Description

Technical Field

[0001] The utility model relates to the technical field of factory lighting, and particularly designs a centralized control type electrical switch. Background Technique

[0002] At present, due to the large area of the factory area, scattered production workshops and numerous equipment in large factories, the lighting system needs to be arranged nearby according to the distribution of the on-site power room. Now the degree of factory automation is high and there are few on-site employees, so it is unrealistic to turn on and off the lighting manually in a scattered manner. Using cables to connect all workshop lighting to a unified control circuit has a long line and a large investment. The long line is also limited by voltage drop, and it is difficult to find the fault point when problems occur. A large number of decentralized installation timing controllers and light sensor controllers are required, and there are problems such as inconsistent timing time and light sensor control time that often need to be adjusted, and the failure rate is relatively high, resulting in energy waste.

[0003] In the prior art, there are three main lighting implementation methods in factories:

[0004] I. Local control: Switches are set locally for each group of lamps for on-off control. The circuit is saved, but all control operations are manual, time-consuming and laborious. To turn on or off the lighting of the entire workshop, it is almost necessary to run through the whole building.

[0005] II. Workshop centralized control: A lighting control box is set at the entrance and exit of the workshop, and the lighting of the whole building is controlled through the switches in the box. Centralized operation is relatively convenient, but the line is too long, which is prone to problems such as terminal short circuit and inability to protect, and it is impossible to observe whether the lighting lamps are turned on.

[0006] III. Lighting intelligent control system control: It has intelligent control, powerful functions, advanced energy saving, but there are problems such as a large one-time investment and the need to install control modules in the workshop lighting box. Content of the Utility Model

[0007] In view of this, the utility model provides a centralized control type electrical switch, which can realize dual control on the control panel and distribution box of the factory, and simply and economically solve the problems of inconvenient operation of decentralized control and the resulting electric energy waste.

[0009] Furthermore, the contact switch 22 is divided into a contact point switch 221, a normally closed contact 222, and a normally open contact 223.

The normally closed contact 222 is connected to the input end of the indicator light 12, and the normally open contact 223 is connected to a corresponding third switch assembly 3.

[0010] Furthermore, when the first switch 11 is in the open / closed state, the contact point switch 221 is located at the normally closed contact 222, and the indicator light 12 lights up. The input end of the power supply is connected to the normally closed contact 222 of the contact point switch 221, then connected in series with the indicator light 12, and finally connected to the output end of the power supply to form a loop.

[0011] Furthermore, when the first switch 11 is in the closed state, the contact point switch 221 is located at the normally open contact 223, and the indicator light 12 is off. The loop where the first switch 11 is located is connected in parallel with the loop where the contact point switch 221 is located.

[0012] Furthermore, the loop where the first switch 11 is located is composed of a first switch 11 connected in series with a relay 21 corresponding to a second switch assembly 2.

[0013] Furthermore, the loop where the contact point switch 221 is located is composed of a contact point switch 221 connected in series with a corresponding third switch assembly 3 through the normally open contact 223.

[0014] Furthermore, the third switch assembly 3 includes a contactor 31 and a second switch 32. The input end of the contactor 31 is connected to the normally open contact 223, and the output end of the contactor 31 is connected to the power supply.

[0015] Furthermore, the second switch 32 is connected in series with a plurality of light-emitting components.

[0016] Furthermore, the first switch assembly 1 and the second switch assembly 2 are both arranged on the control panel, and the third switch assembly 3 is arranged in the distribution box. The total circuit can be controlled through the first switch assembly 1 on the control panel, and the light-emitting components in a small range can be controlled in the distribution box when the total circuit is turned on. In this way, through the dual switches of the control panel and the distribution box, both centralized control and decentralized control in a small range can be achieved.
