The utility model discloses solve surge protector at the root and when the lightning current, SPD that bear the over specified value broke down the short circuit unusually in practical application, surge protector trip gear unreliable arouses the problem of potential safety hazard, and L type dropout copper sheet has increased the dropout with the mode that dabs the switch and closely laminate and has instructed the degree of accuracy, reduces the erroneous judgement.
Description
Technical Field
The utility model relates to an electronic and electrical equipment's thunder and lightning surge protection technical field especially relates to a many pulse surge protector.
Background
A Surge Protector (SPD) is lightning surge protection equipment of electronic and electrical equipment, is arranged on a line and is one of important measures for preventing lightning current and instant high voltage generated by natural lightning from damaging the electronic and electrical equipment and the line. However, in practical application, explosion and fire accidents still exist in the surge protectors qualified through laboratory tests, and particularly in the primary surge protector applied between the PZ0 and the PZ1, the surge protector installed at the position can resist stronger lightning surge energy. A large amount of data analysis shows that the performance of part of the surge protectors cannot reliably reach the specified through-current capacity, or the actually born lightning current exceeds the specified value, or the SPDs break down the short circuit abnormally, and at the moment, the self-contained tripping devices of the surge protectors cannot trip or cannot trip rapidly, so that safety accidents are caused.
The prior art mostly depends on the mode that the low temperature soldering tin point drops off after reaching certain temperature, utilizes the influence of factors such as low temperature soldering tin thermal trip principle received environment, welding process, often can not drop off according to the accuracy of expectation effect, has very big potential safety hazard. Meanwhile, in the aspect of tripping alarm, a tension spring is mostly installed on a welding copper sheet, and when the copper sheet connected with the lightning protection element and the output end is disconnected, the action of the spring is utilized to touch a nearby switch device to start an alarm function. Actual case analysis finds that sometimes welding points cannot be tripped, sometimes welding copper sheets are directly blown away, the copper sheets cannot touch the switch device, the rear end cannot monitor the damaged condition of the surge protection device, misjudgment is caused, and timely maintenance and measures are not facilitated.
According to research of industry authoritative experts and institutions, the lightning characteristics of the natural world better accord with the continuous discharge characteristics of multiple lightning currents, and the 2PfG 2634/08.17 standard 'additional test-performance requirement and test method of a multi-pulse surge protection device connected to a low-voltage power supply system' which is written by authorities such as the Leishi Ruiv group in Germany and the Reunion in Beijing and the like is added with a multi-pulse test on the basis of the original international standard test, and the test technology is closer to the condition that the surge environment of a distribution side SPD in line transmission is influenced by the physical characteristics of the natural lightning. The above shows that the multi-pulse surge protector is a future research direction in the lightning protection industry.
Compared with the traditional single-pulse technology surge protector, according to the requirements of new standard test standards, the surge energy which needs to be endured by the multi-pulse surge protector is larger and stronger, so that the main circuit can be timely disconnected when the multi-pulse surge protector encounters abnormal conditions in practical application, and higher requirements are provided in the aspects of safety accidents such as explosion, fire and the like.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the potential safety hazard problem that surge protector especially multi-pulse surge protector dropout reliably arouses, provide a novel many pulse surge protector of dropout formula, the utility model discloses can solve traditional dropout and the unreliable unsafe problem of indicating mode.
The technical scheme of the utility model is that:
a novel trip type multi-pulse surge protector comprises a lightning protection element, an L-shaped trip copper sheet, a remote alarm circuit board, a surge protector input end and a surge protector output end, wherein a circular through hole is formed in the L-shaped trip copper sheet and is connected between an electrode of the lightning protection element and the surge protector output end; the remote alarm circuit board is provided with a touch switch and a remote alarm port; the light touch switch is located below the L-shaped tripping copper sheet, an elastic handle of the light touch switch faces upwards, and the light touch switch is in seamless and tight fit with the L-shaped tripping copper sheet.
The beneficial effects of the utility model reside in that: through set up circular through-hole on L type dropout copper sheet, become little through the sectional area, current path narrows down relatively, reaches to restrict the thunder current within the specified value that sets up, when the impulse current that exceeds the specified value flows through surge protector and the power frequency short-circuit current appears, sets up the position of round hole and be the weakest link, causes the copper sheet to break off from setting up the round hole department, has strengthened the dropout reliability when surge protector meets the abnormal conditions, avoids the potential safety hazard. The elastic handle of the tact switch is in seamless close fit with the L-shaped tripping copper sheet, so that once the L-shaped tripping copper sheet is disconnected, the elastic handle of the tact switch loses pressure and rapidly bounces, and a remote alarm port connected with the elastic handle outputs tripping indication information, so that the accuracy of tripping alarm is improved, and misjudgment is reduced. In the production process, the L-shaped tripping copper sheet is simpler and more convenient to process and weld, the production cost is saved, and the production efficiency is improved.

Fig. 1 is a schematic structural diagram of the present invention.
In fig. 1: 1, an L-shaped tripping copper sheet; 2, a light touch switch; 2-1, lightly touching an elastic handle 3 on the switch and lightning protection elements; 4. a remote alarm circuit board; 5. an input end of a surge protector; 6. an output end of the surge protector; 7. a remote alarm port.
Detailed Description
The present invention will be described with reference to fig. 1.
L type dropout copper sheet one end welding is on lightning protection component electrode, the L type dropout copper sheet other end and surge protector's for the output screw fastening, the lightning protection component other end is connected with the surge protector input, when the lightning current or the power frequency short circuit current that exceed the specified value flow through surge protector, the circular through-hole department of L type dropout copper sheet is the weakest link, cause the dropout copper sheet from seting up round hole department disconnection, strengthened the dropout reliability when surge protector meets the abnormal conditions, avoid the potential safety hazard. The elastic handle of the tact switch is located under the hole of the L-shaped tripping copper sheet and is in seamless close fit with the L-shaped tripping copper sheet, once the L-shaped tripping copper sheet is disconnected, the elastic handle of the tact switch loses pressure and rapidly bounces, the remote warning circuit board has the functions of installing and fixing the lightning protection element, inputting and outputting ends, meanwhile, the circuit board is provided with a remote warning circuit, the tact switch and the remote warning port are electrically connected, when the elastic handle of the tact switch acts, the remote warning port outputs tripping information to a client, the accuracy of tripping warning is improved, and misjudgment is reduced.
