Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] The explosion-proof light-sensing lighting control device of the present invention is based on the following three considerations: first, the particularity of the working environment of the oil drilling rig. The working environment of drilling rigs is very complicated. In extremely hot (desert) and extremely cold (polar) environments, high requirements are placed on the adaptability of equipment; Frequent movement, etc.), making later product maintenance and tracking services difficult, so the product must be reliable and durable, but also meet the relevant requirements of oil drilling rig electrical. This special requirement just causes the light sensing technology in urban lighting to be unable to be applied to the oil drilling rig, so the present invention introduces the explosion-proof requirement at first in the technical solution...

Abstract

The invention discloses an explosion-proof light-induced lighting control device. A circuit breaker is arranged on a three-phase output line of a power supply, an intermediate relay KA contact and a second photosensor contact are respectively connected with a B phase line at an output end of the circuit breaker, the intermediate relay KA contact is connected with a self-locking button, an output end of the self-locking button is connected with an intermediate relay KM contact, a self-resetting button and a first photosensor contact simultaneously, and output ends of the intermediate relay KM contact, the self-resetting button and the first photosensor contact are connected with an intermediate relay KM coil simultaneously; the second photosensor contact is connected with an intermediate relay KA coil; an output end of the intermediate relay KM coil and an output end of the intermediate relay KA coil are connected with a zero line of the power supply simultaneously; and a second circuit breaker is installed on a working line which is connected with the power supply. By the aid of the device, the natural light is used to the maximum extent, the electric energy consumption is reduced, and the cost is reduced for users.

Description

technical field [0001] The invention belongs to the technical field of electromechanical control, and relates to an explosion-proof light-sensing lighting control device. Background technique [0002] At present, there is a lot of subjective randomness in the start and stop of lighting devices on oil drilling rigs. As oil drilling rigs, especially offshore platforms, are increasingly demanding on lighting, for example, many offshore platform users require that the lighting range be seamlessly connected, otherwise there will be safety hazards, and the demand for lighting on oil drilling rigs continues to increase, resulting in rising electricity costs. [0003] In the existing lighting circuit control device, due to the particularity of geographical time difference, the start-stop time of the lighting device on the oil drilling rig cannot be well controlled, which leads to a certain degree of subjective arbitrariness in the judgment of control.
