Abstract

The invention relates to an interlocking device of an electric operating mechanism of an isolating switch; the interlocking device comprises a panel, a bracket, a micro-switch, a bended plate, a shaft sleeve and a handle; the bracket, the micro-switch, the bended plate and the shaft sleeve are installed on the panel; furthermore, the bracket, the micro-switch, the bended plate and the shaft sleeve together form an interlocking mechanism; the bended plate can be driven by the handle to rotate along the axis of the shaft sleeve and shift an idler wheel of the micro-switch to down; a handle insertion hole for the handle to insert is on the side end of the panel; the handle stretches into the panel through the handle insertion hole from outside to inside; and the front end of the handle and the bended plate are matched with each other. When the interlocking device of the electric operating mechanism of the isolating switch is used, switch can be completed only in need of one step; and thus, the interlocking device is very convenient.

Description

A kind of isolating switch motor-operating mechanism interlock

Technical field

The present invention relates to a kind of isolating switch, particularly a kind of isolating switch motor-operating mechanism interlock.

Background technology

Isolating switch (disconnector), namely when dividing position, having the insulation distance of the requirement that conforms with the regulations and significantly disconnecting mark between contact; When co-bit is put, the switchgear of electric current under normal loop condition and the electric current at the appointed time under exceptional condition (such as short circuit) can be carried.Isolating switch (being commonly called as " disconnecting link "), generally refer to high voltage isolator, namely rated voltage is at 1kV and above isolating switch thereof, usually referred to as isolating switch, be use maximum a kind of electrical equipment in high-voltage switch electric appliance, the principles and structure of itself is fairly simple, but due to use amount large, functional reliability requires high, all larger on the impact of the design of electric substation, power plant, foundation and safe operation.The main feature of isolating switch is without arc extinguishing ability, can only divide, closing circuit when not having load current.Isolating switch is used for each step voltage, is used as to change circuit and connects or make circuit or equipment and isolated from power, and it does not stop ability, operate after can only first being disconnected by circuit with miscellaneous equipment again.Generally with the interlock of misoperation when preventing switch band load, sometimes need pin to prevent cut-off switch under the magneticaction of large fault.

At present, the isolating switch in commercially using, its operating mechanism has manual and electronic two kinds of actuating modes that can mutually switch usually.But, when switching, need first by the roller of sensitive switch to pressing down, then handle could action, needs two actions to switch, the trouble compared.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of easy to operate isolating switch motor-operating mechanism interlock.

For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of isolating switch motor-operating mechanism interlock, and its innovative point is: comprise panel, support, sensitive switch, bent plate, axle sleeve and handle;

Described support, sensitive switch, bent plate and axle sleeve are installed on panel, and support, sensitive switch, bent plate and axle sleeve form interlocking device jointly, described bent plate can drive the axis direction along axle sleeve to rotate by handle, and the roller can stirring sensitive switch is descending;

Side on described panel has the handle insert port that an appearance handle inserts, and described handle ecto-entad stretches in panel by this handle insert port, and front end and the bent plate of handle cooperatively interact.

The invention has the advantages that: support, sensitive switch, bent plate and axle sleeve entirety is formed interlocking device, when switching, utilize handle to stir bent plate thus drive sensitive switch roller to press down, switching can be completed, simultaneously bent plate is in closed condition due to Action of Gravity Field always, after handle is extracted, it can set back automatically, and sensitive switch switches back initial configuration simultaneously; Use this device, only need a step action to complete switching, very convenient.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of isolating switch motor-operating mechanism interlock of the present invention.

Fig. 2 is the vertical view of isolating switch motor-operating mechanism interlock of the present invention.

Embodiment

Schematic diagram is as shown in Figure 1 and Figure 2 known, and isolating switch motor-operating mechanism interlock of the present invention comprises panel 1, support 2, sensitive switch 3, bent plate 4, axle sleeve 6 and handle 7.

Support 2, sensitive switch 3, bent plate 4 and axle sleeve 6 are installed on panel 1, and support 2, sensitive switch 3, bent plate 4 and axle sleeve 6 form interlocking device jointly.

Bent plate 4 can drive the axis direction along axle sleeve 6 to rotate by handle 7, and the roller can stirring sensitive switch 3 is descending.

Have the handle insert port 5 of appearance handle 7 insertion at the side of panel 1, handle 7 ecto-entad is stretched in panel 1 by this handle insert port 5, and the front end of handle 7 and bent plate 4 cooperatively interact.

When switching, handle 7 is inserted after in panel 1, bent plate 4 can the axle center along axle sleeve 6 rotates due to the effect of handle 7, the roller finally stirring sensitive switch 3 presses down, thus complete and switch the process of sensitive switch, and bent plate 4 is in closed condition due to its Action of Gravity Field always, when handle 7 is from after panel 1 is extracted, bent plate 4 can automatically reply original position, and sensitive switch 3 switches back initial shape simultaneously.

More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
