Abstract
The utility model discloses a residual current circuit breaker with an indicating device, which comprises an arc extinguish chamber, an operating mechanism, a base, a fixed contact, a movable contact, a handle, a zero sequence current transformer and a leakage tripper. The residual current circuit breaker is characterized by arranging an on-and-off indicating device which comprises an indicating arm and a returning spring, wherein a housing of the indicating device is provided with a through hole, the indicating arm penetrates the through hole and is movably arranged along direction of the through hole and linked with the moveable contact. The residual current circuit breaker with an indicating device has a function of indicating switching state of the residual current circuit breaker, which can effectively avoid safety accidents caused by fault operation.
Description
Technical field
The utility model relates to a kind of circuit breaker, particularly a kind of residual current circuit breaker with indicating device.
Background technology
Existing residual current circuit breaker has generally comprised parts such as comprising arc control device, operating mechanism, pedestal, fixed contact, moving contact, handle, zero sequence current mutual inductor, leakage tripping device.Have short circuit, overload protection function.Existing residual current circuit breaker does not have the break-make deixis, and is accidents caused because of charged misoperation easily.
The utility model content
The purpose of this utility model is to overcome above technological deficiency, and a kind of residual current circuit breaker with band indicating device of indication residual current circuit breaker on-off action is provided.
In order to realize above purpose, the utility model is by the following technical solutions: a kind of residual current circuit breaker with indicating device, comprise arc control device, operating mechanism, pedestal, fixed contact, moving contact, handle, zero sequence current mutual inductor, leakage tripping device, it is characterized in that: described residual current circuit breaker is provided with the break-make indicating device, this indicating device comprises indicating arm and back-moving spring, the housing front is provided with through hole, described indicating arm passes through hole and along the movable setting of through hole direction, indicating arm and moving contact link.
The beneficial effects of the utility model are: the utility model is provided with the indicating arm of indication residual current circuit breaker break-make, and when residual current circuit breaker disconnected, the moving contact rotation promoted indicating arm and stretches out housing, and this is first indicating positions; When residual current circuit breaker is closed, the moving contact counter-rotating, indicating arm resets under the effect of the elastic force of back-moving spring, and this is second indicating positions.The user can know the residing on off operating mode of residual current circuit breaker simply expressly according to the residing position of indicating arm, thereby effectively avoids the security incident that causes because of misoperation.
Further describe below in conjunction with accompanying drawing and embodiment
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is a residual current circuit breaker closure state schematic diagram;
Embodiment
As shown in Figure 1 and Figure 2, a kind of residual current circuit breaker with indicating device comprises arc control device 4, operating mechanism, pedestal, fixed contact, moving contact 5, handle 1, zero sequence current mutual inductor, leakage tripping device.The utility model is provided with the break-make indicating device, and this break-make indicating device comprises indicating arm 3 and back-moving spring 2.Housing is provided with through hole indicating arm 3 and is dumbbell shaped, and the diameter at two ends is greater than the diameter of middle part, and the two ends of indicating arm 3 form a step respectively.The diameter of through hole is consistent with the diameter of indicating arm 3 middle parts.Indicating arm 3 one ends stretch out housing, and the other end stretches in the housing.Back-moving spring 2 is enclosed within indicating arm 3 middle parts, and an end props up housing, and the other end props up the step that indicating arm 3 stretches into enclosure interior.The step that indicating arm 3 stretches out housing cooperates with housing is spacing.When residual current circuit breaker disconnected because of short circuit or overload, moving contact 5 promoted indicating arms 3 to indicating arm 3 directions rotations of living in and forms first indicating positions; When residual current circuit breaker is closed, moving contact 5 opposite spins, indicating arm 3 is under back-moving spring 2 elastic force effects, and the indentation housing forms second indicating positions.
When the utility model used, the user can know the residing on off operating mode of residual current circuit breaker simply expressly according to indicating arm 3 residing positions, thereby effectively avoided the security incident that causes because of misoperation.
Certainly, the utility model loses and is limited to above-mentioned execution mode, and any improvement to the utility model unsubstantiality all should be within the utility model protection range.
Claims (2)
