Abstract
The utility model belongs to the electrical field, in particular relates to a shell type circuit breaker. The shell type circuit breaker comprises a shell and an operating mechanism, the shell is provided with a contact which is hinged in the shell body, the contact is connected with the operating mechanism, the driving end of the operating mechanism is arranged on the shell. The circuit breaker also comprises a contact open indication rod, the contact open indication rod is slidably connected with the shell, the upper end of the contact open indication rod is arranged outside the shell, and the lower end of the contact open indication rod is arranged on the movement path of the contact. When the contact rotates, the contact open indication rod is driven to move, an operator can easily judge the working state of the shell type circuit breaker according to the position of the upper end of the contact open indication rod, so that the function of the shell type circuit breaker is more complete, and the structure layout is more reasonable.
Description
Technical field
The utility model relates to electric field, refers to especially a kind of casing type circuit breaker.
Background technology
Casing type circuit breaker is generally used as distribution, also can be the use of protection motor, under normal circumstances, circuit breaker can be respectively as the use of the not frequent transitions of circuit and the not Fraquent start of motor.And existing casing type circuit breaker comprises housing and be positioned at the break-make loop of housing, in use, whether operator can not differentiate this casing type circuit breaker easily in running order, only have whether in running order by this residual current circuit breaker of position judgment of operating mechanism, if in the situation that operating mechanism is malfunctioning, operator is easily misjudgement just, has potential safety hazard in operating process.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of in running order casing type circuit breaker that is easy to judge whether.
The technical solution of the utility model is achieved in that a kind of casing type circuit breaker, comprise housing and operating mechanism, in described housing, be provided with contact, this contact is articulated with in housing, and this contact is connected with operating mechanism, and the drive end of operating mechanism is arranged on housing, also include contact and disconnect indicating arm, this contact disconnects indicating arm and is slidably connected with housing, and the upper end that contact disconnects indicating arm is positioned at outside housing, and the lower end of contact disconnection indicating arm is positioned on the motion path of contact.
By adopting technique scheme, when contact when rotated, drive contact to disconnect indicating arm motion, operator can disconnect the operating state of this casing type circuit breaker of position judgment of indicating arm upper end easily by contact, make the function of casing type circuit breaker more complete, topology layout is more reasonable.
The utility model is further set to: described contact disconnects on indicating arm and is provided with resetting device.
As preferably, described resetting device comprises spring and centring ring, and described centring ring is fixed on the middle part that contact disconnects indicating arm, and the two ends of spring contact with housing with centring ring respectively.
As preferably, described spring housing is located at contact and is disconnected on indicating arm.
By adopting technique scheme, contact disconnects indicating arm under the effect of spring, play the effect of reset, make the motion state of contact disconnection indicating arm more reasonable, avoid in motion process, blocking because contact disconnects indicating arm the error existence that causes indicating effect.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model embodiment structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model discloses a kind of casing type circuit breaker, comprise housing 1 and operating mechanism 3, in described housing 1, be provided with contact 2, this contact 2 is articulated with in housing 1, and this contact 2 is connected with operating mechanism 3, the drive end of operating mechanism 3 is arranged on housing 1, at this, use in novel specific embodiment, also include contact and disconnect indicating arm 4, this contact disconnects indicating arm 4 and is slidably connected with housing 1, and the upper end that contact disconnects indicating arm 4 is positioned at outside housing 1, the lower end that contact disconnects indicating arm 4 is positioned on the motion path of contact 2, when contact 2 when rotated, drive contact to disconnect indicating arm 4 motions, operator can disconnect the operating state of this casing type circuit breaker of position judgment of indicating arm upper end easily by contact, make the function of casing type circuit breaker more complete, topology layout is more reasonable.
At this, use in novel specific embodiment, described contact disconnects on indicating arm 4 and is provided with resetting device, resetting device described in the utility model comprises spring 6 and centring ring 5, described centring ring 5 is fixed on the middle part that contact disconnects indicating arm 4, described spring 6 is sheathed on contact and disconnects on indicating arm 4, the two ends of spring 6 contact with housing 1 with centring ring 5 respectively, contact disconnects indicating arm 4 under the effect of spring, play the effect of reset, make the motion state of contact disconnection indicating arm 4 more reasonable, avoid in motion process, blocking because contact disconnects indicating arm the error existence that causes indicating effect.
This casing type circuit breaker in the course of the work, when casing type circuit breaker is during in off-state, contact pushes contact and disconnects indicating arm direction outside housing and slide, and the upper end that now contact disconnects indicating arm is positioned at outside housing, operator just known this casing type circuit breaker in off-state; When casing type circuit breaker is during in on-state, contact disconnects indicating arm under the effect of spring, and to the direction motion of enclosure interior, contact disconnects indicating arm with contact and do not contact, and now contact disconnection indicating arm is absorbed in housing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
