Construction site power utilization period and overload controlling method and power distribution device

Abstract

The invention discloses a construction site power utilization period and overload controlling method and a power distribution device. The method comprises the steps that a general distribution box is arranged at a power source line incoming position and is provided with three output paths, the first path is a dormitory power output path, the second path is a construction power output path, and the third path is a safety power output path, wherein the dormitory power output path and the construction power output path are both provided with a time switch; the power utilization periods of dormitories and construction are controlled respectively through the time switches; in a work period, dormitory power supply is automatically cut off, and power is only supplied to construction; in a non-work period, construction power supply is automatically cut off, and power is only supplied to the dormitories; the normal power supply to construction lighting and a safety alarming system is guaranteed through the safety power output path. According to the construction site power utilization period and overload controlling method and the power distribution device, through the simple improvement on the power distribution device on a construction site, the power utilization safety problem of the construction site is well solved; although the initial investment is slightly larger than that of a traditional power distribution scheme, the power utilization cost can be greatly reduced. Meanwhile, the power utilization normative performance and safety of the construction site are improved.

Description

technical field [0001] The invention relates to a construction site power consumption period and overload control method and a power distribution device, belonging to the technical field of construction site power distribution. Background technique [0002] In building construction, the management of power consumption is not standardized, and the construction power and domestic power consumption in many construction sites are usually not set separately. Workers in some dormitories often forget to turn off the power when they leave the dormitory. In some dormitories, the lights are always on. What is more dangerous is that some people are using electric stoves to boil water or cook. If there is an emergency, they forget to turn off the electric stove, which is likely to cause electrical safety accidents. . Although the construction site also has strict rules and regulations, it is strictly forbidden to connect the power cord without permission in the dormitory of the constru...

Problems solved by technology

Workers in some dormitories often forget to turn off the power when they leave the dormitory. In some dormitories, the lights are always on. What is more dangerous is that some people are using electric stoves to boil water or cook. If there is an emergency, they forget to turn off the electric stove, which is likely to cause electrical safety accidents.

Although the construction site also has strict rules and regulations, it is strictly forbidden to connect the power cord without permission in the dormitory of the construction site living area, and it is strictly forbidden to use high-power electrical appliances such as electric stoves and induction cookers without permission. Difficult to manage, overloaded electricity often causes tripping of circuit breakers and burnout of switches, overcurrent of lines causes electrical fires and other electrical safety accidents
