Specific embodiment
A kind of multi-functional back-up protection device is present embodiments provided combined with Figure 1 and Figure 2, and the back-up protection device for SPD produces
Product, including lightning current are released component, low current detection part, execution unit, indicate indicator, warning piece etc..Wherein, lightning current
Release component, low current detection part, execution unit is sequentially connected, and is cooperated and is completed the conducting diverter function of core；It executes
Component drives indicate indicator and warning piece, completes instruction and warning function.
Specifically, lightning current releases component for lightning current of releasing.Low current detection part is deteriorated for detecting SPD
When the power frequency continued flow signal that generates.Execution unit is for executing current turns ON or disjunction task.Indicate indicator is used to indicate electric current
The state with disjunction is connected, red, which represents, to be connected, and electriferous state is warned；Green represents disjunction, prompts safe condition.Warning piece
It alarms for breakpoint, for the application environment of SPD, when circuit is normal, no current in multi-functional back-up protection device circuit works as short circuit
When abnormal, there is abnormal current in this circuit, multi-functional back-up protection device executes the movement of disjunction circuit, and warning piece exports at this time
Alarm is reminded and warning circuit failure.
Indicate indicator mainly includes handle 1, U-shaped bolt 2, lever 3, microswitch 4, PCB circuit board 5, PCB connecting terminal 6.
In conjunction with Fig. 3, lever 3 includes main body, and main body is equipped with shaft 302；Main body extends to form a body of rod, the body of rod to the left
Front end is equipped with pin hole 304；Main body upper end is equipped with red green indicator 303, is equipped with fixing axle 301 on the right side of main body.Fixing axle 301 can be with
Be with the plastic part of 3 main body integral type of lever, be also possible to the metallic rod that secondary operation is inlayed.
Lever 3 is installed inside the shell by shaft 302, and U-shaped bolt 2 passes through pin hole 304 and connect lever 3 with handle 1, handle
1 connection execution unit, 1 upper end of handle is exposed to shell exterior.The elastic slice of microswitch 4 is connect with fixing axle 301, microswitch 4
Connection PCB wiring board 5,5 connection PCB connecting terminal 6 of PCB circuit board, PCB connecting terminal 6 connect warning piece.
Microswitch 4 is fixed on the shell, the fixed bit of shell set there are two the hole with microswitch 4 match it is convex
Platform can be easily plugged into microswitch 4, convenient for fixed microswitch 4, make consolidating for the elastic slice of microswitch 4 and lever 3
The connection close to each other of dead axle 301.When not needing warning function, this boss does not influence other function.
Shell side is equipped with the groove of positioning, and positioning groove is for installing PCB connecting terminal 6, convenient for connection warning device.
When not needing alarm work energy, this groove can be blocked with baffle, and appearance outer surface of outer cover is consistent, do not influence its beauty.
When back-up protection device access circuit in after, as shown in Figure 1, handle 1 clockwise by I rotation direction II when, for combined floodgate
It powers on.Handle 1 and lever 3 are connected by U-shaped bolt 2, and the tie point of lever 3 and U-shaped bolt 2 is located at 3 left side of lever, and lever 3 turns
Axle position will drive lever 3 and rotate counterclockwise in the right side of the tie point, therefore when handle 1 rotates clockwise.Fixing axle 301,
What red green indicator 303 was fixed as one with lever 3, therefore during handle 1 rotates, drive fixing axle 301 and red
Green indicator 303 rotates together.Farther out because of fixing axle 301 and the red center of circle of the green indicator 303 from its shaft 302, the mistake of rotation
Cheng Zhongneng forms certain displacement.
Fixing axle 301 is on the right side of shaft 302, and when lever 3 rotates counterclockwise, fixing axle 301 is shifted up.Drive with
The elastic slice of connected microswitch 4 also move up, compression elastic slice makes microswitch 4 go off state by closure.Again by
This state is sent to warning piece by wiring board 5 and PCB connecting terminal 6.
Red green indicator 303 is in the upside of shaft 302, and when lever 3 rotates counterclockwise, red green indicator 303 is to left position
It moves.There are two colors for red 303 top surface of green indicator, red for the left green right side, have a window 7 on shell right above embolium, such as Fig. 4 institute
Show.Drive red green indicator 303 to after left dislocation in lever 3, former red position goes to the position of embolium, and window is designated as red
Color, warning is dangerous, and product has charged.
When low current detection part detects that SPD has the failures such as power frequency continued flow, conduction to execution unit, then disjunction is electric
Road.Handle 1 rotates counterclockwise at this time, when by II rotation direction I, powers off for separating brake, as shown in Figure 2.It is clockwise to will drive lever 3
Rotation.
Fixing axle 301 is to bottom offset at this time.It drives the elastic slice for the microswitch 4 being attached thereto also to move down, discharges bullet
Piece makes microswitch 4 change from disconnected to closed state.This state is sent to alarm department by wiring board 5 and PCB connecting terminal 6 again
Part is allowed to alarm.
Red green indicator 303 is displaced to the right.The position of former embolium is moved to red position.Window 7 is designated as green, produces
Product power-off, while circuit abnormality is also represented, it needs to overhaul.
In the present embodiment, the red green color on red green indicator 303 can use retroussage, can also be using corresponding red
Material and ink cooperatively form red green indicating piece.
Multi-functional SPD back-up protection device provided in this embodiment, integrates instruction, alarm, tripping function.When promotion hand
Handle 1 drives lever 3 to rotate by U-shaped bolt 2, and being attached on lever 3 has red green indicator 303 and fixing axle 301, when 3 turns of lever
When dynamic, red green indicator 303 is followed by a starting, by the fixation window on shell, it can be observed that the transformation of color；Simultaneously
The fixing axle 301 being attached on lever 3 also rotates together, and drives the elastic slice for the microswitch 4 being connected with fixing axle 301, makes
Microswitch 4 changes open/close state, realizes alarm；It drives execution unit again simultaneously, makes the direct trip of SPD back-up protection device simultaneously
Disjunction circuit；The apparatus structure is simple, transmission link is few, high reliablity, low cost.The SPD back-up protection device of the device is configured,
With compact, full-featured, performance indicator is reliable and the applicability characteristics such as extensively.
It should be understood that up, down, left, right, before and after, front, the back mentioning or may mention in the present specification
The positional terms such as face, top, bottom are defined relative to each construction shown in the drawings, they are opposite concepts,
It is therefore possible to can different location according to locating for it, different use state and correspondingly changed.So also should not be by this
A little or other positional terms are construed to restricted term.
The above, the only preferred embodiment of the utility model, it is in any form and substantive not to the utility model
On limitation, it is noted that for those skilled in the art, in the premise for not departing from the utility model method
Under, several improvement and supplement can be also made, these are improved and supplement also should be regarded as the protection scope of the utility model.It is all ripe
Professional and technical personnel is known, in the case where not departing from the spirit and scope of the utility model, when using disclosed above
Technology contents and the equivalent variations of a little variation, modification and evolution made, be the equivalent embodiment of the utility model；Together
When, all substantial technologicals according to the utility model to the variation, modification and evolution of any equivalent variations made by above-described embodiment,
