Detailed Description
As shown in fig. 1 and fig. 2, the utility model provides an escalator surge protection device, including surge protection device 1 and trouble display box 2, the surge protection device has modular composite structure, including voltage limiting unit and electrical interface 4, is used for limiting thunder overvoltage or operation overvoltage; the surge protection device 1 is parallelly connected to the electric wire netting with the user incoming end of staircase equipment, the surge protection device passes through electrical interface 4 is connected with main control unit 3 of staircase, the long-range dry junction feedback of surge protection device output is to main control unit 3, main control unit 3 with fault display box 2 is connected. The remote output dry contact of surge protection device is the manufacturer design and manufacture of surge protection device to reserve electrical interface 4 and use for staircase designer, the staircase designer only needs simple electrical connection can accomplish, and its theory of operation is: once the surge protection device detects the lightning overvoltage or the operation overvoltage, the reserved electrical interface 4 is normally closed and becomes normally open and feeds back an electrical signal to the main controller 3, and at the moment, the situation that the main controller 3 detects the lightning overvoltage or the operation overvoltage is the same.
The surge protection device is preferably an SDZ-20 series, the SDZ-20 series is a surge protection device with a modular combination function, can protect against induction thunder, is a parallel protection device, is widely applied to secondary and tertiary overvoltage protection of various power systems, and is mainly used in floors of building power supply systems or indoor distribution boxes, low-voltage switch cabinets and distribution cabinets. When the power grid system is normal, the voltage limiting device in the SDZ-20 series products is in a high-resistance state, and the display window is green at the moment; when lightning overvoltage or operation overvoltage occurs in the circuit, the voltage limiting device responds at nanosecond speed to present a low-resistance state and limit the amplitude of the overvoltage to a lower level, so that the equipment is protected from being damaged by the overvoltage. In addition, when the surge protection device detects that the electric equipment is abnormal, the remote dry contact can be output and fed back to the main controller, the relevant faults of the fault display box are informed, the reference is made to the pre-diagnosis of escalator maintenance personnel, and the damaged surge protection device and the damaged module are replaced.
In addition, the surge protection device 1 further includes a thermal fuse and a current fuse, so that the surge protection device is safely separated from a power supply line after being degraded. And the safety of a rear-stage electrical system is ensured.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and changes will readily occur to those skilled in the art based upon the teachings of the present invention. Therefore, the technical solutions that can be obtained by logic analysis, reasoning or limited experiments based on the prior art according to the design concept of the present invention should be within the scope of the present invention and/or the protection scope defined by the claims.
