Unit resident normal/ emergency power supply switch board and its power supply automatic converting device

Abstract

A home power cabinet panel is provided to supply a supply voltage in a normal status and an emergency power in an abnormal status by including a power switching unit in the home power cabinet panel. A home power cabinet panel comprises a main circuit breaker(102) for cutting off a supply voltage when generating an over-current or a leakage current by detecting the status of the supply voltage; a plurality of sub circuit breakers(204,206,208) connected to an output terminal of the main circuit breaker with an electric wire and which is branched from the electric wire for supplying the supply voltage to a general electric load and cuts off the power when generating an over-current or a leakage current at the electric load; and an auto power switching unit(220) for supplying an emergency power through an emergency wire when not receiving the supply voltage and supplying the supply voltage through the emergency wire when receiving again the supply voltage by cutting the emergency power.

Description

technical field [0001] The invention relates to a common / emergency power switchboard for unit households and its common / emergency power supply circuit for unit households, especially to important equipment such as household automatic equipment, gas alarms, emergency lighting, electronic fire extinguishers, and heating and cooling equipment. Common / emergency power switchboards for units and households that supply common power in normal conditions and emergency power in emergency periods and their automatic conversion devices. Background technique [0002] The switchboards of general unit households are set up according to unit households in buildings such as apartments, villas, single houses, public buildings, and office buildings, and play the role of redistributing the common power supply supplied from the outside to each electrical load to prevent leakage or in- The function of cutting off the power supply in case of overload to prevent the occurrence of fire or damage to ...

AI Technical Summary

Problems solved by technology

[0011] The common power supply and emergency power supply wiring of the above-mentioned unit households has a structure of separately arranging the common power supply and the emergency power supply. Unable to use emergency power

[0012] In addition, in order to supply emergency power during a power outage, pipes are vertically laid between the upper and lower floors of the unit residents, so the noise between the floors transmitted through the pipes will cause many problems such as affecting personal life or living inconvenience caused by noise.

[0013] In the case of using home automation equipment, prepare a backup battery so that it can work even in the event of a power outage, but if there is no backup battery for home automation equipment or the backup battery cannot be used due to battery fluid leakage due to long-term non-use In this situation, it is impossible to start the household automatic equipment, so there is the inconvenience of not being able to enter and exit

In addition, when using home automatic equipment, if there is a power failure for a long time, the battery life is limited, so there is a problem that the home automatic equipment cannot work when the battery life ends, and the door lock cannot work and cannot enter the house when returning from going out. Unable to achieve remote control

[0014] In addition, electronic fire extinguishers cannot be used because they cannot be supplied with power during a power outage, and if a fire breaks out in an apartment building, the electronic fire extinguishers will not work, and they will suffer huge losses.

[0015] In addition, when the power is cut off in cold weather with low temperature, the heater cannot be turned on, so there are many inconveniences such as frost cracking or cold exposure.

[0016] In addition, in the case of household automatic equipment, the volume of the housing of the household automatic equipment will increase because of the need to prepare a backup battery. When constructing the cement for installing the wall of the housing, it is impossible to fill in the cement equivalent to the volume of the housing. Into the cement of the shell size, so there is a possibility of cracking
