The power box voltage selector of the present invention not only has the aforementioned advantages of convenient output voltage conversion, but also has appropriate protection measures to reduce the probability of damage to the electrical equipment. When we artificially insert a 220 V connector, if the voltage is When the selection button (2 0) is switched to the position of 4 40 V, an alarm bell will be triggered to achieve the effect of prompting the operator. If the voltage selected above is correct, but when the 4 40 V start button (2 2) is pressed, , It is in a state of no power output. On the other hand, when the connector of 4 0 0V is inserted, if the voltage selection button (2 0) is switched to the 2 2 0 V position, the alarm bell will also be triggered. The voltage is correct, but when the start button (2 1) of 220V is pressed, it can also be in a state of no power output; therefore, the above-mentioned protection measures provide proper power safety.

As for the internal circuit aspect of the present invention, as shown in the main circuit diagram of the third figure, the 220 V and 4 40 V power sources are respectively passed through non-fuse switches (N

Description of the invention (6) FBI) (NFB 2) and electromagnetic switch (MC 1) (MC 2), connect them in parallel, and then pass the third / fourth electromagnetic switch (MC3) (MC4) and Overheating the electrical relay (TH — RY1) (T Η — RY 2) to form two sets of three-phase output terminals (D ~ F) representing 220V and 44.0V, respectively. It is connected to the two sockets (30) (40) at the bottom of the drawing for outputting the corresponding voltage to the electrical equipment. There are also two terminal blocks (51) connected to 220V and 440V power supply below the drawing. ) (52), the R, S, and T terminals of the two terminal blocks (51) and (52) are the 2 2 0 V and 4 4 0 V output contacts that are not controlled by the φ circuit of this line, for connecting additional equipment , U, V, and W terminals on the two terminal blocks (5 1) (5 2) are used as backups. If DEF uses electricity to output to general loads (such as motors, heaters, etc.), UVW is suspended and not connected. Connectors The three ABC wires are also left unconnected. If DEF uses electrical output to the driver, such as inverters, controllers, ABC of the J connector is connected to the output of the driver, and UVW is connected to the load (such as motor, heating ), I.e. to the driving of the present invention, then the load is controlled by the driver. The control circuit for controlling these electromagnetic switches (MC 1 ~ MC 4) is shown in the fourth figure, and constitutes an automatic control loop with most relays or relays. The ingenious feature of the present invention is that: Use the extra pins (control pins) of the two connectors (3 1) (4 1) in the second figure to short-circuit some of the pins so that they are inserted into the control panel (1 0) After the socket (30) (40) of the

If I insert the first connector (3 1) representing 220V, and then connect the first relay (RY 1) through the GG point, at this time, if I rotate the voltage selection button (2 0) to 2 On the 20 V side, the first electromagnetic switch (MC 1) is energized, so the second electromagnetic switch (MC 3) can be energized and lighted together by pressing the 220 V start button (2 1). The first indicator light (1 5), that is, the 220V power supply on the left side of the third figure is connected to the DE F terminal, and the person who obtains the 220V power φ source at the first socket (30) is the same. After the second connector (41) is inserted, MC2 and MC4 are energized by connecting the Η I contact, and the 440V power is output from the second socket (40). If the voltage selection button (2 0) is accidentally changed to the position of 4 0 0V, the third relay (R Υ 3) will be energized. This can not only be connected through the RY3 normally closed position in the center of the drawing. Turn off the power of MC 3 and MC 4 (stop the voltage output), and at the same time, activate the buzzer (BZ) at the bottom of the fourth picture, which will generate an alarm sound and get the error warning. If the voltage selection button ( 2 0) The setting is correct, but if the 4 4 · 0 V start button (2 2) is touched by mistake, the voltage selection button (2 0) has cut off the 4 4 0V circuit, so there is no error voltage output. According to To form a power box voltage selector that can automatically identify and prevent operation errors. In addition, the present invention is provided with a current overload protection device, that is, a thermal
