Description

[Detailed Description of the Invention] Technical Field The present invention uses a generator power source in addition to a commercial power source to
The present invention relates to a generator power source starting device that automatically or dynamically starts a generator power source when a commercial power source is stopped, thereby constantly supplying power to a load.

BACKGROUND ART Generally, when supplying power to a load, a commercial power source is used. However, when the commercial power supply fails, power is no longer supplied to the load and the load stops. In cases where it would be a problem if the load stops, use the commercial power supply. Are known.

However, the conventional generator power supply automatic starting device has a complicated circuit layout, a large number of parts, and a valence of 1:'f1.

In addition, handling and maintenance inspections are cumbersome and time consuming, and malfunctions may occur.

The first object of the present invention is to provide a circuit for an external power source while supplying power to a load from one of the commercial power source and the generator power source.
The purpose is to provide a circuit layout that allows maintenance and inspection of parts.

A second object of the present invention is to provide a circuit arrangement that allows automatic and manual switching between commercial power and generator power.

A third object of the present invention is to provide a circuit arrangement that allows automatic and manual control over the method of starting and stopping the generator power supply.

Structure of the Invention In order to achieve the above object, the present invention connects the load to a commercial power source through a first main switch, and to a generator power source through a second switch. Means for detecting a certain percentage of the power supply voltage is connected to the commercial power supply and the generator power supply, respectively. Regarding the method of starting and stopping (control) the generator power supply,
Press one step of a changeover switch or the like to determine (select) automatic control or r-dynamic control. If this is automatic, the voltage detection means of the commercial power supply
Starting or stopping of the generator power supply is controlled in response to the detection of the generator. If it is manual, it has means such as a push button switch to control starting or stopping of the generator power supply. Whether the power source connected to the negative power source 1 is a commercial power source or a generator is automatically selected, but a means such as a changeover switch is provided to manually determine whether the power source is to be connected to a commercial power source or a generator. If this is automatic, it has first main switch control means such as a relay that controls the if main switch to close or open in response to the voltage detection means of the commercial power source detecting the presence or absence of the voltage. The second main switch control means, such as a relay, controls the second main switch to open or close in response to the commercial power supply voltage detection means detecting whether or not the voltage is present. If the means for selecting the switching of the power source is manual, means such as a changeover switch for determining which of the first main switch and the second main switch should be closed is turned on. It is also divided into IJJ conversion means for the commercial power source and generator power source, and means for starting and stopping the generator power source.

Furthermore, the first stage of switching between the commercial power source and the generator power source is divided into automatic and manual switching means. The method for starting and stopping the generator power supply is divided into automatic and manual methods.

In this way, when the commercial power supply +3 is connected and supplied to the load connected via the power outlet (outlet) 22.23, if the commercial power supply +3 fails, the generator power supply 14
is connected to Consef) 22.23. That is, when the commercial power supply 13 loses power, the voltage relay 39 becomes de-energized.

Then, the first contact 19a of the voltage relay 39 is turned off, the third contact 39b is turned on, and the first contact 39C is turned on to return to normal operation (the state shown in FIG. 3.5). When the first contact: 19c is turned on, the voltage relay 42 of the generator power supply is de-energized,
Since the first point 242 is A7-shaped, the starting relay 47 and one of the delay relays 52 form a closed circuit with the operating power source 59, and the starting relay 47 is energized first. . When the start relay 47 is energized, the contact 47I of the start circuit 50 of the engine start circuit 4H in FIG.

Then, when the second contact 52b is turned on, one side 52 of the delay relay is energized, and then the other side 53 of the delay relay is activated after a predetermined time delay, and after a predetermined time, the contact 53a is turned off. One of the delay relays 52 is de-energized. At this time, the circuit of the starting relay 47 and the delay relays 52 and 53 is such that the starting relay 47 is 1 once.
It returns to the initial state that was excited. This causes the circuits of start relay 47 and delay relays 52, 53 to repeat the start operation of engine start circuit 49 as described above. In this manner, the engine starting control of the generator power source 14 is repeated until the generator power source 14 normally generates electricity and a predetermined voltage is generated at the voltage relay 42. Generator mine source 14

In this way, the negative burr connected via the power source 22 etc. receives power from the commercial power source 13 or the generator power source 14 which is automatically stopped 11 and started depending on the presence or absence of the commercial power source 1. Can be supplied.

When the automatic/closing switching means 44 for starting/stopping the generator power supply is switched to the manual 44a side, the generator mine source 14 is turned on by the generator power supply ON means 45 or OFF means 46 regardless of the presence or absence of the commercial power supply I3. It can be started or stopped. Therefore, there is an advantage that the generator power source 14 and its related circuits can be maintained and inspected while the commercial power source I3 is connected to the load. This is the automatic/manual switch F for switching the power supply between the commercial power supply 13 and the generator power supply 14.
This also depends on the fact that the means for selecting between k3:+, the commercial power source I:l, and the generator mine source 14 is irrelevant where it is located.

Also, when the automatic/manual reno change means 33 for electric wire reno change regarding the commercial power source 13 and the generator power source 14 is switched to the manual 33a side,
Whether power is to be obtained from a commercial source or a generator can be determined based on the position of the selection means 31, and the starting/stopping power method regarding the generator power source 44.45
．． 4 (Able to perform maintenance and inspection of the commercial power supply 13 and related circuits, unrelated to i).

This can be done with the generator mine source 14 connected to the load.

In this way, maintenance and inspection of this device, power supply, and load can be easily performed.
It can be done easily.

According to the present invention, as shown in FIG.
The switching means 31 and 33 regarding the power source can be arranged separately. The automatic/manual switching means 440 1A4a, which controls the starting/stopping method of the generator power source, can be provided with an on/off means 45 or 4[] for the starting/stopping method that flashes on the generator power source. Also, automatic/manual switching means 3 for switching regarding power supply.
Place the power supply reno replacement means 3I on the manual 33a side of 3+:
'i' can. That is, the startup board I2 is divided into quadrants 1 to ■, and the means for starting and stopping methods and power supply switching, for example, are placed in the I, II, and I, ■, quadrants, and the means for switching the power source are placed in the iYj, L, ■, and ■ quadrants, respectively. Automatic side and! ■, ■There is an effect that people Y can be placed on the moving side in the limited quadrant.
