Described mechanism case is provided externally with a deciliter pointer.
The permanent-magnet type post load switch of employing permanent-magnet type operating mechanism of the present utility model, function admirable, permanent-magnet type operating mechanism simple and reliable for structure is adopted to drive switch to carry out a deciliter operation, thus forming a kind of novel permanent-magnet type post load switch, former FZW28 type post load switch can be substituted completely.
Function of the present utility model and advantage:
1. switch can carry out manual divide-shut brake, electronic breaking-closing operating, and function is more perfect;
2. construction of switch is simple, and trouble point greatly reduces, and the fault-free life-span is longer, lower in cost;
3. interchangeability is good, and former FZW28 demarcation switch can directly use this utility model instead, it is not necessary to makes any change;
4. the kinetic characteristic of permanent magnet mechanism more meets the dynamic characteristic (see Fig. 3) of vacuum load switch.
Specific embodiment:
As shown in Figure 4, for the outline drawing of the permanent-magnet type post load switch of employing permanent-magnet type operating mechanism of the present utility model;
As it is shown in figure 5, be the operating mechanism structure chart of on-load switch in this utility model embodiment.
The spring operating mechanism that this utility model switchs principally for FZW28 type has installed permanent magnet driving device additional, and concrete change is as follows:
1. retain in original mechanism the reasonably part such as support, deciliter swing arm (inside connecting breaking-closing operating axle), handle connecting lever, energy-stored spring; The divide-shut brake action of switch is to be controlled by the gathering sill in deciliter swing arm, because this part is not changed by this utility model, thus not reinflated tells about its principle.
2. newly devise interlock between deciliter swing arm and handle connecting lever, Handle axis can be made directly to drive a deciliter swinging arm.
3. install permanent magnet driving device additional, for electronic divide-shut brake.
4. utilize the principle of permanent magnet Guan Bi self-locking, instead of former complexity and insecure closing holding mechanism and manual brake separating mechanism.
5. between handle connecting lever and deciliter swing arm, design has link gear, it may be achieved manual divide-shut brake function.
The operation principle of permanent-magnet type operating mechanism of the present utility model is:
Electric operating:
1. electric switch-on: (Fig. 6) solenoid energising during gate-dividing state, the magnetic field produced superposes with magnetic field of permanent magnet, dynamic iron core produces thrust under field drives, deciliter swing arm is promoted to carry out closing operation by traction casing, also energy-stored spring is compressed energy storage simultaneously, (Fig. 7) the solenoid power-off afterwards that puts in place of closing a floodgate.
2. close a floodgate and keep: close a floodgate after putting in place, dynamic iron core and end plate contact, closed magnetic circuit (Fig. 7 Middle Ring Line) is together form together with cylinder body, permanent magnet, static iron core, magnetic gap is zero, only the magneticaction of permanent magnet just can make both adhesive self-lockings, and the separating brake power that this power produces much larger than energy-stored spring, thus a deciliter swing arm is locked to "on" position
3. electronic separating brake: solenoid is reversely energized, and magnetic field offsets with magnetic field of permanent magnet, permanent magnetism self-lock force disappears, and under the earth pressure release effect of energy-stored spring, deciliter swing arm carries out sub-switching operation
4. separating brake keeps: after separating brake puts in place, deciliter swing arm is pressed in separating brake banking pin place by energy-stored spring, is locked in gate-dividing state
Manual operation:
1. manual brake separating: rotate clockwise Handle axis, handle connecting lever drives deciliter swing arm to rotate by interlock (Fig. 8), overcome permanent magnetism self-lock force, the dynamic iron core promoting permanent magnet mechanism separates with end plate, the closed magnetic circuit of permanent magnet is cut off, self-lock force rapidly disappears, deciliter swing arm energy-stored spring do with under, carry out rapidly sub-switching operation (Fig. 7 state to Fig. 6 state).
2. separating brake keeps: after separating brake puts in place, deciliter swing arm is pressed in separating brake banking pin place by energy-stored spring, is locked in gate-dividing state, and now handle connecting lever resets under energy-stored spring effect, and the Interlock Status between deciliter swing arm is released from (Fig. 9)
3. closing by hand: rotate clockwise Handle axis, during because of separating brake, Interlock Status is released from, so handle connecting lever can cross a deciliter swing arm to the left, energy-stored spring can promote a deciliter swing arm adverse movement, carrying out closing operation, now Handle axis is regardless of resetting (Figure 10)
4. stored energy operation: after closing by hand puts in place, it is necessary to rotate counterclockwise Handle axis, makes Handle axis and connecting lever return to initial combined floodgate and keeps state (Figure 10 state to Fig. 7 state)
5. close a floodgate and keep: after closing by hand puts in place, deciliter swing arm is maintained at "on" position (Fig. 7) because of the self-lock force of permanent magnet mechanism
The effect that this utility model brings:
1. permanent magnetic drive technology has been used in post load switch by this utility model, by custom-designed permanent-magnet type operating mechanism, enormously simplify product structure, enhances product performance, the domestic similar structures but without this respect.
2., because permanent-magnet type mechanism kinematic parts of the present utility model are few, kinetic characteristic is more suitable for the dynamic characteristic of vacuum switch, thus performance is more excellent than existing product, more accords with the demands of the market.
3.FZW28 type switch is the domestic base components just expanding wide intelligent grid in large area, use more the biggest, its security and stability is required more and more higher, thus apply product wide market of the present utility model, existing product can be replaced rapidly after operation, quickly produce good economic benefit.
Core of the present utility model is:
A kind of substituting the novel permanent magnetic type pole vacuum on-load switch of existing FZW28 type pole vacuum on-load switch on scene, switch have employed the permanent-magnet type operating mechanism of simple in construction, dependable performance.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should be encompassed within protection domain of the present utility model. Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
