Abstract
The invention relates to a novel surge protection device. The novel surge protection device mainly comprises a current sensor, a relay, a current blocker, a linkage mechanism, a lightning protection element and a breaking switch. The lightning protection element is connected with the breaking switch in series, the current blocker works in cooperation with the current sensor and the relay, the breaking switch is controlled through a bypass, lightning surges can be discharged normally, power frequency currents of more than 3A can be switched off, and the novel surge protection device is safe and reliable. The novel surge protection device is convenient to mount, the dead zone of an existing SPD overcurrent protection mode is avoided, and high reliability is achieved.
Description
Technical field
The invention belongs to the surge protection technical field of electronic electric equipment.
Background technology
Thunder and lightning is by the charged cloud a kind of special weather phenomenon causing of aloft discharging.Thunder and lightning is the major reason that causes electronic equipment to damage, and it threatens the safe and stable operation of the every field electronic informations such as building, railway, civil aviaton, communication, industry control, military affairs.On the metallic circuits such as the power line being connected with electronic equipment, holding wire and control line, surge protector (SPD) being installed is one of important measures of lightning protection.Surge protector has been widely used in various fields, has important effect in lightning protection.The quality of its state directly affects its lightning protection effect, thereby the safety of protected equipment is brought to hidden danger.
The overcurrent protective device of existing SPD adopts fuse or circuit breaker conventionally, for disjunction SPD fault paths.But when SPD cross flow short-circuit, power current by time, its current value does not likely reach the startup value of overcurrent protective device, overcurrent protective device is failure to actuate, and causes power current to continue to pass through, lightning protection component heating makes SPD on fire.So overcurrent protective device exists serious blind area to the protection of SPD, in this region, overcurrent protective device is failure to actuate, cannot disjunction SPD fault paths.
Summary of the invention
In order effectively to solve the protection blind zone problem of existing overcurrent protective device to SPD, the present invention proposes a kind of safe and reliable Novel electric surge protector for power-supply system.
The present invention is by the following technical solutions: the present invention is the surge protector for power electronic circuits system, and described surge protector mainly comprises current sensor, relay, flow plug, link gear, lightning protection component and section breaker.
Described lightning protection component and section breaker series connection, flow plug and current sensor and relay cooperating in bypass in surge protector, can make thunder and lightning surge normally release, and can cut off again power current more than 3A, safe and reliable.
Described current sensor, relay, flow plug, link gear, lightning protection component and section breaker, be all arranged in a housing, is an overall Novel electric surge protector.
The invention is characterized in:
1. this Novel electric surge protector has solved the protection blind zone problem of overcurrent protective device;
2. this Novel electric surge protector is by integrated to current sensor, relay, flow plug, link gear, lightning protection component and section breaker and one, be loaded on housing, can meet the requirement of power consumption equipment to surge protector discharge capacity, response time and three indexs of voltage protection level, strengthen the reliability of equipment;
3. in the time that thunder and lightning surge current flows through, described current sensor does not respond high-frequency current, and relay can not be driven, thereby guarantees that SPD normally works, the thunder and lightning surge of releasing.Flow restricter has inhibitory action to high frequency lightning current simultaneously, presents high impedance, and protection relay is not subject to the shock effect of thunder and lightning surge;
4. in the time that lightning protection component inefficacy short circuit, power current flow through SPD, this low-frequency current can and drive relay by current sensor perception, makes accessory pathway conduction circuit turn-on.Flow restricter presents Low ESR under low-frequency current simultaneously, and power current flows into bypass, makes the magnetic force that produces unshakable in one's determination drive linkage, pulls open section breaker, cuts off SPD path.
Accompanying drawing explanation
Fig. 1 is embodiments of the invention structural representation.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
As shown in Figure 1, the 1st, section breaker, the 2nd, spring, the 3rd, current sensor, the 4th, lightning protection component, the 5th, flow plug, the 6th, relay, the 7th, link gear, the 8th, shell.
The present invention is the surge protector for power electronic circuits system, and described surge protector mainly comprises current sensor, relay, flow plug, link gear, lightning protection component and section breaker.
Described current sensor (3) can detect power frequency (low frequency) the electric current more than 3A flowing through on SPD path, drives relay (6), makes bypass circuit conducting.Its induction to high frequency lightning current has inhibitory action, can not drive relay (6).This current sensor (3) can adopt silicon steel sheet to do the iron core of iron ring.
Described flow plug (5) can be made up of electric components such as resistance, inductance, electric capacity, when low frequency (power frequency) electric current flows through, it presents Low ESR, guarantee that power current flows through bypass, make the magnetic drive link gear (7) that produces unshakable in one's determination, drive section breaker (1), disjunction SPD path; In the time that high frequency lightning current flows through, it presents high impedance, and protection relay (6) is not subject to thunder and lightning surge shock effect.
Described relay (6) can be made up of electric components such as controllable silicon, photoelectric relay, semiconductor switchs, the current drives closure that it is detected by current sensor (3).Only in the time that power current flows through SPD, current sensor just can drive its closure, and high frequency lightning current can not be responded to by this current sensor (3).
Described link gear (7), by the effect of magnetic force unshakable in one's determination, can drive section breaker (1), thus disjunction SPD path.
Described section breaker (1), after link gear (7) action, can make circuit disconnect by the pulling force of spring (2).
