Example 1:
as shown in fig. 1, 2 and 3, in the distribution room with the fire alarm described in this embodiment, a distribution cabinet 2 is disposed in the distribution room 1, and the distribution cabinets 2 are independently disposed in the distribution room 1; the power distribution cabinet 2 is provided with a left side wall 3, a right side wall 3 and a bottom plate 4, a temperature probe 5 and a temperature controller 6 are arranged in the power distribution cabinet 2, and a signal of the temperature probe 5 is input into the temperature controller 6, and the power distribution cabinet is characterized in that a coil chamber 8 formed by a vertical partition plate 7 and one side wall 3 and an air inlet chamber 9 formed by a transverse partition plate 18 and the bottom plate 4 are arranged in the power distribution cabinet 2; it should be noted that: the front surfaces of the coil chamber 8 and the air inlet chamber 9 can be provided with panels for sealing, or can be sealed by a cabinet door of the power distribution cabinet 2 without being provided; a fan 10 controlled by the temperature controller 6 to work is arranged on the side wall 3 opposite to the coil chamber 8; the air inlet 28 of the coil chamber 8 is positioned in the air inlet chamber 9; a cooling coil 11 is arranged in the coil chamber 8; an overflow hole 12 is arranged on the vertical clapboard 7; an air inlet pipe 14 is arranged on the bottom plate 4; a general cooling water supply pipe 15 and a cooling water return pipe 16 are arranged at the lower part of the power distribution cabinet 2, and a water supply pump 17 is arranged on the cooling water supply pipe 15; the inlet of the cooling coil 11 in each power distribution cabinet 2 is connected with a cooling water supply pipe 15 through a connecting pipe 19, the outlet of the cooling coil is connected with a cooling water return pipe 16 through a connecting pipe 19, and the connecting pipe 19 penetrates through an air inlet pipe 14 at the bottom of the corresponding power distribution cabinet 2; the cooling water supply pipe 15 and the cooling water return pipe 16 are respectively communicated with a cooling water supply end 20, wherein the cooling water supply end 20 can be a circulating water cooler for cooling water by a refrigerant, but the structure of the circulating water cooler is relatively complex, and since the power distribution room is located outdoors in many cases and does not have the condition of configuring the circulating water cooler, the best scheme is that the cooling water supply end 20 is an underground water well, and the water supply pump 17 is a submersible pump located in the underground water well; well water with lower temperature is used as cooling water, so that the cooling effect can be ensured, and the well is easy to dig and take water in the field, thereby being convenient to implement; the ceiling in the power distribution room 1 is provided with a fire alarm 29, the fire alarm 29 is arranged on one ceiling (located at the center) in the power distribution room 1, and the fire alarms 29 can also be uniformly distributed; the fire alarm 29 preferably adopts a HZBJ101 type fire alarm manufactured by Ningbo High New Zealand sky-vision photoelectric Co., Ltd, and can also be purchased from the market, such as a GSM01 type electrical fire monitor of the Shanghai North Red energy science and technology Co., Ltd, and the existing patent technology can also be used, such as a fire alarm (200910163698.8) and a fire alarm (200910168090.4).
