Abstract
The utility model discloses a residual-current circuit breaker including a shell and a movable press button spring. The movable press button spring is clamped in a press button spring. One end of the movable press button spring is connected with a lead while the other end of the movable press button spring is contacted with a static press button sheet when the movable press button spring is closed. An N static contact on a shell of the residual-current circuit breaker is provided with an arc extinguishing shade. The arc extinguishing shade is arranged on the top of an arc striking sheet. One end of the arc striking sheet is connected with a conductor and is also connected with an end of an N static contact lead. And the shell is made of transparent material. The arc distinguishing shade is disposed in an arc distinguishing chamber that is of a double-layer structure. The residual-current circuit breaker provided by the utility model has beneficial effects that people can know statuses of a leakage protector timely and make judgments timely since the residual-current circuit breaker is reasonable in design; inner condition can be known conveniently since the shell is made of the transparent material, so that maintenance is facilitated and maintenance time is reduced; and electricity utilization safety factors are increased, so that using safety is improved.
Description
Technical field
The utility model relates to breaker technical field, particularly a kind of residual current circuit breaker.
Background technology
At present; it is very much inconvenient wanting to understand inner situation at existing common earth leakage protective device; when people need understand inner case; the shell of also will dismantling; so not only waste time and energy; and this has also brought many inconvenience for safety utilization of electric power and maintenance, can't satisfy modern people's user demand.
The utility model content
At the deficiencies in the prior art, the utility model provides a kind of residual current circuit breaker.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
Residual current circuit breaker, comprise shell and button, button snap is on moving button spring, and moving one of button spring connects lead, the other end touched quiet button piece when moving button spring was closed, N fixed contact on the residual current circuit breaker shell is provided with arc-extinguish chamber, and arc-extinguish chamber withstands on the striking sheet, and one of striking sheet is connected with conductor, also be connected with N fixed contact lead one end, and shell is that transparent material is made, and arc-extinguish chamber is positioned at arc control device, and arc control device are double-decker.
Described button left direction is provided with an indicator light.
The beneficial effects of the utility model: this utility model is reasonable in design, makes people can in time understand the state of earth leakage protective device, in time judges; Because shell is to be made of transparent material, understands inner case very easily, thereby be conducive to maintenance, reduced the time of maintenance; Increase the coefficient of Electrical Safety, be conducive to people's use safety.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of residual current circuit breaker comprises shell 10 and button 20, and button 20 is stuck on the moving button spring, moving one of button spring connects lead, the other end touched quiet button piece when moving button spring was closed, and the N fixed contact on the residual current circuit breaker shell is provided with arc-extinguish chamber, and arc-extinguish chamber withstands on the striking sheet, one of striking sheet is connected with conductor, also be connected with N fixed contact lead one end, and shell 10 is for transparent material is made, described button 20 left directions are provided with indicator light 30.Arc-extinguish chamber is positioned at arc control device, and arc control device are double-decker, and arc control device are N utmost point arc extinguishing, and another is L utmost point arc extinguishing.The beneficial effects of the utility model: this utility model is reasonable in design, makes people can in time understand the state of earth leakage protective device, in time judges; Because shell is to be made of transparent material, understands inner case very easily, thereby be conducive to maintenance, reduced the time of maintenance; Increase the coefficient of Electrical Safety, be conducive to people's use safety.
