Description
Technical field
The utility model relates to Distribution Automation Technology field, relates in particular to a kind of remote signalling plate for distribution feeder terminal.
Background technology
Along with developing rapidly of distribution automation, more and more higher for performance and the quality requirements of distribution power automation terminal.The design of tradition remote signalling plate, usually just takes some measures on electric to improve EMC performance at the circuit part of photoelectric coupled device, and these conventional electrical are improved means cannot produce the improved effect of non-electrical means, is difficult to meet people's requirement.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of remote signalling plate for distribution feeder terminal, the creepage distance having overcome between photoelectrical coupler input terminal and lead-out terminal is little, the defect of the damp and hot test weak effect of photoelectrical coupler alternation, voltage-withstand test poor performance.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of remote signalling plate for distribution feeder terminal, comprise pcb board, a plurality of photoelectrical coupler, described pcb board is provided with a gap, a plurality of described photoelectrical couplers are equidistant is intervally arranged into row, described in each, the both sides of photoelectrical coupler are respectively equipped with input terminal and lead-out terminal, a plurality of described photoelectrical couplers are all across described gap, and described input terminal and described lead-out terminal are welded on respectively on described pcb board and are positioned at the both sides in described gap.
The beneficial effects of the utility model are: by non-electric improving one's methods, withstand voltage properties while having improved the performance of photoelectrical coupler when the damp and hot test of alternation and voltage-withstand test, increase the creepage distance between photoelectric coupler output end and input terminal simultaneously, improved insulating property.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the width in described gap is 1～3mm.
Adopt the beneficial effect of above-mentioned further scheme to be: the wide meeting of width in gap causes photoelectrical coupler cannot cross over gap, the narrow meeting of width in gap makes creepage distance reduce to affect insulating property, and suitable gap width is conducive to improve the creepage distance of photoelectrical coupler.
Further, the width in described gap is 2mm.
Adopt the beneficial effect of above-mentioned further scheme to be: when gap adopts the width of 2mm, the performance of remote signalling plate is better.
Accompanying drawing explanation
Fig. 1 is the partial structurtes schematic diagram of a kind of remote signalling plate for distribution feeder terminal of the utility model.
In accompanying drawing, the list of parts of each label representative is as follows:
1, pcb board, 2, photoelectrical coupler, 3, input terminal, 4, lead-out terminal, 5, gap.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, the utility model comprises pcb board 1, a plurality of photoelectrical coupler 2, and the quantity of photoelectrical coupler is 1～20, and the quantity of photoelectrical coupler can arrange according to demand.Pcb board 1 is provided with a gap 5, between a plurality of photoelectrical couplers 2 with the equidistant row that are intervally arranged into, the both sides of each photoelectrical coupler 2 are respectively equipped with input terminal 3 and lead-out terminal 4, a plurality of photoelectrical couplers 2 are all across gap 5, and input terminal 3 and lead-out terminal 4 are welded on respectively the both sides that are positioned at gap 5 on pcb board 1.On input terminal 3 and lead-out terminal 4, be equipped with a pair of pin, pin is welded on pcb board 1, gap 5 is set on the pcb board 1 between the pin of input terminal 3 and the pin of lead-out terminal 4 and is conducive to increase the input terminal 3 of photoelectrical coupler and the creepage distance between lead-out terminal 4, gap 5 is set and can also prevents that on pcb board 1, adhering to impurity conduction affects insulating property, impurity cannot be attached on gap simultaneously.
The width in gap 5 is 1～3mm, the preferable width in gap 5 is 2mm, the length in gap 5 is according to the quantity setting of photoelectrical coupler but can not surpass the length of pcb board 1, it is long that the length in gap 5 is greater than the row that a plurality of photoelectrical couplers 2 form a line, and after a plurality of photoelectrical couplers form a line, all can be positioned at across gap 5 top in gap 5.
By gap 5 is set on pcb board 1, make this remote signalling plate stable effective when by as damp and hot in the alternation experiment of electromagnetic compatibility EMC test event, good pressure-resistant performance when carrying out voltage-withstand test, by being set, gap 5 increased the input terminal 3 of photoelectrical coupler 2 and the creepage distance between lead-out terminal 4, improved insulating property, made in the device course of work stable.And gap is set on pcb board, and simple to operation, cost is lower, and the beneficial effect of generation is obvious.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