Wherein, the bottom of the power distribution cabinet 2 can be provided with support legs, and the cooling water supply pipe and the cooling water return pipe are arranged on the ground, but preferably, the lower part of the ground of the power distribution room 1 is provided with a groove 21; a cover plate 22 is arranged at the top of the groove 21, and an opening 23 for the air inlet pipe 14 to pass through is arranged at the part of the cover plate 22, which is opposite to each power distribution cabinet 2; the cooling water supply pipe 15 and the cooling water return pipe 16 are positioned in the groove 21; with the structure, after cooling water circulates, the temperature of the grooves 21 is lower, air in the grooves 21 enters the source of each power distribution cabinet 2, the temperature of the air source is low, and the cooling effect on the power distribution cabinets 2 is better;
according to the power distribution cabinet, after cooling water circulates, the temperature in the coil pipe chamber 8 is reduced, low-temperature air in the coil pipe chamber 8 can overflow through the overflow hole 12 to cool the power distribution cabinet, on one hand, the temperature can be reduced, on the other hand, the temperature rising speed can be reduced, so that the power distribution cabinet is in a balanced state with slow temperature rising, and meanwhile, the coil pipe chamber 8, the air inlet chamber 9 and the groove 21 are communicated together, and the temperature is lower; once the temperature in the power distribution cabinet is too high, so that the fan 10 works, cold air in the coil pipe chamber 8 is pumped outwards through the overflow hole 12, low-temperature air in the air inlet chamber 9 and the groove 21 is pumped into the coil pipe chamber 8 for cooling, hot air is pumped out, cold air is pumped in, and therefore the heat dissipation effect is effectively improved. On the other hand, when the fire alarm 29 detects a fire hazard, the power distribution cabinet can give an alarm to prompt people to carry out fire protection.
Example 2:
as shown in fig. 4, in the electrical distribution room with a fire alarm described in the present embodiment, the cooling coil 11 has a plurality of parallel horizontal sections 24; coil fixing blocks 25 are arranged between the horizontal section 24 and the side wall 3 of the cooling coil 11 and between the horizontal section 24 and the vertical partition plate 7; the region corresponding to the horizontal section 24 of each cooling coil 11 on the vertical partition plate 7 is provided with a trapezoidal part 26 protruding to the side; the cooling coil 11 is located in the trapezoidal portion 26, and the overflow groove 13 is provided on the inclined top surface 27 of the trapezoidal portion 26.
With the structure, when the fan 10 works and cold air in the coil chamber 8 is pumped out through the overflow groove 13, the supplemented air source is fully contacted with the horizontal section of the horizontal section 24 of the cooling coil 11, thereby ensuring the heat exchange effect; because the air must pass through the three channels formed by the curved surfaces and the flat surfaces on the left and right sides and obliquely below the cooling coil 11 to exit from the overflow chute 13.
In this embodiment, it is preferable that the width of the overflow groove 13 is larger toward the upper portion, and the width of the overflow groove 13 is smaller toward the lower portion, so that when the fan 10 is in operation, all the overflow grooves 13 can uniformly draw out cold air, and the problem that only the overflow groove 13 on the lower portion blows out air to disable the cooling coil 11 on the upper portion is avoided.
Example 3
This embodiment describes a method for monitoring a distribution room with a fire alarm as described in embodiment 1, which uses a temperature controller 6 to control a fan 10 to cool down and a water pump controller to control a water supply pump 17 to circulate cooling water in each distribution room 2, and is characterized in that the temperature controller 6 controls a process including:
when T is larger than or equal to TH, starting the fan 10, and stopping the fan 10 until T is smaller than TL;
when T is less than TH, starting a temperature-rising monitoring mode;
the warming monitoring mode includes:
measuring V, when V < VS; resetting the SA and returning to the upper-level program;
when V is larger than or equal to VS, starting the fan 10, stopping the fan 10 after TA time, then measuring V again, when V is smaller than VS, returning to the previous-stage program, otherwise, marking SA as 1;
wherein: t is the real-time temperature inside the switch board 2;
TH is a preset value and represents the alarm high temperature of the power distribution cabinet 2;
TL is a preset value and represents the safe temperature of the power distribution cabinet 2;
v is the temperature rise rate in the power distribution cabinet 2;
VS is a preset value and represents the safe temperature rise speed of the power distribution cabinet 2;
the measurement V is the temperature rise speed of the unit time, the total temperature rise is divided by the time, and the measurement calculation can be carried out after waiting for 1-2 minutes;
a fire alarm 29 is arranged on the ceiling in the power distribution room 1 for fire monitoring;
the water pump controller controls the water supply pump 17 to work periodically; e.g., once an hour for 5 minutes each;
the principle of the temperature monitoring method is as follows:
the water supply pump 17 works periodically, the cooling coil 11 is cooled periodically (can work once per hour, and lasts for five minutes each time), the temperature of the coil chamber 8 is relatively low, and the temperature and the heating speed in the power distribution cabinet are controlled by the overflow of cold air;
when the accident condition T is higher, namely when T is more than or equal to TH, the fan 10 works until the temperature in the power distribution cabinet 2 is reduced to a safety value TL; and when T < TH, start the monitoring mode of intensification, when the programming rate in switch board 2 is greater than we thought comparatively suitable safe programming rate VS, also start fan 10 work and cool down for a while, because there is the overflow of the cold air of coil room 8 according to the theory, the programming rate in the switch board should not exceed the safety range, it explains that the cooling efficiency of coil room 8 is low to have surpassed, or certain component has generated heat great, for preventing too fast intensification, start fan 10 with the cooling, make whole switch board all be unlikely to the high temperature like this. The more frequently the water supply pump 17 is periodically operated, the more the cooling efficiency of the coil chamber 8 can be ensured, but the more the energy consumption will be increased.
