Description

Technical Field

[0001] The utility model relates to a surge protector, in particular to a surge protector with backup switch protection. Background Art

[0002] Surge protector, also known as lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instruments and meters, and communication lines. When a sudden peak current or voltage is generated in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt the current in a very short time, thereby preventing the surge from damaging other equipment in the circuit. Surge protectors are generally suitable for use in AC 50 / 60HZ, rated voltage 220V / 380V power supply systems to provide protection against indirect lightning and direct lightning effects or other transient overvoltage surges. They are widely used in residential, tertiary and industrial applications requiring surge protection. Existing surge protectors lack backup switch protection, which can easily lead to damage to the protected lines or products due to lack of protection during the safety protection process.

The utility model solves the problem that the stability of the existing surge protector needs to be improved by providing a slide rail body, a surge protector body, a moving rod, a movable groove, a connecting rod, a plug rod, a round block, a support plate, a spring, a clamping groove, a fixing plate, an outlet and a push rod. When the surge protector is in use, it is generally slidably limited on the surface of the slide rail for fixed use. The slide rail can only limit the surge protector and cannot effectively ensure that the surge protector is stably placed on the surface of the slide rail, thereby reducing the stability of the surge protector. This solution also has the problem of not having a backup switch protection function, which may cause damage to the protected lines or products due to lack of protection during the safety protection process.

The electrical connection is simultaneously connected to the A connection point of the left reserve protection zone 10; the JX-2 terminal of the unidirectional gap JX of the left reserve protection zone 10, the FDG-2 terminal of the gas discharge tube FDG and the DCX-2 terminal of the electromagnetic coil DCX are electrically connected in parallel and electrically connected to the B connection point of the left reserve protection zone 10; the B connection point of the right surge discharge zone 20 is electrically connected to the SM-1 terminal of the T1 graphite multi-level discharge gap assembly SM, the SM-2 terminal of the T1 graphite multi-level discharge gap assembly SM is electrically connected to the C connection point of the right surge discharge zone 20, and the C connection point of the right surge discharge zone is electrically connected to the grounding terminal of the left reserve protection zone 10; the tripping and resetting of the backup switch drives the remote signaling switch to output a prompt signal.

[0015] The C connection point of the right surge relief zone 20 is electrically connected to the C connection point of the left backup protection zone 10 .

[0016] The three components of the electromagnetic coil DCX, the gas discharge tube FDG and the unidirectional gap JX together constitute a step-by-step increasing through-current backup protector.

[0017] An arc extinguishing cover 14 and a self-locking mechanism 13 are installed and connected on the left reserve protection zone 10, and a fault trip linkage indicator 21, a first linkage spring 22, a second linkage spring 24, a compression spring 23, and a C connection point connected to the soft wire CR and the temperature overtemperature monitoring point 25. The spring end of the first linkage spring 22 is in contact with the temperature overtemperature monitoring point 25. The temperature overtemperature monitoring point 25 is connected to a protrusion at one end corner of the T1 switch type graphite multi-stage discharge gap assembly SM, and a B connection point is installed and connected at the protrusion at the other end corner of the T1 switch type graphite multi-stage discharge gap assembly SM.

[0018] When in use, the T1 switch type surge protector is connected in the following way:

[0019] The KG-1 static contact is first introduced through the incoming line terminal of the left backup protector zone, and the moving contact from the KG-2 terminal is connected to point A. The two ends of the DCX, FDG, and JX components are connected in parallel to points A and B, respectively. Point B is then connected to point B of the right surge relief zone, while the two ends of the SM component in the right surge relief zone are connected to points B and C, respectively. Point C is connected to the ground terminal of the left backup protector zone. This establishes a protective electrical connection between the backup switch in the left backup protection zone and the T1 switch-type graphite multi-stage discharge gap component in the right surge relief zone and the remote signaling switch. Tripping and resetting the backup switch triggers the remote signaling switch to output a prompt signal.

[0020] Working principle of T1 switch type surge protector:

[0021] The KG-1 static contact is first introduced through the incoming line end of the left backup protector area, the KG backup switch is closed, and then the moving contact from the KG-2 end is connected to point A. In order to improve the stability of the backup protector, the present invention adopts a step-by-step increasing current design composed of three components: DCX, FDG, and JX. In the state without lightning surge, the Un voltage passes from DCX to point B. When the lightning surge energy reaches a certain level, the FDG is first instantaneously started and turned on to point B. As the lightning surge increases again, the JX component is started and turned on to point B. When the SM component in the surge discharge area on the right detects that point B is in a state of high voltage and high current of lightning surge, the SM component is instantaneously started to discharge the high current of lightning surge high voltage and high current to the ground end in a switching type. Therefore, in order to comprehensively improve the protection performance of the surge protector, the present invention designs a surge protector with switching type protection.

[0022] Working principle of fault protection and remote signaling output of T1 switch type surge protector:

[0023] Power frequency continuous current overcurrent protection: When the SM component in the right surge discharge area short-circuits due to a fault, resulting in power frequency continuous current overcurrent and affecting the operation of the main line, in order not to affect the normal operation of the main line, the surge protector needs to be disconnected from the main line. The present invention instantly starts the linked self-locking mechanism of the DCX component in the left backup protection zone, causing the KG component to disconnect the SM component in the right surge discharge area and continue to work abnormally, and drives YX (telesignaling switch) to operate and send out a telesignaling output prompt signal.

[0024] 2. SM component over-temperature protection: When the SM component in the right surge discharge area overheats, the low-temperature solder at the T1 temperature over-temperature detection point melts, disconnecting the linkage spring 1. Due to the action of the compression spring, the indicator is pushed, and the separation of the indicator causes a red display in the right surge discharge area window, which then drives the linkage spring 2, which in turn drives the self-locking mechanism, causing the KG component to operate and drive the YX (remote signal switch) to operate and send a remote signal output prompt signal.
