Embodiment Construction

[0016] The present invention will be further elaborated below with reference to the accompanying drawings.

[0017] see figure 1 A signal lightning protector provided by the present invention includes an interface CON2, the interface CON2 has a remote signal input terminal J1 and a remote signal output terminal J2, and is used for the signal lightning protector to output a remote signal signal. The interface CON2 can be any one of RJ45 interface, RS485 interface, RS232 interface or DB09 interface, and can also be connected in series with the remote signaling interface with thermal tripping principle to realize function expansion.

[0018] The signal lightning protector also includes an induction coil L2 and an alarm circuit, and the induction coil L2 may be a ring-shaped current induction coil. One end of the induction coil L2 is connected to the remote signal input terminal J1, the other end is connected to one end of the alarm circuit, and the other end of the alarm circuit...

Abstract

The invention relates to a signal lightning protection device. The signal lightning protection device comprises an interface. The interface is provided with a remote signaling input end and a remote signaling output end. The device further comprises a sensing coil and an alarm circuit. One end of the sensing coil is connected with the remote signaling input end, and the other end of the sensing coil is connected with one end of the alarm circuit. The other end of the alarm circuit is connected with the remote signaling output end. The alarm circuit comprises a first circuit and a second circuit connected in parallel with the first circuit. At a normal working state, the first circuit is switched on and the second circuit is switched off. At a degradation state, the first circuit is switched off and the second circuit is at a high-impedance state. According to the invention, through arrangement of the alarm circuit, a remote signaling degradation real-time alarm function is realized, the wiring is simple, power supply by use of a power source is unnecessary, the safety and the reliability are improved, the volume is small, and the structural compatibility is good.

Description

technical field [0001] The invention relates to the technical field of lightning protection equipment, in particular to a signal lightning protection device with a remote signal degradation real-time alarm function. Background technique [0002] At present, the signal surge protectors on the market generally use the principle of thermal tripping to realize the real-time alarm function of remote signal degradation, that is, the degraded surge protector achieves the purpose of warning by fusing the thermal fuse after heating. However, the alarm effect of this method is relatively poor, because in most cases, the heat emitted by the gas discharge tube and transient diode used on the signal lightning arrester is very low after deterioration, which is often not enough to blow the thermal fuse, resulting in Misjudgment by the maintenance personnel of the signal lightning arrester. Contents of the invention [0003] The purpose of the present invention is to provide a signal lig...
