Embodiment
Contrast accompanying drawing below, by the description to embodiment, to embodiment of the present utility model as involved control system, mutual annexation, and implementation method, be described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.
A kind of power supply exports test board, and this test board comprises test board body, alarm unit, incoming power loop, power supply output loop, and described incoming power loop is connected to corresponding power supply output loop by different disposal circuit.This power supply exports test director 735mm wide 500mm height 1030mm, adopt plane operations, highlight design as Fig. 1, meet normal human and highly design, plane drilling can be stood on to elect output specification, riser checks out-put supply specification by display device.About operator's console, 8 kinds of specification power supply output connection jacks are installed in below, facilitate in debug process and directly select the specification power supply needed directly to insert can use with plug, easy-to-connect, safety as required.
Test board also comprises the wheel mechanism be arranged on bottom test board.Described power supply output loop comprises eight electric power loops of the first specification to the 8th specification.Described first specification power supply output loop is used for analog power lacuna.Described second to the 6th specification power supply output loop is used for AC380V being converted by Switching Power Supply to DC220V, DC110V and DC24V tri-kinds of supply units and uses.Described 7th specification power supply output loop exports 4 ~ 20mA current signal by intelligent instrument.Described 8th specification power supply output loop is used for the reading degree of accuracy of detector switch cabinet instrument.
Many specifications power supply exports test board major design and is made up of incoming power loop, eight kinds of specification power supply output loop Liang great departments.As shown in Figure 2 and Figure 3, what eight kinds of specification power supplys exported is 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 the power supply becoming various loop corresponding 380VAC Power convert by button control, realize power supply low-voltage intelligent switch cubicle being provided automatically to all size, and this circuit has the unified feature exported of concentrated circuit simultaneously.
Incoming power major loop as shown in Figure 4, this test board incoming power loop, when the external world draw AC380V power supply be connected to test board time, test board panel will have pilot lamp to indicate, when the adhesive of major loop contactor, the buzzer warning lamp that test board is installed, can send chimes of doom and warning light, to remind the existing electricity of staff's test board, should take care during operation.
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 when designing; consider when testing power cabinet; we want analog power phase shortage; so we pass through use two contactors at major loop; button is added in control loop; realize power phase shortage, detect for the purpose of default-phase protection function as inner in the intelligent element such as soft starter, frequency converter to reach.So we test power cabinet time convenient, safety.
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 design time, by second and third, four feeder assemblies respectively by use Switching Power Supply convert AC380V to DC220V, DC110V and DC24V tri-kinds of power supplys for device.
7th specification out-put supply loop exports 4 ~ 20mA current signal by intelligent instrument, and this current signal is of wide application, and such as can utilize to input 4 ~ 20mA current signal to frequency converter and regulate etc. motor speed.
8th specification out-put supply loop as shown in Figure 7, the degree of accuracy of this loop mainly reading of detector switch cabinet instrument, we make it export adjustable 0 ~ 20A current signal by isolating transformer, adjustable resistance in test carriage, by its signal loading in current transformer in switch cabinet, then we whether observe the change of instrument numerical value in switch cubicle consistent with adjustable current signal, thus judge accuracy of instrument.
Professional can also recognize further, in conjunction with the execution step that embodiment disclosed herein describes, can realize with electronic hardware, computer software or the combination of the two, these functions perform with hardware or software mode actually, depend on application-specific and the design constraint of technical scheme.Professional and technical personnel can use distinct methods to realize described function to each specifically should being used for, but this realization should not thought and exceeds scope of the present utility model.
The utility model is not limited to above-mentioned specific embodiment; do not departing under the utility model spirit and real situation thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the utility model; these are tackled amendment that the utility model carries out mutually or equivalently to replace, and it all should be encompassed in the middle of the scope of claim of the present utility model protection.
