Square coil can be used for the breaker of no sampling resistor, and now, the inlet wire linkage section and breaker enter
Line terminals are integral, are that punching press, bending obtain on same copper coin in processing.
The principle of this programme is：
Current sample, analysis contrast and the general electricity made by the control unit containing computation chip of monitoring to breaker
Road is completed, such as the control pole of intelligent breaker.
In order to ensure in breaker closing and off-state computation chip in "on" position, in general, computation chip
Supply lines be typically connected on the end of incoming cables of breaker.And if sampling resistor is arranged on the leading-out terminal of breaker, when breaker breaks
If opening back loading side there is induced voltage, the sampling resistor signal wire pin of computation chip and energization pins there may be more than
The common-mode voltage of computation chip operating voltage, this common-mode voltage are possible to burn computation chip.In order to solve this problem, this
In method, the sampling resistor of breaker will be arranged on the end of incoming cables of breaker.
The interior spatial structure of general breaker is analyzed, current sampling resistor is suitably arranged on entering for circuit breaker electric magnetic mechanism
In line terminals.According to circuit breaker current sample required precision and copper conductor sectional area, big specification (such as more than 63A) it is small-sized
The sampling resistor (by taking copper-manganese as an example) of breaker probably needs 5mm length, and additional two pins and sampling resistor both ends need
Length of straight flange demand, then current sampling resistor need 10mm length of straight flange.
Current sampling resistor is set to have two ways on breaker input terminal：
One kind is --- current sampling resistor is set (such as on the horizontal straight flange of input terminal (resistance and iron core diameter parallel)
Fig. 2), this mode needs case for circuit breaker length to increase more than 10mm, and in general, intelligent breaker requires limitation length
(such as below 80A breakers are limited in 80~90mm to degree by national grid standard, and more than 80A breaker length is limited in 95
Between~100mm), this setup of sampling resistor compares in practical operation to be difficult to, it is necessary to its to breaker
Its structure and circuit are redesigned.
Another kind is --- current sampling resistor is set in the vertical edges (resistance is vertical with iron core axis) of input terminal
(such as Fig. 5,7).It has been investigated that current circuit breaker electric magnetic mechanism structure design make it that the vertical side length of input terminal is basic
All between 4~6mm (such as Fig. 3), hung down without enough lengths of straight flange to set current sampling resistor, it is necessary to lengthen input terminal
Length of straight flange.And after input terminal vertical edges lengthen, the spot welding position of input terminal and coil pin is just needed toward core insulation
Sleeve pipe direction is moved, and input terminal has blocked the mounting hole of iron core and core insulation sleeve pipe after movement so that input terminal and line
Punctuate postwelding iron core and core insulation sleeve pipe can not assemble, so needing case for circuit breaker to lengthen, input terminal is toward away from iron
A segment distance is moved to increase the space between input terminal vertical edges and core insulation sleeve pipe in the direction of core insulation sleeve pipe so that
Unshakable in one's determination and insulating sleeve can first be assembled and then spot welding is carried out to input terminal and coil again.Simultaneously current structure input terminal
Probably there is 3~4mm space between vertical edges and core insulation sleeve pipe, can be carried out as long as the space increases to 5mm or so
Spot welding operation, so shell need to only lengthen 1~2mm, this is easier to realize in engineering practice.
For more than 80A breaker, its coil is formed using lenticular wire (enamel-covered wire) coiling, and lenticular wire can not be wanted by this
Bending pin is sought, so more than 80A breaker input terminal and the solder joint of coil are all in the middle part of insulating sleeve at present, Wu Fashi
Core insulation sleeve pipe is now first assembled at spot welding (such as Fig. 4).So for more than 80A breaker, this programme design is rushed by copper coin
The square coil formed is pressed to replace the coil of enamel-covered wire coiling.And coiling is made into coil pin after stamping parts becomes can
Energy (such as Fig. 5).
The square coil that copper coin punching press obtains is equally applicable to below 80A breaker.
This square coil can be used for the breaker of no sampling resistor, now, the inlet wire linkage section and breaker
Input terminal is integral, is that punching press, bending obtain on same copper coin in processing.
This square coil solves following problem：
1st, the not accurate and unstable nothing after causing electromagnetic mechanism welding of the too thick coiling size of the coil of big specification breaker
The problem of method is assembled or needs secondary reshaping and bring production efficiency slow；
2nd, the coil of big specification breaker it is too thick and in pin bending cracking or can not bending the problem of；
3rd, the problem of coiling causes spot welding size to be forbidden in spot welding because being positioned without smooth locating surface.
The principle of square coil is that the circular coil formed originally by enamel-covered wire coiling is designed to be stamped to form by copper coin
Square coil, its manufacture method becomes to be processed with sheet metal mould so that the dimensional accuracy and dimensional uniformity of coil obtain matter
Leap.Because square coil is stamped to form by copper coin, the pin at its coil both ends is obtained by blanking of copper coin, without folding
It is curved, therefore just there is no cracking during bending problem.After other coil is become squarely, is become stamping by coiling by circle, whole line
Circle is exactly square-folded profile, and when the spot welding of electromagnetic mechanism is processed, square-folded coil shape is very beneficial for spot welding and determined
Position or the realization of automation spot welding., can be according to being actually needed for product coil design into after by copper coin punch forming
The input terminal of coil and breaker designs integrally, i.e., breaker input terminal and coil is become by two original parts
Into a part, not only reduce the management work of part and save together with point welding process, also improve the chi of electromagnetic mechanism
Very little precision, it is more beneficial for the Automated assembly of electromagnetic mechanism.
The technical program has the beneficial effect that：Success is current sample in the case of the case for circuit breaker length that moves within narrow limits
Incorporating resistor realizes the collection and control of circuit breaker electric stream information inside breaker.
