Abstract
The utility model relates to a new open and cut-off interlocking device for a power switch, which is mainly composed of a rotary handle, a lock, a shifting fork, an installation plate, a door hook, etc. The device is arranged on the side surface of the power switch, and the installation type is clamp rail type. The moving track of the shifting fork and the handle of the power switch is a concentric circle. The device forms a complete power switch with interlocking with the series, such as C45, NC100, DZ63, etc. The utility model has the advantages of strong versatility, simple installation and small volume. The use is more convenient for the user, and particularly, high safety is brought for the operator. The utility model is suitable to match with various electric boxes (cabinets) having different sizes, specifications and kinds, and the application is wide.
Description
The utility model relates to a kind of improved electric control box (cabinet) door opening electrical outage interlock.This device requires design according to national standard (GB5226--85), has to use more conveniently, installs simplyr, and highly versatile especially brings safer to the operator.Be suitable for the supporting use of electric cabinet (cabinet) that all size does not wait the specification kind, use face is very extensive.
At present, known this device is mainly by rotary handle, shift fork, installing base frame, key and gate stop are formed the front that is installed in mains switch (air switch, isolating switch), rotate rotary handle by staff and realize the function that disconnected lock, combined floodgate, the Men Kaihou of door opening electrical outage and mains switch can not close a floodgate by middle link gear drive displacement shift fork.Because mainly there is the shortcoming of two aspects in the device of above structure:
One, the movement locus of this device shift fork is a straight line, and handle is to rotatablely move.Both must realize its action by the centre switching mechanism that links.Therefore, the part number of whole device is more, mechanism's complexity, and the cost height is installed inconvenience etc.
Two, this device is installed in the front of mains switch.Therefore, be subjected to the influence of the serial size of mains switch (air switch, isolating switch), this device kind specification series is various accordingly, to user's type selecting, installation, very inconvenience of use.
The purpose of this utility model provides a kind of mains switch door opening electrical outage interlock of novelty.It not only overcomes the shortcoming of being narrated, but also has overcome shortcoming two.
The purpose of this utility model realizes that like this this device is installed in the mains switch side, rotary handle, and the movement locus of the handle of shift fork and mains switch is a concentric circles, does not have intermediate conversion mechanism.Advantages such as therefore, it is less that this device has the part number, and mechanism is simple.
When staff rotates this device handle, the concentric garden track that directly drives the handle of mains switch by shift fork rotates disconnected lock and the combined floodgate of realizing door opening electrical outage and mains switch, the function that Men Kaihou can not close a floodgate.Therefore, when adopting this scheme to realize its function, be not subjected to the influence of mains switch (air switch, isolating switch) number of poles.This device and C45N, NC100, serial air such as DZ63, isolating switch are formed a mains switch band interlock, has volume little (have only old product 1/3rd), low cost of manufacture, install easily, series of products have only two specification kinds, ten above specifications of kind of old product.Simple in structure, highly versatile, type selecting is convenient.
Owing to adopt such scheme, with the shift fork and the mains switch handle coupling of this device,, finished supporting versatility easily with serial all sizes such as C45N, NC100, DZ63 with the concentric tracks motion.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the A--A profile of Fig. 2;
Fig. 2 is the side-looking structural map of mains switch interlock;
Fig. 3 is that the B of Fig. 2 is to partial sectional view;
［ 1 ］ mounting panel ［ 2 ］ shift fork ［ 3 ］ spring ［ 4 ］ drive plate ［ 5 ］ gate stop ［ 6 ］ indication panel ［ 7 ］ rotary handle and lock among the figure, double dot dash line place is a mains switch.
In embodiment illustrated in fig. 2, rotary handle and lock (7) drive plate (4) shift fork (2) mounting panel (1) has been formed a rotatable unit, drives the mains switch handle and realizes its function.The pulling force of spring (3) guarantees the dynamics of circling round of shift fork (2).The section of shift fork (2) is a flute profile as can see from Figure 1, and the outside is open shape.Therefore, can pitch handle easily into mains switch.Mains switch and this device take clamping-rail to install.
Claims (4)
1, a kind of mains switch interlock mainly contains compositions such as rotary handle and lock, shift fork, mounting panel and gate stop, and it is characterized in that: this device is installed in the side of mains switch.
2, this device according to claim 1 is characterized in that: mains switch and this device take clamping-rail to install.
3, this device according to claim 1 is characterized in that: the movement locus of shift fork and mains switch handle is a concentric circles.
4, this device according to claim 3 is characterized in that: the section of shift fork is a flute profile, and the outside is open shape.
