The utility model relates to a kind of electromagnetic type low-voltage power switch; be widely used in the plant equipment of departments such as railway, industrial and mining enterprises, building; be used for protection, control, conversion and connection; disconnect the hydraulic electromagnetic breaker that power supply uses, and can be used as the protection device use of the mechanical, electrical device of line electricity.
Existing low-voltage circuit breaker has only protection, control action, can be switched on or switched off power supply, but also with nowhere to turn to alert function, therefore can't in time notify user, fast processing fault.
The purpose of this utility model is to provide a kind of hydraulic electromagnetic breaker, except that having the circuit breaker function, also has alarm device, in the moment of circuit breaker deenergization, can connect alarm switch rapidly, sends sound, light alarm, uses safer.
The utility model is achieved in that hydraulic electromagnetic breaker is by at cap, install in the housing, the iron core of belt coil respectively with fixed mount, pole shoe connects, dead man, movable contact spring, pole shoe and strap cam, the armature of spring is connected on the fixed mount, bending connecting rod and movable contact spring, the connecting lever connecting rod connects, connecting lever connecting rod end in addition is connected with dead man, coil is respectively with binding post with drive the contact, the movable contact spring of spring connects, and static contact and another binding post of band fixed contact connect and compose electromagnetic switching device, also comprise by the fixed contact lead-out tablet that has fixed contact, two binding posts in one end of moving contact lead-out tablet and the shell are connected, end is installed in the switch housing in addition, spring joins together moving contact lead-out tablet and movable contact spot film, swing sheet one end is fixed on the switch housing, and cooperates the alarm switch that constitutes with button.
Fig. 1. structural representation of the present utility model (take away cap, cover cap is the operating state of circuit breaker).
Fig. 2. structural representation of the present utility model (taking away cap, cover cap is that circuit breaker disconnects, and alarm switch closes).
Fig. 3. alarm switch structure amplification view among Fig. 1.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
The two ends of bending connecting rod (19) use bearing pin to be connected with movable contact spring (18), connecting lever connecting rod (6) respectively, and the end in addition of connecting lever connecting rod (6) is connected with dead man (7) with bearing pin.
The armature (3) of dead man (7), movable contact spring (18), pole shoe (4) and strap cam (29), spring is connected on the fixed mount (5) with bearing pin.
Iron core (20) two ends of belt coil (2) are connected with pole shoe (4) with fixed mount (5) respectively, the two ends of coil (2) is connected with the movable contact spring (18) that drives contact (17), spring with binding post (1) respectively, connect in aggregatesly, and another binding post (1) on static contact (15) and housing (21) back side of band fixed contact (16) connects and composes electromagnetic switching device.
The electromagnetic switching device that has assembled is put into housing (21) location, put division board (13), isolate electric arc.Moving contact lead-out tablet (12) is bending shape
, through hole is arranged on it, through hole is arranged on the moving contact (22), be
Shape has a moving contact (23) on two surfaces of one end, an end is two pins that opening is arranged.
The two ends of spring (26) are respectively by the through hole on moving contact lead-out tablet (12) and the movable contact spot film (22), connect in aggregatesly, and two pins on the movable contact spot film (22) are matched with moving contact lead-out tablet (12).
One end of fixed contact lead-out tablet (25), moving contact lead-out tablet (12) respectively with shell (10) in two binding posts (27) be connected, in addition end is installed in the switch housing (11), and makes moving contact (23) and the fixed contact (24) on it and be fixed on the interior banking stop (28) of switch housing (11) corresponding.
Two clamping faces of swing sheet (8) one ends are separately fixed on the projection on the upper and lower surface of switch housing (11), and contact with button (9), and button (9) is placed in the groove on the switch base bottom surface.Switch housing (11), switch base connect into integral body, and constitute alarm switch with the shell (10) of being with binding post (27), are fixed on the upper left corner of housing (21).
Cap is covered on housing (21), and cover cap covers at dead man (7) to be located, and is fixed on housing (21) with rivet and goes up (figure omits) circuit breaker and be assembled into, just can use.
As shown in Figure 1, two power lines connect two binding posts (1) respectively during normal operation of circuit breaker, and movable contact spring (18) and static contact (15) are by dynamic and static contact (17), (16) adhesive on it.And dead man (7) is disconnected with swing sheet (8) disengaging.
When the circuit overload operation, when surpassing the load current value of circuit breaker, the iron core (20) that is connected with the hydraulic circuit damper tube moves up, magnetic force strengthens, adhesive armature (3), and by promotion connecting lever connecting rod of the cam (29) on it (6) rotation, make the movable contact spring (18) of connected dead man (7) and drive contact (17) simultaneously, clockwise direction rotates an angle in arc-chute (14), the contact that breaks away from the static contact (15) of the band fixed contact (16) that is connected with power supply, deenergization as shown in Figure 2, at this moment an end of dead man (7) contacts with swing sheet (8), and promote button (9) left, button (9) is moved to the left and just promotes that spring (26) moves and drive movable contact spot film (22) and also be moved to the left, moving contact (23) on it is contacted with fixed contact (24) on the fixed contact lead-out tablet (25) and make the alarm switch conducting, make connected acousto-optic device luminous, sounding carries out sound and light alarm.
After fault is got rid of, just can stir dead man (7) left, make it be returned to original operating state, at this moment dead man (7) breaks away from and swings contacting of sheet (8), and alarm switch is not just worked, and circuit breaker can work on again.
The utility model is compared with prior art: because having increased alarm switch at original breaker, just increase Add alarm function, when circuit is out of order, just can in time carry out audible and visual alarm, notified the user in time to locate The reason fault, so it is more reasonable than original circuit breaker design of the same type, uses safer.
