The surge protector with dry contact output claimed by the present invention will be further described in detail with reference to the following embodiments. Fig. 1 is a schematic diagram showing a partial structure of a surge protector with dry contact output according to an embodiment of the present invention; fig. 2 is a partial schematic structural diagram of a normal surge protector with dry contact output according to an embodiment of the present invention; fig. 3 is a partial schematic structural diagram showing a fault of a surge protector with dry contact output according to an embodiment of the present invention; and fig. 4 shows a schematic structural diagram of a surge protector with dry contact output according to an embodiment of the present invention.
As shown in fig. 1 to 4, the present invention discloses a surge protector with dry contact output, comprising: the lightning protection device comprises a base 1, a lightning discharge assembly 2, a remote signaling assembly 3 and a base cover 4. The base cover 4 is buckled outside the base 1; the lightning discharge assembly 2 comprises at least one electrode conductive electrode shrapnel 201; a lightning protection element 202, a grounding conductive bar 203; the remote signaling assembly 3 comprises micro switches 301, a PCB 302, signal lines 303, output terminals 304 and bolts 305, wherein the number of the micro switches corresponds to that of the conductive electrode shrapnel 201; one end of each conductive electrode elastic sheet 201 is correspondingly pressed on one microswitch 301, and the other end of each conductive electrode elastic sheet 201 is connected to the lightning protection element 202; the lightning protection element 202 is connected to the grounding conductive bar 203; the microswitch 301 is plugged on the PCB 302; the PCB 302 is fixed in the base 1 by the bolt 305, and the PCB 302 is connected to the output terminal 304 by the signal line 303; the lightning discharging assembly 2 and the remote signaling assembly 3 are integrally arranged in the base 1.
Specifically, the lightning discharging assembly 2 includes at least one conductive electrode spring 201; a lightning protection element 202, a grounding conductive bar 203; and placing the conductive electrode elastic sheet 201 of each electrode into the corresponding position of the base 1, and welding one end of the conductive electrode elastic sheet 201 and one end of the lightning protection element 202 by using low-temperature solder. The lightning protection element 202 is characterized as being in a high-impedance state in a normal state, but when there is a lightning strike or an overvoltage, the resistance value of the lightning protection element 202 is instantly reduced to be very small, which is equivalent to a short-circuit state. At this time, the surge current passes through the conductive electrode spring 201, the lightning protection element 202 and the grounding conductive bar 203 in sequence, and finally is discharged to the ground, so that the electric equipment is protected from being damaged by lightning.
As shown in fig. 2, when the surge protector is normal, the conductive electrode elastic sheet 201 is pressed above the corresponding microswitch 301, and the microswitch 301 is in a closed state; as shown in fig. 3, when the surge protector fails, the conductive electrode elastic sheet 201 is bounced, and the corresponding micro switch 301 changes from a closed state to an open state. When the surge protector is damaged, the output terminal 304 remotely signals an alarm signal of the dry contact property for alarming whether the operation state of the surge protector is damaged.
In the actual use process, as shown in fig. 2, when the surge protection device is normal, the conductive electrode elastic sheet 201 presses the micro switch 301, so that the micro switch 301 is in a closed state, and at this time, the micro switch is in a compressed state. When the surge protector is in good condition all the time, the state of the microswitch will remain normally closed all the time. As shown in fig. 3, when the surge protector fails due to a lightning strike or an overvoltage, the low-temperature solder between the conductive electrode dome 201 and the lightning protection element 202 melts, so that the conductive electrode dome 201 is separated from the lightning protection element 202 under the action of its own elastic force, and the swing rod of the microswitch 301 which is pressed at this time is also bounced. The state of the microswitch 301 is changed from closed to open. This signal is finally output to the monitoring device through the output terminal 304. I.e. feedback and monitoring of the state of the surge protector is achieved.
Preferably, the lightning discharging assembly 2 is arranged at the side of the base 1; the remote signalling assembly 3 is fixed to the base 1 at the bottom by bolts 305. When assembling, firstly, the lightning discharging assembly 2 is installed in a corresponding groove of the base 1, and secondly, the remote signaling assembly 3 is placed on a corresponding position of the base 1. The PCB board 302 is then fixed to the base 1 by bolts 305. The output terminals 304 are readjusted and assembled. Finally, the base cover 4 is buckled, and the whole assembly can be completed.
The utility model can effectively assemble all functions in the base in a centralized way, greatly facilitates production and assembly, and simultaneously carries out modularized design and connection, thereby greatly improving the assembly convenience and further improving the production efficiency.
Preferably, the conductive electrode dome 201 and the lightning protection element 202 are welded by low-temperature solder. When the surge protector fails due to lightning or overvoltage, the low-temperature solder between the conductive electrode elastic sheet 201 and the lightning protection element 202 is melted, so that the conductive electrode elastic sheet 201 is separated from the lightning protection element 202 under the action of the elastic force of the conductive electrode elastic sheet, and the swing rod of the extruded microswitch 301 is also bounced. The state of the microswitch 301 is changed from closed to open.
Preferably, the base cover 4 is convex, and a limit hole is formed in the side surface of the base cover 4; the output terminal 304 is fixed at the position-limiting hole so as to output signals to the outside.
Preferably, the periphery of the bottom of the base 1 is provided with a fixing buckle, and the periphery of the bottom of the base cover 4 is provided with a fixing clamping groove; the fixed clamping groove is clamped with the fixed buckle so that the base cover 4 is matched with the base 1 in an assembling mode.
Preferably, a monitoring device is further included, the monitoring device being in signal connection with the output terminal 304. Finally, the signal of the state change of the microswitch 301 is output to a monitoring device through the output terminal 304. I.e. feedback and monitoring of the state of the surge protector is achieved.
Compared with the prior art, the surge protector with the dry contact output of the embodiment of the utility model has the following beneficial effects:
