Description
Technical field
The utility model relates to the integrated dividing potential drop Surge Protector of a kind of terminal power supply.
Background technology
Along with the continuous progress of science and technology, the extensive use of artificial intelligence and automation equipment, various application class electronic equipments are also universal on a large scale; These equipment consist of one or more integrated circuits, resistance to surge impact capacity very a little less than, the equipment loss causing due to surge is in rising trend year by year, this just has higher requirement to surge protector.
For the surge protection device (spd) of terminal power-supply device, there are at present the lightning protection device of the less protection magnitude of use, earth leakage protector, voltage regulation filtering switchgear and front end fuse protector etc.The protection of these equipment main purposes or restriction surge energy conduction infringement wiring rear end circuit or equipment, rely on the de-mode such as disconnected of ground connection electric discharge, limiting voltage, over-voltage and over-current to protect.What have can repeatedly use, as lightning protection device, and voltage regulation filtering switch; Some needs are frequently changed the one-time action of guard member, as front end fuse protector.In general, no matter be ground connection guiding or hinder restriction surge energy, once all cannot avoid protection equipment failure, or protected equipment is placed under powerful surge energy, or causes protected being run out of steam to drive and quit work.
Utility model content
In view of the above-mentioned problems in the prior art, main purpose of the present utility model is to address the deficiencies of the prior art, and the utility model provides the terminal power supply that a kind of wiring is reliable and security performance is high integrated dividing potential drop Surge Protector.
The utility model provides a kind of terminal power supply integrated dividing potential drop Surge Protector, comprise housing, in described housing, be provided with surge protection circuit, described surge protection circuit comprises the bleeder circuit of a plurality of parallel connections, on each bleeder circuit, be provided with the de-disconnected device of withstand voltage element and protection, also comprise the earthed circuit being connected with the de-disconnected device of described protection, on described earthed circuit, be provided with multichannel protective circuit parallel with one another, in described protective circuit, be provided with protection component, described housing upper surface is provided with working station indicator, one side of described housing is provided with a plurality of power supply lead wires, the upper surface of described housing is also provided with peep-hole.
Optionally, described a plurality of power supply lead wire is two power supply lead wires.
Optionally, the bleeder circuit of described a plurality of parallel connections is two bleeder circuits in parallel.
The utlity model has following advantage and beneficial effect:
1, Integrated design technology, installs and uses necessary electrical wiring by protector and protector Integrated design is machined in one, in product design processing, installation lead-in wire is assemblied among protective circuit;
2, integrated dividing potential drop, multichannel shunting; Improve the barrier propterty of protector, farthest restriction discharges surge energy, can not cause the problems such as size, profile and volume size because of self product simultaneously, and that brings uses and apply inconvenient problem;
3, in face of the powerful surge energy over protector protection specification, the effect of protector maximum likelihood performance ground protection; After surge energy surpasses protector load, infringement protection, can not damage because of the lasting conduction of surge energy the protected equipment in rear end yet.
Accompanying drawing explanation
Fig. 1 is the structural representation of the integrated dividing potential drop Surge Protector of terminal power supply of the utility model embodiment;
Fig. 2 is the schematic diagram of the integrated dividing potential drop Surge Protector of terminal power supply of the utility model embodiment.
Embodiment
With specific embodiment, the utility model is further described below with reference to accompanying drawings.
As depicted in figs. 1 and 2: the integrated dividing potential drop Surge Protector of a kind of terminal power supply of the utility model embodiment, comprise housing 1, in described housing 1, be provided with surge protection circuit, described surge protection circuit comprises the bleeder circuit 4 of a plurality of parallel connections, on each bleeder circuit 4, be provided with the de-disconnected device 6 of withstand voltage element 5 and protection, also comprise the earthed circuit 7 being connected with the de-disconnected device 6 of described protection, on described earthed circuit 7, be provided with multichannel protective circuit 71 parallel with one another, in described protective circuit 71, be provided with protection component 711, described housing upper surface is provided with working station indicator 2, one side of described housing 1 is provided with a plurality of power supply lead wires 3, the upper surface of described housing is also provided with peep-hole 11, this structure can be farthest terminal power supply dividing potential drop, reliability and the security performance of terminal power work have been improved, and then improved the barrier propterty of this protector, also be provided with earthed circuit simultaneously, further improved the fail safe of this protector.
As the preferred implementation of above-described embodiment, described a plurality of power supply lead wires are two power supply lead wires.
As the preferred implementation of above-described embodiment, the bleeder circuit of described a plurality of parallel connections is two bleeder circuits in parallel.
Finally it should be noted that: above-described each embodiment, only for the technical solution of the utility model is described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record previous embodiment is modified, or to wherein partly or entirely technical characterictic be equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
