Lower limit and upper limit.Inserted block 2 removably connects with lightning protection device shell 1, further increases lightning protection device and changes just
Victory；It addition, inserted block 2 is after being plugged in the first slot of breaker body housing, under inserted block 2 is formed by the bottom of the first slot
Spacing, the top in plug-in mounting chamber 12 forms upper limit to inserted block 2, although for Split type structure, but after still ensure that assembling
Structural stability.
The external hanging type lightning protection device of the present embodiment also include being electrically connected to described lightning protection circuit, for showing described lightning protection
At least one signal lamp whether device is destroyed by lightning surge, at least one signal lamp described is located at described shell 1
Outside.When lightning surge is too big, to such an extent as to lightning protection device protects chopper and self damages, but now product still can normal work
Make, providing the user with electric energy, if changed not in time, when thunder and lightning is attacked again, may just damage Aftercurrent protection circuit breaker
Body, causes large-area power-cuts, needs to change Aftercurrent protection circuit breaker, and task becomes weight, and problem complicates.And this reality
With novel, signal lamp is set by increasing signal output, when lightning protection device damages, and which phase signal lamp may indicate that
Destroyed by lightning surge and cause losing efficacy, it can in addition contain signal output, can see outside power distribution cabinet whether lightning protection device is at lightning surge
The most whether have and damage this situation lost efficacy, it is simple to electrician discovers, and changes in time.
As it is shown in figure 5, described lightning protection circuit includes three identical unit modules, each unit module includes the first temperature
Fuse FU1, varistor RV1, the second temperature fuse FU11, these three components and parts are connected across in being encapsulated in described shell 1 body
For surge protection and the pressure-sensitive signal of offer between phase line and the zero line of power supply.
Each unit module also includes a diode D1, a current-limiting resistance R1 and a LED 1, three
Individual element is connected in series in the instruction between pressure-sensitive instruction output pin and zero line for pressure-sensitive duty；Three unit modules
Second temperature fuse series connection after be drawn out to the terminal SX1 signal designation for pressure-sensitive damage.
Described product supports the use with aftercurrent action protecting action breaker when using, such as Fig. 5, the A of correspondence, B, C,
N is connected on end of incoming cables A, B, C, N of residual current action breaker, and during normal work, the display lamp of corresponding unit lights SX1 end
Son conducting, represents that protection module is working properly, when residual current operated protective device power circuit is by the pressure-sensitive electricity of corresponding unit when being struck by lightning
Resistance is by thunderbolt voltage clamp to a safe voltage value thus protects residual current protection action chopper not damage；Protection process
In when certain unit pressure sensitive voltage damages thermo-fuse FU1, the FU11 in corresponding unit be heated fusing, the display lamp of corresponding unit puts out
Going out, terminal SX1 disconnects simultaneously, and user can be according to the quality of the two signal decision module.
Further, this utility model also provides for the embodiment of a kind of chopper with external hanging type lightning protection device, this reality
The chopper executing example includes that breaker body and lightning protection device, described lightning protection device are the external hanging type lightning protection dress in above-described embodiment
Put.
The first grafting of inserted block 2 with described lightning protection device it is provided with along the longitudinal direction on the housing 3 of described breaker body
The first slot that portion 21 is corresponding, described first slot is suitable to the first Plug Division 21 and is vertically plugged in wherein, described first grafting
The dual-side 211 in portion 21 forms snap-fit engagement with the dual-side of described first slot.
Specifically, the dual-side of the first slot of described breaker body is inside towards described external hanging type lightning protection device direction
The inclined-plane that portion tilts, this inclined-plane is the most adaptive with the inclined-plane of described first slot, when the first Plug Division 21 is plugged in described first
After slot, both hypotenuses form the interface arrangment mutually kept out, thus prevent inserted block 2 from deviating from from the first slot.
Obviously, above-described embodiment is only for clearly demonstrating example, and not restriction to embodiment.Right
For those of ordinary skill in the field, can also make on the basis of the above description other multi-form change or
Variation.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus extended out or
Change among the protection domain still in this utility model creation.
