Abstract
This utility model discloses a PC stage dual supply automatic switchover switch, comprising a housing and a protective frame which is clamped in the housing. The protective frame is in one piece, and consists of a support plate, four long inserting plates and a short inserting plate. The four long inserting plates and the short inserting plate are arranged under the support plate. The PC stage dual supply automatic switchover switch has an attractive appearance and safe usage.
Description
Technical field
The utility model relates to a kind of double power supply automatic switching switch, refers in particular to a kind of PC level double power supply automatic switching switch.
background technology
Duplicate supply refers to: a kind ofly by microprocessor, controlled, for network system net electricity and net electricity or net electricity, start with generator power supply the device switching, can make the power supply of power supply continuous source.When conventional electric catastrophic failure or while having a power failure, by double power supply converting switch, automatically put on stand-by power supply, (under little load, stand-by power supply also can be by generator powered) still can normally move equipment.Modal is for elevator, fire-fighting, monitoring.Duplicate supply is mainly divided into PC level duplicate supply (integral type) and CB level duplicate supply (dual-breaker formula).PC level duplicate supply: can connect, carry but be not used in the duplicate supply of disjunction short circuit current.If duplicate supply selects the on-load switch without overcurrent trip to belong to PC level automatic change-over as actuator.Do not possess defencive function, but it possesses higher tolerance and making capacity, can guarantee the safety of switch self, not because the faults such as overload or short circuit are damaged, guarantee in the case to connect reliably loop.At present, not only there is use potential safety hazard in commercially available PC level double power supply automatic switching switch, and profile is not attractive in appearance.
summary of the invention
The purpose of this utility model is to provide a kind of PC level double power supply automatic switching switch, and its good looking appearance is used safety.
For achieving the above object, solution of the present utility model is: a kind of PC level double power supply automatic switching switch, it comprises shell, protective frame snaps in shell, this protective frame is integrated, by a support plate, four long plates and a short plate, formed, four long plates and a short plate are set under support plate.
The shell of existing PC level double power supply automatic switching switch is not with protective frame, and profile is neither attractive in appearance, unshielded between its binding post, if security incident easily occurs bad spark of certain termination contact.The utility model is set up protective frame, reaches good looking appearance, uses safe object.
