Abstract
The utility model discloses a surge protector circuit of a low-voltage power supply and relates to the technical field of protection circuits. The surge protector circuit comprises redundancy backup circuits which are parallelly connected, wherein the redundancy backup circuits are laterally connected with a telecommand alarm device. The redundancy backup circuits include a pulse discharging circuit, a follow current limiting protection device, an impact peak value monitoring device and a surge recognition device, wherein the follow current limiting protection device, the surge recognition device and the pulse discharging circuit are sequentially connected and then laterally connected with the impact peak monitoring device. The surge protection circuit is reasonable in design, can discharge pulse overvoltage motions generated in real time by electrical equipment or power distribution rooms which are already put into use so as to achieve the aim of protection and further can check operation performance of a protector and an arrester counter. The response speed of the impact peak value monitoring device is 5nS, reaction speed of the protector is greatly improved, and a leakage channel is limited.
Description
Technical field:
The utility model relates to the protective circuit technical field, relates in particular to a kind of HLSP type low-tension supply Surge Protector circuit.
Background technology:
In view of there are some destabilizing factors in power circuit, and design is used for preventing that the loop that this type of destabilizing factor influences the circuit effect is called protective circuit.Such as overcurrent protection, overvoltage protection, overtemperature protection, no-load protection, short-circuit protection etc. are arranged.
In the electrical energy production and consume system be made up of links such as generating, transmission of electricity, power transformation, distribution and electricity consumptions, electric equipment is indispensable.
At present, because the structure defectiveness of electric equipment, installation quality is not good, fault, and the accident proportion that thunder and lightning and static cause is very big.Therefore, in order to ensure the person and device security, the protective device of lightning protection, anti-overvoltage and overcurrent should be installed all in the power distribution room.In the prior art, be used to protect the protective device of electric equipment and Circuits System, function ratio is more single, and reaction speed is sensitive inadequately, and security performance can not satisfy the needs of the electric and Circuits System of present protection.
The utility model content:
The utility model technical problem to be solved is to overcome the defective of prior art, the HLSP type low-tension supply Surge Protector circuit that provide a kind of and be quick on the draw, security performance is high.
The utility model technical problem to be solved adopts following technical scheme to realize.
A kind of low-tension supply Surge Protector circuit; It is characterized in that: this circuit comprises the redundant backup circuit of parallel connection; The other remote signalling alarm device that connects of redundant backup circuit; Said redundant backup circuit comprises pulse leadage circuit, afterflow limiting protector, impact peak value monitoring device and surge recognition device, after said afterflow limiting protector, surge recognition device and pulse leadage circuit are connected successively, and the other again impact peak value monitoring device that connects.
The utility model is reasonable in design, can release to the electrical appliance or the real-time pulse surge action that produces of power distribution room of having come into operation, to reach the protection purpose, also can check the runnability of protector and lightning arrester counter.The reaction speed of impact peak value monitoring device is 5nS, has greatly improved the reaction speed of protector and has limited leak channel.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1; A kind of low-tension supply Surge Protector circuit; This circuit comprises the redundant backup circuit 2 of parallel connection, and redundant backup circuit 2 sides connect remote signalling alarm device 1, and redundant backup circuit 2 comprises pulse leadage circuit 24, afterflow limiting protector 21, impact peak value monitoring device 23 and surge recognition device 22; After said afterflow limiting protector 21, surge recognition device 22 and pulse leadage circuit 24 are connected successively, the other again impact peak value monitoring device 23 that connects.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
