Among the figure: the 1-closing coil, the 2-permanent magnet, the 3-isolating diode, 4-is adjustable separating brake extension spring, 5-permanent magnet mechanism housing, 6-moves iron core, 7-linkage, 8-contact compression spring, 9-switching winding, 10-power switch end, the under-voltage power end of 11-, the under-voltage coil of 12-
Embodiment
Embodiment 1:
As shown in Figure 1, the utility model has a permanent magnet mechanism housing 5,5 are provided with moving iron core 6 in the permanent magnet mechanism housing, the adjustable permanent magnet 2 of switching winding 9 and piece number, 6 times exits of said moving iron core are connected to linkage 7, be connected with adjustable separating brake extension spring 4 and contact compression spring 8 on the said linkage 7, the bottom is provided with under-voltage coil 12 and closing coil 1 in permanent magnet mechanism housing 5, said under-voltage coil 12 and closing coil 1 are one, and the exit of under-voltage coil 12 and closing coil 1 is drawn under-voltage power end 11 and power switch end 10 respectively, between under-voltage power end 11 and power switch end 10, be connected to isolating diode 3, so that under-voltage power supply and power switch can be added in simultaneously is under-voltage, on the closing coil 1.
By the adjustment of permanent magnet 2 and tripping spring, make circuit breaker in operating temperature range, can remain on closing position.After connecting under-voltage power supply, when supply voltage was lower than 35% rated voltage, circuit breaker can not remain on the closing position; When supply voltage is greater than or equal to 85% rated supply voltage, can reliably close a floodgate and remain on the closing position; When the supply voltage falling is following to 35% rated voltage, circuit breaker is separating brake reliably, when under-voltage coil is switched on for a long time simultaneously, temperature rise is no more than the standard gauge definite value, isolating diode 3 is under-voltage power paths, intercepts power switch simultaneously so that under-voltage power supply and power switch can be added in simultaneously is under-voltage, on the closing coil 12 (1), device for under-voltage releasing equipment and permanent magnet mechanism are integrated, and promptly permanent magnet mechanism has added the function of device for under-voltage releasing equipment.
Embodiment 2:
As shown in Figure 2, the utility model has a permanent magnet mechanism housing 5,5 are provided with moving iron core 6, switching winding 9 and the adjustable permanent magnet 2 of piece number in the permanent magnet mechanism housing, 6 times exits of said moving iron core are connected to linkage 7, be connected with adjustable separating brake extension spring 4 and contact compression spring 8 on the said linkage 7, the bottom is provided with under-voltage coil 12 and closing coil 1 in permanent magnet mechanism housing 5, and the exit of under-voltage coil 12 and closing coil 1 is drawn under-voltage power end 11 and power switch end 10 respectively.
By the adjustment of permanent magnet 2 and tripping spring, make circuit breaker in operating temperature range, can remain on closing position.After connecting under-voltage power supply, when supply voltage was lower than 35% rated voltage, circuit breaker can not remain on the closing position; When supply voltage is greater than or equal to 85% rated supply voltage, can reliably close a floodgate and remain on the closing position; When the supply voltage falling is following to 35% rated voltage, circuit breaker is separating brake reliably, and when under-voltage coil was switched on for a long time simultaneously, temperature rise was no more than the standard gauge definite value, device for under-voltage releasing equipment and permanent magnet mechanism are integrated, and promptly permanent magnet mechanism has added the function of device for under-voltage releasing equipment.
