Title:
POWER SUPPLY METHOD FOR ELEVATOR CAR STORAGE BATTERY
Document Type and Number:
WIPO Patent Application WO/2017/124796
Kind Code:
A1
Abstract:
A power supply method for an elevator car storage battery (1). According to the power supply method, a storage battery (1), au auxiliary charging apparatus (2), an inversion power supply apparatus (3), a three-phase transformer (4), a power conversion apparatus (5), and an elevator car power utilization load (6) are comprised; the output end of the auxiliary charging apparatus (2) is connected to the input end of the storage battery (1); the output end of the storage battery (1) is connected to the input end of the inversion power supply apparatus (3); the inversion power supply apparatus (3) is connected to the primary side of the three-phase transformer (4) by means of a first micro circuit breaker (7); the secondary side of the three-phase transformer (4) is connected to the input end of the power conversion apparatus (5) by means of a rectifying module (8); and the output end of the power conversion apparatus (5) is connected to the elevator car power utilization load (6) by means of a second micro circuit breaker (9). In the technical solution, the structure and the principle are simple, and power is saved; a used power-off detection module (10) can detect the power supply condition of the storage battery (1) in real time; and meanwhile, the second micro circuit breaker (9) is connected between the power conversion apparatus (5) and the elevator car power utilization load (6), so that the load can be protected, and the service life of the load can be prolonged.
