Abstract
The utility model discloses a grasp moulded case circuit breaker's manual tripping device with electricity, a serial communication port, including the release lever, the one end of release lever is dropout button grabbing portion, the other end of release lever is rotatory fixed through the pivot, make the release lever circle a luffing motion, the one end of extension spring of reseing is connected and to be fixed the middle part at the release lever, the other end and electric operating mechanism's the mounting panel of extension spring of reseing is connected fixedly, open porosely on the mounting panel, electric operating mechanism's dropout push rod passes and supports the release lever behind the hole, promote the release lever touched moulded case circuit breaker until the dropout button grabbing of release lever portion around axle downward swinging trip push button by the dropout push rod. The utility model provides an also installed behind the electricity behaviour can the operating breaker trip push button the mechanism, this mechanism structure is simple, and can not take place to interfere mutually with electricity behaviour and circuit breaker.
Description
Technical field
This utility model is related to a kind of band motor-operating mechanism (hereinafter referred to as " electricity behaviour "), and breaker of plastic casing is (hereinafter referred to as
" chopper ") hand tripping mechanism, belong to low voltage electrical apparatus technology field.
Background technology
Low-voltage circuit breaker mainly undertakes the overload of distribution line and electrical equipment, under-voltage, short-circuit protection are used.At some
Special occasions, should have overload and short-circuit protection function with the chopper in electric line, as electrical equipment, motor or generating
The overload of machine circuit and short-circuit protection, and can under normal operation infrequently make-and-break contact be used.
The chopper of some specific uses, in working order under, should ensure that its normal power supply is unaffected.For some weights
Want the circuit of purposes, even if overload even short trouble in special state, chopper still should ensure that power supply, can not thread off
Disconnect.
Electricity grasps the external accessory for chopper, for far distance automatic separating brake and combined floodgate chopper it is adaptable to automatization's journey
Spend higher place.
The hand tripping mechanism of chopper is used for testing the cooperation of circuit breaker operation mechanism and breaker tripping mechanism.
Content of the invention
The purpose of this utility model be provide a kind of install electricity behaviour after also can operating breaker trip push button mechanism.
In order to achieve the above object, the technical solution of the utility model there is provided a kind of handss of powered behaviour's breaker of plastic casing
It is characterised in that including release lever, one end of release lever is trip push button operating portion to dynamic tripping mechanism, the other end of release lever
Fixed so that release lever swings up and down around the shaft by rotating shaft rotation, one end of reset tension spring is fastened in release lever
Portion, the other end of reset tension spring is connected with the installing plate of motor-operating mechanism, has hole, electric operating machine on a mounting board
The dropout push rod of structure props up release lever after passing through hole, promotes release lever de- up to release lever around axial lower swing by dropout push rod
Button button-operating portion touches the trip push button of breaker of plastic casing.
Preferably, the screw fixed by nut is equipped with one end of described release lever, described release lever is on screw
Lower swing.
This utility model provide a kind of install electricity behaviour after also can operating breaker trip push button mechanism, this mechanism tie
Structure is simple, and will not interfere with each other with electricity behaviour and chopper.
Brief description
The structural representation of the hand tripping mechanism of a kind of powered behaviour's breaker of plastic casing that Fig. 1 provides for this utility model；
Fig. 2 is arranged on the schematic diagram after the installing plate of electricity behaviour for this utility model；
Fig. 3 is operation chart of the present utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage more understand understandable, to combine instantiation, to this
Utility model further describes.
As shown in figure 1, a kind of powered hand tripping mechanism grasping breaker of plastic casing that this utility model provides includes nut
1st, screw 2, release lever 3, reset tension spring 4.Screw 2 passes through the rotating hole of release lever 3, then the installing plate 6 grasped by electricity, and gap is joined
Close, can then use nut 1 fixing with flexible rotating.
In conjunction with Fig. 2, the lower end circular hole of release lever 3 installs reset tension spring 4, and the upper end of reset tension spring 4 is hung in the installation of electricity behaviour
On plate 6.The mechanism that this practicality provides is directly installed under installing plate 6, between the installing plate 6 of chopper and electricity behaviour.Knot
Close Fig. 3, perforate 7 on installing plate 6, the dropout push rod 8 that electricity behaviour carries can be made to pass through, act on the upper end of release lever 3.Reference
Lever principle, grasps the downward power of the dropout push rod 8 carrying using electricity, provides moment, so that release lever 3 is revolved around the screw 2 positioning
Turn, after release lever 3 rotation, front end is applied to downwards the trip push button 9 of chopper, makes circuit breaker tripping.Reset tension spring 4 is in order to de-
The reset of button bar 3.
Although this utility model with reference to examples detailed above, this utility model to be described it should be understood that wherein can make various changes and
Modification and in a broad sense without departing from this utility model, so being not intended as this utility model is limited, as long as in this practicality newly
In the spirit of type, change to embodiment described above, deformation falls within this utility model claim
Protection domain.
