Embodiment
Contrast accompanying drawing below, by the description to embodiment, to the specific embodiment of the present invention as related control system, mutual annexation, and implementation method, be described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present invention, technical scheme.
A kind of power supply output test board, this test board comprises test board body, alarm unit, incoming power loop, power supply output loop, described incoming power loop is connected to corresponding power supply output loop by different disposal circuit.The high 1030mm of this power supply output test wide 500mm of director 735mm, adopt plane operations, highlight design as Fig. 1, meet normal human's height design, can stand on the plane drilling output specification that elects, on riser, check out-put supply specification by display device.Below operator's console left and right, 8 kinds of specification power supply output connection jacks are installed, are facilitated the specification power supply that in debug process, directly selection needs as required directly to insert and can use with plug, easy-to-connect, safety.
Test board also comprises the wheel mechanism that is arranged on test board bottom.Described power supply output loop comprises eight electric power loops of the first specification to the eight specifications.Described the first specification power supply output loop is for analog power lacuna.The described second to the 6th specification power supply output loop is for converting Switching Power Supply to DC220V, DC110V and tri-kinds of supply units uses of DC24V by AC380V.Described the 7th specification power supply output loop is exported 4～20mA current signal by intelligent instrument.Described the 8th specification power supply output loop is for detection of the reading degree of accuracy of switch cubicle instrument.
Many specifications power supply output test board mainly designs by incoming power loop, eight kinds of specification power supply output loop Liang great departments and forms.As shown in Figure 2 and Figure 3, the output of eight kinds of specification power supplys be respectively 1, AC380V; 2, DC220V; 3, DC110V; 4, DC24V; 5, AC220V; 6, AC110V; 7,4～20mA; 8,0～20A.Its course of work is: gather an AC380V power supply to incoming power major loop, and then be dispensed to eight feeder assemblies.Each control loop is responsible for 380VAC power supply to convert power supply corresponding to various loops to by button control, realizes the power supply that low-voltage intelligent switch cubicle is provided automatically to all size, and this circuit has the feature of the unified output of concentrated circuit simultaneously.
Incoming power major loop as shown in Figure 4, this test board incoming power loop, in the time that draw AC380V power supply and be connected to test board in the external world, test board panel will have pilot lamp instruction, when the adhesive of major loop contactor, the buzzer warning lamp of installing on test board, can send chimes of doom and warning light, to remind the existing electricity of staff's test board, when operation, should take care.
As shown in Figure 5, this loop Main Function is to provide AC380V and uses to switch cubicle incoming power in the first specification out-put supply loop.We are in the time of design; consider in the time of test power cabinet; we want analog power phase shortage; so we pass through to use two contactors at major loop; in control loop, add button; realize power phase shortage, detect default-phase protection function as inner in the intelligent element such as soft starter, frequency converter as object to reach.So we are in test convenient, safety when power cabinet.
Second and third, four, five, six, specification out-put supply loop as shown in Figure 6; on protective relaying device, power supply generally can use by using DC220V and DC110V; the power supply of some intelligent elements such as PLC, motor protector often can use DC24V; so we are in when design, by second and third, four feeder assemblies are respectively by using Switching Power Supply to convert AC380V to DC220V, DC110V and tri-kinds of power supplys of DC24V for device.
The 7th specification out-put supply loop is to export 4～20mA current signal by intelligent instrument, and this current signal is of wide application, and such as utilizing to 4～20mA current signal of frequency converter input, motor speed is regulated etc.
The 8th specification out-put supply loop as shown in Figure 7, this loop is mainly the degree of accuracy of the reading of detector switch cabinet instrument, we make adjustable 0～20A current signal of its output by isolating transformer, adjustable resistance in test carriage, by its signal loading to current transformer in switch cubicle, whether then we observe in switch cubicle the variation of instrument numerical value consistent with adjustable current signal, thereby judge accuracy of instrument.
Professional can also further recognize, the execution step of describing in conjunction with embodiment disclosed herein, can realize with electronic hardware, computer software or the combination of the two, these functions are carried out with hardware or software mode actually, depend on application-specific and the design constraint of technical scheme.Professional and technical personnel can realize described function with distinct methods to each specifically should being used for, but this realization should not thought and exceeds scope of the present invention.
The present invention is not limited to above-mentioned specific embodiment; do not departing under spirit of the present invention and real situation thereof; those of ordinary skill in the art can make according to the present invention various corresponding changes and distortion; these are tackled mutually the amendment that the present invention carries out or are equal to replacement, and it all should be encompassed in the middle of the scope of claim protection of the present invention.
