Abstract

The utility model relates to a single-phase automatic recloser residual-current circuit breaker. A circuit breaker is arranged in a bottom seat (11) and a handle exposes outside a cover. A display window is arranged on the cover surface. An incoming-line pole and an outgoing-line pole (12) are arranged at the two ends of the shell. An integrated circuit board (6) and a mutual inductor are mounted in the shell. An operation circuit is composed of a rectification, filter and voltage-stabilization circuit (13), a signal amplification circuit (14), a reclose control circuit (15) and a separation brake control circuit (16). A micro-processor controls the circuit system. The handle (8) exposes outside a middle cover (10) and an electric machine (9) is mounted on the middle cover (10). The electric machine (9) is connected with the handle (8) by a crank and an opening-closing brake indication rod through hole (2) is arranged on the upper cover (1). The single-phase automatic recloser residual-current circuit breaker is mounted in containers of a workshop type production area and a corridor living area and has advantages of adjustable preset current and strong commonality and solves the problem that the area is not protected by the mated residual-current circuit breaker for a long time.

Description

The single phase autoreclosing residual current circuit breaker

Technical field

The utility model relates to a kind of circuit emergency protective device, specifically is mounted in residual current circuit breaker on the uniline, that have motor-operating mechanism thereby energy automatic reclosing.

Background technology

Existing automatic reclosing residual current circuit breaker is installed on the distribution line of three-phase and four-line, is undertaking the urgent protection task on the more high-power transmission line.And throw light on and the Household Appliance circuit in the family daily life, the family expenses protector that common structure is simple, power is little is made emergency protective device.Fast development along with China's economy and life; the installation of small-sized workshop-based production, residential compound corridor collection table case; the utmost point needs the residual current circuit breaker of the single-phase adjustable of some 50-250 amperes and energy automatic reclosing; to guarantee that these people that belong to no supporting protective device originally gather the safety in district; to this, still belong to blank at present.

The utility model content

The technical problems to be solved in the utility model provides the adjustable single phase autoreclosing residual current circuit breaker of a kind of electric current.

The technical scheme that solves this technical problem is: this single phase autoreclosing residual current circuit breaker, include the moving contact that is installed in the circuit breaker in the base, fixed contact, head, the handle of head is exposed to outside the lid, display window is arranged on the capping, there are inlet wire post and outlet column in the shell two ends, surface-mounted integrated circuit and instrument transformer are installed in the shell, operating circuit is by rectification and filtering and voltage stabilizing circuit, signal amplification circuit, reclosing control circuit and sub-gate control circuit are formed, a micro processor controls Circuits System, shell is by loam cake, middle cover and base three parts are formed, handle is exposed to outside the handle through hole of middle cover, in cover motor also be installed, motor is connected handle by connecting rod with crank, on cover in addition divide-shut brake indicating arm through hole, the status indicator lamp hole, manual brake separating through hole and button.

Said circuit breaker is a CM1-250 type circuit breaker.Said motor is that 49TYD-500-1 type, power 4W, rotating speed are the motor of 2.6r/min.

The beneficial effects of the utility model are to make to be in remote mountain areas, island to be developed, single household only family, village and the workshop-based enterprise in town and country and the collection table case of the many resident families of corridor of logical single phase circuit; supporting circuit emergency protective device has been arranged; and because of the rated current of this device can be regulated highly versatile in the 50-250A scope.
