Abstract
The utility model relates to a be applied to smog alarm device on distribution transformer, which comprises a housin, the casing surface is equipped with the inlet port, be equipped with gas impurity filter unit on the inlet port, just the unit that induced drafts has been set firmly to position department with the inlet port in the casing, still be equipped with smoke transducer and alarm that mutual electricity is connected in the casing.
Description
Technical field
This utility model relates to a kind of smoke alarm unit being applied on distribution transformer, and especially a kind of simple in construction, smog collecting effect is good, highly sensitive smoke alarm unit.
Background technology
The static electrical equipment of one that distribution transformer refers to convert alternating voltage and electric current according to the law of electromagnetic induction in distribution system and transmits AC energy.Some area, by the power transformer of less than 35 kilovolts (great majority be 10kV and following) electric pressures, is called " distribution transformer ", is called for short " distribution transforming ".The place of " distribution transforming " is installed with local, is electric substation.
There are the following problems in present electric substation, in the presence of a harsh environment, distribution transformer is highly prone to the impact of external environment condition, when such as smog and fire, if reported to the police not in time or monitoring, distribution transformer can be caused large effect, even can cause the irremediable accidents such as power transformation box blast.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of smoke alarm unit being applied on distribution transformer, and especially a kind of simple in construction, smog collecting effect is good, highly sensitive smoke alarm unit.
For solving above-mentioned technical problem, this utility model includes housing, described housing outer surface is provided with air inlet, described air inlet is provided with gaseous impurity filter element, with air inlet, just position is being installed with air draught unit in described housing, in described housing, is being additionally provided with the Smoke Sensor being electrically connected to each other and alarm.
After have employed said structure, owing to being provided with air inlet and air draught unit, so extraneous gas can be drawn in housing according to the function of air draught unit, play the technique effect gathering gas, and when in gas containing smog, Smoke Sensor and alarm in housing will detect smog the very first time, play the technique effect of warning, and contaminant filter unit is it is prevented that owing to the suction of induced-draught fan is excessive, and be absorbed in housing by the solid impurity that some are unnecessary, thus affect the normal operation of alarm and Smoke Sensor.
As further improvement of the utility model, described contaminant filter unit is the top cap net being fixedly arranged on air inlet, described top cap net includes four links, and described four links are respectively arranged in inner walls, and air inlet side is close to by top cap net.
After have employed said structure, filter element is drainage screen, it is possible to use whole air inlet is blocked by drainage screen, in the gas so entered by air inlet, as long as containing the solid impurity of bigger, all going out outside housing by filtered net filtration.
As further improvement of the utility model, described air draught unit is the induced-draught fan being arranged in housing, and described induced-draught fan includes fan and controls the control circuit that fan rotates, and described fan is towards being right against air inlet position.
After have employed said structure, the simple principle adopting induced-draught fan, in that context it may be convenient to play the technique effect of air draught, and fan is towards being right against air inlet position, also improves inspiratory effects.

Detailed description of the invention
As shown in Fig. 1 Fig. 2, this utility model includes housing 1, described housing outer surface is provided with air inlet 2, described air inlet 2 is provided with gaseous impurity filter element, with air inlet 2, just position is being installed with air draught unit in described housing, in described housing, is being additionally provided with the Smoke Sensor 3 and alarm 4 that are electrically connected to each other.Owing to being provided with air inlet 2 and air draught unit, so extraneous gas can be drawn in housing according to the function of air draught unit, play the technique effect gathering gas, and when in gas containing smog, Smoke Sensor and alarm in housing will detect smog the very first time, play the technique effect of warning, and contaminant filter unit is it is prevented that owing to the suction of induced-draught fan is excessive, and be absorbed in housing by the solid impurity that some are unnecessary, thus affect the normal operation of alarm and Smoke Sensor.
As in figure 2 it is shown, described contaminant filter unit is the top cap net 5 being fixedly arranged on air inlet, described top cap net 5 includes four links, and described four links are respectively arranged in inner walls, and air inlet side is close to by top cap net 5.Drainage screen 5 can be utilized to be blocked by whole air inlet, in the gas so entered by air inlet, as long as containing the solid impurity of bigger, all going out outside housing by filtered net filtration.
Described air draught unit is the induced-draught fan being arranged in housing, and described induced-draught fan includes fan 6 and controls the control circuit that fan rotates, and described fan 6 is towards being right against air inlet position.The simple principle adopting induced-draught fan, in that context it may be convenient to play the technique effect of air draught, and fan is towards being right against air inlet position, also improves inspiratory effects.
