Abstract
The utility model relates to an EMC case cabinet with ventilating system monitoring function, which comprises a case cabinet body, a 24V direct current power supply, a door switch, a relay and relative output contacts. The EMC case cabinet of the utility model is characterized in that a pneumatic switching device is connected in series and embedded in the case cabinet body; and the pneumatic switching device is composed of a filter main body, an inductive switch and a sheltering plate. The EMC case cabinet has advantages that two remarkable disadvantages existing in the application of the ordinary case cabinet for the controlling system can be effectively improved, and the case cabinet with higher performance rate is provided.
Description
(1) technical field:
The utility model belongs to a kind of case and cabinet, particularly a kind of EMC case and cabinet that has the ventilating system monitoring.
(2) background technology:
At present, there are two remarkable shortcomings in common control system with case and cabinet in application.The one,, even have the ventilation filter system, in use for some time, filter can be because the interior dust of filter cotton accumulates too much and stops up, and it is not smooth to cause ventilating, and temperature constantly raises in the cabinet, and the interior equipment of final cabinet can't normally move; In addition, if ventilation blower damages, also the problems referred to above can appear.The 2nd,, the demanding case and cabinet of IP degree of protection, sheet materials such as its side plate, door-plate, back plate all will mount sealing strip, and adopt the insulation spraying, make that the conductive capability between sheet material and cabinet body frame descends, and can't reach the EMC electromagnetic compatibility requirement of cabinet integral body.
(3) summary of the invention:
The purpose of this utility model is at the problems referred to above, designs a kind of EMC case and cabinet that has the ventilating system monitoring, to provide the more case and cabinet of high performance level.
The technical solution of the utility model: a kind of EMC case and cabinet that has the ventilating system monitoring, comprise case and cabinet body, 24V DC power supply, door switch, relay and relevant output contact, it is characterized in that: series connection embeds pneumatic switching device in the case and cabinet body; Said pneumatic switching device is made up of filter body, inductive switch and wind-blocking board, and filter and inductive switch are equipped with in cabinet air inlet place, and inductive switch places the upper end of filter body, and wind-blocking board places filter and inductive switch periphery.
On the above-mentioned said EMC case and cabinet that has a ventilating system monitoring screw that is connected usefulness with other cabinet body frames is housed, said screw has the copper alloy shell fragment of the beryllium copper material of the tooth that punctures.
The above-mentioned said copper alloy shell fragment that has the beryllium copper material of the tooth that punctures is straight flange perpendicular type or bent limit perpendicular type.
Operation principle of the present utility model is: the case and cabinet of this case makes pneumatic switch form an airtight connection work system with 24V DC power supply, door switch, relay and the series connection of relevant output contact by at the special pneumatic switch of the cabinet installed inside that the air-inlet window position is housed; Status signal of output after pneumatic switch is connected with door switch, the operating state of reflection ventilating system.Sense when having wind to pass through in the filter when the inductive switch of pneumatic switching device inside, pneumatic switch is sent out draughty signal to system; Can not sense when having wind to pass through in the filter when the inductive switch of pneumatic switching device inside, pneumatic switch is sent out the alarm signal of improper ventilation to system.
Superiority of the present utility model is: can improve common control system effectively with two remarkable shortcomings that case and cabinet exists in application, provide the more case and cabinet of high performance level.
(4) description of drawings:
Accompanying drawing 1 is the related a kind of structural representation that has the EMC case and cabinet of ventilating system monitoring of the utility model.
Accompanying drawing 2 is the related a kind of pneumatic switch operating circuit schematic diagram that has the EMC case and cabinet of ventilating system monitoring of the utility model.
Accompanying drawing 3 installs one of shell fragment shape commonly used of copper alloy shell fragment additional for the cabinet body frame of the related a kind of EMC case and cabinet that has a ventilating system monitoring of the utility model and the screw place between the sheet material.
Accompanying drawing 4 is two of the cabinet body frame of the related a kind of EMC case and cabinet that has a ventilating system monitoring of the utility model and shell fragment shape commonly used that the screw place between the sheet material installs the copper alloy shell fragment additional.
Wherein, 1. be the cabinet body, 2. be filter body, 3. be inductive switch, 4. be wind-blocking board; FK is pneumatic switch, and K is a door switch, and S is the 24V DC power supply, and R is a relay, and T is an output contact.
(5) embodiment:
Embodiment: a kind of EMC case and cabinet (seeing accompanying drawing 1,2) that has the ventilating system monitoring, comprise the case and cabinet body 1., 24V DC power supply S, door switch K, relay R and relevant output contact T, it is characterized in that: series connection embeds pneumatic switching device in the case and cabinet body; Said pneumatic switching device by filter body 2., 4. 3. inductive switch form with wind-blocking board, cabinet air inlet place be equipped with filter 2. with inductive switch 3., 3. inductive switch places filter body upper end 2., and wind-blocking board places filter 2. 3. peripheral with inductive switch.
On the above-mentioned said EMC case and cabinet that has a ventilating system monitoring screw (seeing accompanying drawing 3,4) that is connected usefulness with other cabinet body frames is housed, said screw has the copper alloy shell fragment of the beryllium copper material of the tooth that punctures.
The above-mentioned said copper alloy shell fragment (seeing accompanying drawing 3,4) that has the beryllium copper material of the tooth that punctures is straight flange perpendicular type or bent limit perpendicular type.
Claims (3)
