Abstract
The utility model relates to a novel surge protector, mainly comprising a current sensor, a relay, a choke, a linkage mechanism, a lightning protection element, and a breaking switch. The lightning protection element and the breaking switch are connected in series. The choke works cooperatively with the current sensor and the relay and controls the breaking switch through a bypass, thereby not only enabling lightning surges to be discharged normally but also cutting out power frequency current above 3 A in a safe and reliable manner. The novel surge protector is convenient in installation and strong in reliability, and jumps out of a blind area in a conventional SPD over-current protection mode.
Description
Technical field
The utility model belongs to the surge protection technical field of electronic electric equipment.
Background technology
Thunder and lightning is a kind of special weather phenomenon of aloft being discharged and being caused by charged cloud.Thunder and lightning is the major reason that causes electronic equipment to damage, and it threatens the safe and stable operation of every field electronic informations such as building, railway, civil aviaton, communication, industry control, military affairs.On metallic circuits such as the power line that is 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 then directly influences its lightning protection effect, thereby the safety of protection equipment is brought hidden danger.
The overcurrent protective device of existing SPD adopts fuse or circuit breaker usually, is used for disjunction SPD fault paths.But when SPD cross flow short-circuit, power current by the time, its current value might not reach the startup value of overcurrent protective device, overcurrent protective device is failure to actuate, and causes power current to continue to pass through, the lightning protection component heating makes SPD on fire.So there is serious blind area in overcurrent protective device to the protection of SPD, overcurrent protective device is failure to actuate in this zone, can't disjunction SPD fault paths.
The utility model content
In order effectively to solve the protection blind zone problem of existing overcurrent protective device, the utility model proposes a kind of safe and reliable novel surge protector that is used for power-supply system to SPD.
The utility model is by the following technical solutions: the utility model is the surge protector that is used for the power electronics line 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 the surge protector can make the thunder and lightning surge normally release, and can cut off the above power current of 3A again, and is safe and reliable.
Described current sensor, relay, flow plug, link gear, lightning protection component and section breaker all are arranged in the housing, are the novel surge protectors of an integral body.
Of the present utility model being characterised in that:
1. this novel surge protector has solved the protection blind zone problem of overcurrent protective device;
This novel surge protector with current sensor, relay, flow plug, link gear, lightning protection component and section breaker integrated and one, be loaded on housing, can satisfy the requirement of power consumption equipment, strengthen the reliability of equipment surge protector discharge capacity, response time and three indexs of voltage protection level;
3. when the thunder and lightning surge current flow through, described current sensor did not respond high-frequency current, and relay can not be driven, thereby guaranteed SPD operate as normal, the thunder and lightning surge of releasing.Flow restricter has inhibitory action to the high frequency lightning current simultaneously, presents high impedance, and protection relay is not subjected to the shock effect of thunder and lightning surge;
When lightning protection component inefficacy short circuit, when power current flows through SPD, this low-frequency current can and drive relay by the current sensor perception, makes the conducting of bypass order wire circuit.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, draws back section breaker, cuts off the SPD path.
Description of drawings
Fig. 1 is an example structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
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 utility model is the surge protector that is used for the power electronics line 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 above power frequency (low frequency) electric current of 3A that flows through on the SPD path, drives relay (6), makes the bypass circuit conducting.Its induction to the 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, and low frequency (power frequency) is when electric current flows through, and 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; When the high frequency lightning current flow through, it presented high impedance, and protection relay (6) is not subjected 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, and it is by the detected current drives closure of current sensor (3).Only current sensor just can drive its closure when power current flows through SPD, and the high frequency lightning current can not be responded to by this current sensor (3).
Described link gear (7) can drive section breaker (1) by the effect of magnetic force unshakable in one's determination, thus disjunction SPD path.
Described section breaker (1) is after link gear (7) action, and the pulling force by spring (2) can make circuit disconnect.
