Description
Technical field
The invention belongs to the surge protection technical field of electronic electric equipment.
Background technology
Thunder and lightning be by powered cloud discharge in the air caused by a kind of special weather phenomenon.Thunder and lightning is to cause electronic equipment
The major reason of damage, it threatens the peace of the every field electronic informations such as building, railway, civil aviaton, communication, industry control, military affairs
Full stable operation.Surge protection is installed on the metallic circuits such as the power line, signal wire and control line being connected with electronic equipment
Device (SPD) is one of important measures of lightning protection.Surge protector has been widely used in various fields, has in lightning protection
Play the role of important.The quality of its state then directly affects its lightning protection effect, so as to carry out hidden danger to the safety belt of institute's protection equipment.
Existing SPD overcurrent protective device generally uses fuse or breaker, for disjunction SPD short trouble paths.
But when power system failure, SPD cross flow short-circuit, power current by when, its current value is possible to not reach overcurrent protective device
Initiation value, overcurrent protective device is failure to actuate, and causes power current to continue through, and lightning protection component heating SPD is on fire.If by excessively stream
The initiation value of protection device selects small, though can start, is difficult to the impact for resisting lightning current, causes SPD can not normally release thunder and lightning
Stream.Therefore protection of the existing overcurrent protective device to SPD has serious blind area, overcurrent protective device is failure to actuate in this region,
Can not disjunction SPD fault paths.Other existing overcurrent protective device and SPD are separately installed, it is necessary to larger installing space, and line
Road coiling is complicated, increases residual voltage, threatens by protection equipment.
The content of the invention
The present invention integrates lightning protection component and overcurrent protective device, and residual voltage is lower, improves lightning protection effect, effectively solves
State problem.
The present invention uses following technical scheme：The present invention is for the surge protector in power electronic circuits system, institute
Stating surge protector includes lightning protection component and overcurrent protective device, and both are connected in series, and are arranged in a housing, are one whole
The new surge protector of body.
The overcurrent protective device mainly include break contact (static contact and moving contact), tripping mechanism, step electromagnet,
Combined floodgate spanner, locking board, current sensor, power current suppressor, delay step electromagnet, arc-chute, arc extinguishing magnetic blow-out plate and
Upper and lower terminals.
The upper terminals are connected with break contact static contact, and static contact is connected with tripping mechanism moving contact, and moving contact is worn
Over-current sensor is connected in series with power current suppressor, and power current suppressor is connected with lightning protection component, is finally connect with
Line end is connected；Current sensor output is connected to delay step electromagnet, and the motion of delay step electromagnet iron core can be pushed away
Dynamic locking board, so as to drive whole tripping mechanism to make moving contact be separated with static contact；Combined floodgate spanner closing by hand can be passed through；Arc extinguishing
It is separately the electric arc produced with static contact that grid and arc extinguishing magnetic blow-out plate, which are used to eliminate moving contact,.
It is a feature of the present invention that：
1. this new surge protector solves the protection blind zone problem of existing overcurrent protective device；
2. overcurrent protective device is integrated in one by this new surge protector with lightning protection component, residual voltage is effectively reduced, is subtracted
Few installing space.
3. this new surge protector be one can closing by hand new surge protector；
4. when power system failure, power current flow through, lightning protection component failure is short-circuit, the work in this reserve protection
Frequency current suppressor can play inhibitory action to the electric current then flowed through, and causing can by the power frequency electric flow valuve of lightning protection component
Slow to rise, the time of fire incident occurs for extension SPD；The step electromagnet that is delayed simultaneously passes through pulse number stepping, Millisecond
Quick-action after delay, promotes locking board, drives tripping mechanism, opens break contact, so as to cut off SPD paths, plays back-up protection
Effect；
5. when lightning surge electric current flows through, the delay step electromagnet is introduced into also without pulse number stepping
Delay stage, lightning current has terminated, and tripping mechanism is failure to actuate, it is ensured that SPD normally releases lightning current.

Fig. 3 is the principle schematic of first, second embodiment of the invention.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
As shown in Figure 1, 2, 3,1 is upper terminals, and 2 be break contact, and 3 be tripping mechanism, and 4 be combined floodgate spanner, and 5 be lock
Plate, 6 be current sensor, and 7 be power current suppressor, and 8 be lower terminals, and 9 be shell, and 10 be lightning protection component, and 11 be delay
Step electromagnet, 12 be arc-chute, and 13 be arc extinguishing magnetic blow-out plate, and 14 be moving contact, and 15 be static contact.
Fig. 1 is first embodiment of the present invention structural representation, wherein lightning protection component (10) and power current suppressor (7)
Level connection joint.
Fig. 2 is second embodiment of the present invention structural representation, wherein lightning protection component (10) and power current suppressor (7)
Mounted on top.
Fig. 3 is the principle schematic of first, second embodiment of the invention.
The present invention is for the surge protector in power electronic circuits system, the surge protector lightning protection component and mistake
Flow protection device；The overcurrent protective device mainly includes break contact (static contact and moving contact), tripping mechanism, stepping electromagnetism
Iron, combined floodgate spanner, locking board, current sensor, power current suppressor, delay step electromagnet, arc-chute, arc extinguishing magnetic blow-out plate
With upper and lower terminals.
The upper terminals (1), break contact (2), power current suppressor (7), lightning protection component (10), lower terminals
(8) it is connected in series.
The electric current that the current sensor (6) can be flowed through in induction line, and current signal is exported to delay stepping
Electromagnet (11).
The power current suppressor (7), is series between upper and lower terminals, has suppression to make to the power current flowed through
With can be that lightning protection component failure is on fire below race against time.
The delay step electromagnet (11) can distinguish defeated according to current sensor (6) induced lightening electric current and power current
The time difference of the signal gone out, realizes a kind of parametrization control.Power current is the periodic wave of Millisecond, and be delayed stepping electromagnetism
Iron can pass through pulse number stepping, and quick-action after Millisecond delay promotes locking board (5), drives tripping mechanism (3), disjunction SPD
Path, plays a protective role；Lightning current is fast-changing Microsecond grade pulse, and delay step electromagnet (11) can not complete pulse
Number stepping, into delay stage, lightning current has passed through, so tripping mechanism (3) is failure to actuate, it is ensured that lightning current is smoothly released.
The combined floodgate spanner (4) separates when moving contact (13) with static contact (14), i.e., after overcurrent protective device starts, can lead to
Cross combined floodgate spanner (4) manually to close a floodgate (after determining that SPD is not damaged), moving contact (14) is resumed contacts with static contact (15),
So that unspoiled SPD takes back circuit again.
The arc-chute (12) and arc extinguishing magnetic blow-out plate (13) constitute the arc-control device of this new surge protector, for eliminating
The electric arc that moving contact (14) is produced when being separated with static contact (15).
