Abstract

The invention discloses an uninterruptible power supply maintaining bypass device. A first breaker, a second breaker and a third breaker can be three single-pole breakers, or the first breaker is a single-pole breaker, the second breaker and the third breaker are a first switch circuit and a second switch circuit of a double-pole breaker, the using numbers of double-pole breakers is reduced, and accordingly maintaining bypass cost is lowered. Through a hot-pluggable connector, the hot-plug function of the uninterruptible power supply maintaining bypass device and an uninterruptible power supply is achieved, and accordingly on-line maintaining can be carried out on the uninterruptible power supply. The using number of the double-pole breakers is reduced, so that a maintaining bypass is small in occupied space and can be easily integrated into a UPS machine case, and accordingly machine frame space is saved.

Description

technical field [0001] The invention relates to the technical field of electric power systems, and more specifically, relates to an uninterruptible power supply maintenance bypass device and an uninterruptible power supply system. Background technique [0002] Uninterruptible Power System (UPS) is an important external device that can provide continuous, stable and uninterrupted power supply for the load. Since the UPS needs to be powered off when replacing or maintaining the UPS, but it is necessary to ensure that the load connected to the UPS is not powered on, so in order to ensure that the load is not powered on when the UPS is replaced or maintained, it is necessary to equip the UPS with a maintenance bypass components. [0003] A commonly used way to implement the maintenance bypass at present is to configure a maintenance bypass cabinet outside the UPS. The structure of the maintenance bypass cabinet and the connection relationship between the maintenance bypass cab...
