service position.
