In the case of being below certain city Liang Ge stations off-peak period, using rays safety detection apparatus of the present utility model and method meter
Calculate the power consumption of rays safety detection apparatus after improving.
X-ray security inspection machine is the GJ-XS6550 type X-ray security inspection machines of the high crystalline substance image science and technology production in Shanghai, motor specified
Power is 800VA, transmits tape speed 0.2m/s, and the handling capacity of screening machine is 32 people/min.
VA is the apparent energy unit of electrical appliance, because V is voltage unit, A is current unit, according to P=UI, i.e. VA is
Power unit.W is also power unit, represents the reality/rated power of electrical appliance.Here rated power be 800VA, i.e., specified work(
Rate is 800W.
The power consumption for calculating one hour of equipment is：800/1000kw × 1h=0.8kw h.
The process (i.e. the moment of electric motor starting) of start compares expense electricity.Electric motor starting electric current is rated current in general
5 to 7 times.Power is corresponding namely 5 to 7 times.So the rated power that startup power consumption is approximately equal to motor is taken advantage of in 5 to 7 times
Motor starting time.When motor is little, power is big, voltage is high, motor performance is good, power of starting shooting is 5 times of rated power,
Then 5 times rated power are taken here, i.e. electric motor starting power consumption is：
W=Pt=0.8kw h × 5 × (1/3600)=0.001111kw h
W units are kw h, and P units are kw, and t units are h.
After improvement, rays safety detection apparatus power consumption is by electric motor starting power consumption and equipment operation power consumption summation, according to certain city station
1 hour off-peak period passenger flow situation calculates one hour power consumption condition, is compared with one hour power consumption condition of original equipment.By
It is to be plugged into using regular public traffic in track traffic trip majority, especially suburban line, regular public traffic are plugged into and can produce passenger flow
Compare the situation of concentration in a certain period, therefore by station passenger flow by batch division.
Assuming public transport to plug into, to need the passenger for changing to track traffic be ten people.
A stations statistics 10:00-11:The passenger flow that enters the station when 00 is 44, and outbound passenger flow is 65.
Due to only needing to take into account that standee flows, the time required for 44 people are entered the station is：
44/32=1.375min=0.0229h.
Public transport is plugged into a collection of 10 people, i.e. 44/10=4.4, about 5 batches.
The present embodiment equipment power consumption within this time period is：
5 × 0.001111kw h+0.0229h × 0.8kw=0.023875kw h ＜ 0.8kw h
B stations statistics 10:00-11:The passenger flow that enters the station when 00 is 148.
The time required to entering the station it is：
148/32=4.625min=0.077h
148/10=14.8, about 15 batches.
The present embodiment equipment power consumption within this time period is：
15 × 0.001111kw h+0.077h × 0.8kw=0.0783kw h ＜ 0.8kw h
The suburban line station of off-peak period, using the safety check apparatus after improving, is to reach the effect for saving electric energy
, and during the effect of motor time-out, X-ray emitter is also out of service, not only can extend the service life of ray emitter,
Be also possible to prevent security staff cross long-time in the range of actinism.
