Problems solved by technology

It can be seen from this that if the value of R3 cannot be well controlled, then the voltage value U at both ends of the surge protector cannot be reduced when it is struck by lightning, and when the surge protector is struck by lightning, if the maximum voltage of the device is satisfied, it should be greater than the voltage value U, can protect the equipment well, otherwise, the equipment will be damaged when the voltage is too large

specific Embodiment 1

[0042] like Figure 1-Figure 9 As shown, in this embodiment, a surge protector capable of resisting high-intensity lightning current is specifically provided, including an SPD case 1, a first output electrode 10 and a second output electrode 10 arranged on both sides of the SPD case 1 and parallel to each other. Electrodes 2, wherein, the SPD case 1 is used as the carrier of various components inside the surge protector, and the first output electrode 10 and the second output electrode 2 are embedded in the inside of the SPD case 1, and the first output electrode 10 Connected in the circuit loop of the protected equipment, while the second output electrode 2 is grounded.

[0043] An assembly space is formed between the first output electrode 10 and the second output electrode 2, and the trip assembly and the piezoresistor unit 11 are arranged along the same plane in the assembly space, such as Image 6 , Figure 7 As shown, the tripping assembly and the piezoresistor unit 11...

specific Embodiment 2

[0050] In order to further improve the ability of the surge protector to quickly isolate the current arc when there is an overcurrent inside, the following structure is designed on the basis of the specific embodiment 1:

[0051] The tripping assembly also includes an arc shielding mechanism. The working principle of the arc shielding mechanism is: when the tripping bracket 4 generates a disengagement movement, the limiting effect of the tripping welding piece 5 on the arc shielding mechanism is eliminated, and the arc shielding mechanism then Carry out linkage movement and isolate the tripping welding piece 5 and the thermal tripping electrode 6, so as to prevent an arc between the tripping welding piece 5 and the thermal tripping electrode 6 when an overcurrent flows inside the surge protector sparks to avoid safety accidents.

[0052] The arc shielding mechanism includes an arc shielding plate 8 slidably arranged on the trip bracket 4, the arc shielding plate 8 is equipped ...

specific Embodiment 3

[0054] In order to further improve the real-time display of the working status of the surge protector during use, the following structure is designed on the basis of the second embodiment:

[0055] It also includes a tripping display component, the display state switching of the tripping display component is driven by the tripping movement of the tripping component, that is, when the tripping component performs a tripping action, it can cause the tripping display component to produce a linkage movement, To remind the user of the usage status of the surge protector in time.

[0056] The tripping display assembly includes a display window 20 located at the top of the SPD shell 1, and the display window 20 is used to display the current working state of the surge protector to warn staff whether the surge protector is in a damaged state, Whether it needs to be replaced or repaired in time.

[0057] The tripping display assembly also includes a top frame 9 and an indicator plate m...

Abstract

The invention discloses a surge protector capable of resisting a high-intensity lightning current. The surge protector belongs to the technical field of surge protectors, and comprises an SPD outer shell, and a first output electrode and a second output electrode arranged on two sides of the SPD outer shell and parallel to each other. An assembly cavity is formed between the first output electrodeand the second output electrode, a tripping assembly and a piezoresistor unit are arranged in the assembly space along the same plane, and the tripping assembly is positioned below the piezoresistorunit; and the first output electrode, the piezoresistor unit, the tripping assembly and the second output electrode are sequentially connected in series to form a conductive path, and the conductive path is disconnected under a tripping action of the tripping assembly, thereby achieving the effect of greatly reducing resistance inside the surge protector, and realizing the purposes of effectivelycontrolling voltage to protect equipment under the action of the high-intensity lightning current.

Description

technical field [0001] The invention belongs to the technical field of surge protectors, and in particular relates to a surge protector capable of resisting high-intensity lightning current. Background technique [0002] Surge protector, also called lightning protector, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When a peak current or voltage suddenly occurs in the electrical circuit or communication line due to external interference, the surge protector can turn on the shunt in a very short time, thereby avoiding damage to other equipment in the circuit by the surge. [0003] Surge protector, suitable for AC 50 / 60HZ, rated voltage 220V to 380V power supply system, to protect against indirect lightning and direct lightning effects or other transient overvoltage surges, suitable for family residences, tertiary industries and industries field surge protection requirements. When a peak curren...
