Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in accompanying drawing:
Fig. 1 is the structural representation of apparatus of the present invention;
Fig. 2 is the structural representation under apparatus of the present invention another visual angles;
Fig. 3 is apparatus of the present invention indicating light cover plate structure schematic diagram.
Embodiment
A kind of device that integrates signals collecting and pilot lamp as shown in Figure 1, 2, comprise base 1, three busbars, three current transformer 5 and cover plate 10, pilot lamp 6 and cover plates 8 thereof that are arranged side by side on base, current transformer 5 and be in the middle of hollow square structure, busbar comprises the A phase busbar 2, B phase busbar 3 and the C that are arranged side by side busbar 4 mutually, each busbar passes a current transformer 5 separately, busbar one end is exposed to the outside of base 1, and the other end is fixed by screws on base 1.
In order to gather the voltage of each phase, this device that integrates signals collecting and pilot lamp comprises that also three are adopted the line ball (not shown), be used for connecting current transformer and the busbar that interts therein, adopting line ball one end for every all is connected with the N line by the inner PCB of current transformer, the other end is welded on busbar, and adopt the middle resistance (not shown) of all connecting of line ball for every, can obtain the voltage of this phase line by the voltage of measuring this resistance.
Current transformer cover plate 10 is fixed on base 1 by four back-offs 101 provided thereon.
As shown in Figure 3, be the structural representation of indicating lamp cover plate of the present invention.In order to make power taking row 7 power taking from the busbar easily, preferably respectively establish a power taking row guiding 71 at the two ends of indicating lamp cover plate 8, this power taking row guiding is vertical pillar groove shape, is used for supporting and guiding power taking row to contact with busbar.Power taking row guiding 71 not only can support power taking row 7, can also arrange guiding 71 guiding power taking row 7 its corresponding busbars by power taking and contact, and namely guides power taking on the busbar of power taking row 7 from Current Transformer Assembly.Power taking row 7 one ends are fixed in pilot lamp 6 afterbodys by screw, and the other end arrange guiding 71 by power taking and stretched out, indicating lamp component and Current Transformer Assembly completed assembled to the base 1 after, power taking is arranged 7 and can be contacted with busbar.For make power taking row can be more steadily power taking from the busbar, can arrange 7 to power taking and further fix, as adopting buckles 72 to be fixed on indicating lamp cover plate 8 at power taking row 7 center sections.For further making power taking row 7 and busbar form good contact, power taking can be arranged 7 and form turn of bilge 73 with the contacted end of busbar, this turn of bilge 73 contacts with busbar formation face.
For ease of the installation and maintenance of pilot lamp, back-off 81 structures can be set on indicating lamp cover plate 8, indicating lamp cover plate 8 is fixed on base 1 by back-off 81.Certainly, in order to guarantee the reliability and safety of pilot lamp contact electricity getting, fixedly indicating lamp cover plate is on base 1 can to utilize in addition self-tapping screw 9, and the quantity of self-tapping screw can be 2, also can decide as required.
Above-mentioned alleged A, B, C are phase line, and the N line is the neutral line or center line.General A, B, C, N line busbar and PE busbar in power distribution cabinet all adopts busbar, busbar in use generally indicates phase look letter sign or scribbles the phase colored paint, A phase busbar is designated " Huang " look, B is " green " look mutually, C is " red " look mutually, the N line is " pale blue " look, and the PE bus is that " yellowish green " is double-colored.
Copper bar is made by copper material, claims again copper busbar, copper bus-bar or copper bus-bar, grounding copper bar, is a kind of conducting heavy current product, is applicable to the electro-engineerings such as high and low voltage electrical equipment, switch contact, controller switching equipment, bus duct.The copper bar cross section is the long conductor of rectangle or chamfering (or fillet) rectangle, plays a part carry electric current and be connected electrical equipment in circuit.What the quality requirements of copper busbar was carried out at present is GB/T 5585.1-2005 standard.
Arranged by the aluminium that is called that alumina based material is made, but the electric conductivity of copper is better than aluminium, in the situation that electric current is identical, the section ratio copper of aluminium is much bigger; Arranged by the silver that is called that silver material is made, although silver row electric conductivity is better than busbar, the cost that uses silver to arrange is expensive.Generally speaking, compare with aluminium row or silver row, copper bar has particularly obtained using widely in complete power distribution equipment at electrical equipment.Therefore, the copper bar preferably made by copper material of above-mentioned busbar.
The present invention integrates the device of signals collecting and pilot lamp applicable to various types of switches, because for dissimilar switch, only needs the busbar of replacing respective model namely applicable.
The current transformer lead-out terminal is in the bottom of base and in same plane, thereby can realize directly need not connecing secondary line to inserting with backboard PCB, and one-piece construction is compacter.
The current transformer that apparatus of the present invention adopt is tailor-made product, and volume is little, and three current transformers install side by side, makes compact conformation.When updating maintenance, only need the switch of respective electrical current transformer is disconnected, not only can not affect the operation of other loads, also can guarantee maintainer's handling safety.
Existing pilot lamp wiring is loaded down with trivial details, pilot lamp in apparatus of the present invention does not need wiring, but directly utilize power taking row contact power taking from the busbar, therefore, when pilot lamp being safeguarded replacing, only need indicating lamp cover plate is taken off, more finish changing to install in the device outside again and go back, the maintenance of can avoiding in the past cutting off the power supply affect load and normally moves and easily cause the problem of personal safety.