The temperature controller 6 control method can be executed with reference to fig. 5 and 6, but is not limited to the modes of fig. 5 and 6.
In the method, the value of the SA can be associated with a warning lamp outside the power distribution cabinet, and the lamp can be turned on to warn when the temperature is quickly raised and cannot be controlled by the fan.
Example 4
This embodiment describes a monitoring method of the electricity distribution room with the fire alarm described in the above embodiment 1, and unlike embodiment 3, the water pump controller is more intelligent, and it does not simply control the water supply pump 17 to operate periodically, but the control process of the water pump controller on the water supply pump 17 includes:
when the number of the power distribution cabinets 2 with the SA of 1 accounts for a certain proportion (such as one third) of the total number, the water supply pump 17 is started to work and lasts for a time TB, and the higher the proportion of the number of the power distribution cabinets 2 with the SA of 1 accounts for the total number is, the longer the time TB is;
when the number of the power distribution cabinets 2 with the SA of 1 is higher, it indicates that the cooling coils 11 in the power distribution cabinets 2 are in failure, and therefore the water supply pump 17 needs to be started, and when the number of the power distribution cabinets 2 with the SA of 1 is higher, it indicates that more cooling coils 11 in the power distribution cabinets 2 are in failure, and therefore the working time of the water supply pump 17 needs to be prolonged, so as to ensure the cooling effect of the cooling coils 11 in all the power distribution cabinets 2;
can be as follows: when the ratio reaches one third, TB is 5 minutes; when the ratio reaches one-half, TB is 7 minutes; when the proportion reaches three quarters, the TB is 10 minutes; when the ratio reached one, TB was 15 minutes.
Example 5
This embodiment describes a method of monitoring a distribution room having a fire alarm as described in embodiment 1 above, and differs from embodiment 3 in that the fan 10 is operated while the water supply pump 17 is operated;
in embodiment 3, when the pump 17 is supplied, the fan 10 is operated or stopped according to the original control method; this embodiment is rather than the difference is at the working time of working pump 17, fan 10 also follows work, because working pump 17 during operation, cooling coil 11's cooling is effectual, and the wind regime is colder, and fan 10 also follows work regardless of the temperature and the programming rate in the switch board of oneself, can make temperature status safer in the switch board.
The method of this embodiment is also suitable for embodiment 4, and the control flow can refer to fig. 7.
The methods described in examples 3-5 are equally applicable to the structure of example 2.

In this monitoring method of a distribution room having a fire alarm, when a fire is detected by the fire alarm 29, the entire distribution room 1 is powered off, and the water pump 17 is turned on to extinguish the fire using the fire extinguishing nozzle 30 provided in the distribution room 1. This modification of the monitoring method can also be applied to examples 3 to 5.
In the field, when the fire alarm detected there is the conflagration hidden danger, the groundwater well provided the water source of putting out a fire, made the fire extinguishing possible, if do not have this scheme's own groundwater well, the water intaking is also very difficult because of the difficulty, more can't put out a fire, therefore this embodiment security is better.
