Abstract
A kind of network electric power combined arrester, is made up of network protection module and power source protective module two parts; Network protection module is made up of network interface input, lightning protection module for network and network interface output; Power source protective module by power input, lightning protection module of power source, voltage detecting circuit, unshakable in one's determination group, electronic switch module, voltage comparator circuit, relay module and power output end form.This network electric power combined arrester not only has the function of network ' s thunder and power lightning protection, but also has possessed the protection of voltage overvoltage/undervoltage and earth leakage protective function, the safe operation of omnibearing protection power consumption equipment.When being struck by lightning, lightning current of can effectively releasing, protection power consumption equipment; When there is electric voltage exception or electric leakage, automatically can cut off out-put supply, protection power consumption equipment safety, when voltage resume normal value, again can automatic closing.Eliminate the cost of labor that power consumption equipment is safeguarded in a large amount of artificial inspections.
Description
Technical field
The utility model, as a kind of network electric power combined arrester, is particularly useful for the camera monitoring system of road, can carry out lightning protection, and carry out overvoltage/undervoltage protection and earth leakage protective to power supply to the power supply of supervisory control system and network signal.
Background technology
At present, along with road is constantly fast-developing, the particularly universal development of highway, vehicle also increases thereupon.Each is important, flow of the people is large, road camera monitoring system all can be installed in the crossing of Frequent Accidents and traffic lights.Conveniently traffic administration and social security management, the installation of road camera also gets more and more, and increasing extent is large.And road camera head monitor is nearly all mounted in outdoor, being struck by lightning than being easier to, safeguarding and relatively bothering.And owing to being in outdoor, camera monitoring system voltage fluctuation is comparatively large, and long-term overvoltage or under-voltage operation, can bring damage to camera.Also single power lightning protection or the product of network ' s thunder is had on the market; and single overvoltage-undervoltage protector and leakage switch; these are all the protective devices that road camera needs to install; but the inside installing space of camera brandreth is limited; if install cumbersome one by one, and cost compare is high.
Utility model content
The purpose of this utility model is a kind of network electric power combined arrester of development; not only there is the function of network ' s thunder; also there is the function of power lightning protection; also possessed the overvoltage/undervoltage protection of power supply and earth leakage protective function simultaneously; when input power fluctuation ratio is larger or when there is leaky; the output circuit of circuit meeting automatic cut-off power, protection power consumption equipment.When voltage resume is normal, again can automatic closing, while protection power consumption equipment fast, the personnel of eliminating patrol and safeguard great amount of cost.
The utility model solves the technical scheme that its technical problem adopts:
A kind of network electric power combined arrester, is made up of network protection module and power source protective module two parts; Network protection module is made up of network interface input, lightning protection module for network and network interface output; Power source protective module by power input, lightning protection module of power source, voltage detecting circuit, unshakable in one's determination group, electronic switch module, voltage comparator circuit, relay module and power output end form.Network interface input is connected with lightning protection module for network, and lightning protection module for network is connected with lightning protection module of power source, network interface output; Power input is connected with lightning protection module of power source, and lightning protection module of power source is organized with iron core and is connected; Group unshakable in one's determination is connected with voltage detecting circuit, electronic switch module and relay module; Relay module is connected with power output end.
Network protection module is mainly undertaken lightning protected by lightning protection module for network.
Power source protective module completes lightning protected primarily of lightning protection module of power source; simultaneously; by the magnitude of voltage above Real-Time Monitoring circuit; when the magnitude of voltage on incoming line exceeds the valid value range of setting; voltage comparator circuit just can pass through Control outlet line, allows power consumption equipment from damage.When circuit occurs leaky, by unshakable in one's determination group, the imbalance of inspection vehicle incoming line and outlet line voltage, allows electronic switching circuit control relay disconnect outlet line.When circuit all recovers normal, testing circuit detects normal signal, is just automatically closed by lock.
The utility model is as a kind of network electric power combined arrester; not only there is the function of network ' s thunder; also there is the function of power lightning protection; also possessed the overvoltage/undervoltage protection of power supply and earth leakage protective function simultaneously; when input power fluctuation ratio is larger or when there is leaky; the output circuit of circuit meeting automatic cut-off power, protection power consumption equipment.When voltage resume is normal, again can automatic closing, while protection power consumption equipment fast, the personnel of eliminating patrol and safeguard great amount of cost.And total adopts integration apparatus, space requirement is little, facilitates site operation to install.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart.
