Abstract
The invention relates to an electrical equipment shield/cabinet cooling device, which has a good cooling effect and comprises a base. A power connector, a switch, a power indicating lamp, a screw base fuse, a temperature sensor with a temperature controlled switch, and fans are mounted on the base, wherein the power connector is serially connected with the switch, the power indicating lamp is connected with the power connector and the two ends of the switch in parallel, and the screw base fuse is serially connected with the temperature sensor with the temperature controlled switch and the fans and then is connected to the two ends of the power indicating lamp in parallel. By organically combining the fans, the temperature sensor with the temperature controlled switch, the power indicating lamp, the screw base fuse and the like, the fans are automatically started up according to the change of the internal temperature of a shield/cabinet, the flowing of air in the shield/screen is accelerated, the circulation of air in the shield/screen is effectively improved, the temperature of a direct-current rectifier shield/cabinet is decreased, the equipment damages caused by temperature rise are reduced, the power supply reliability is improved and the safe operation of equipment is guaranteed.
Description
Technical field
The present invention relates to a kind of power equipment, relate in particular to a kind of electric equipment screen, cabinet heat sink.
Background technology
Electric equipment screen, cabinet can be divided into high pressure, low pressure according to electric pressure; According to purposes can be divided into breaker cabinet, isolate cabinet, capacitor compensation cabinet, direct current cabinet, ac panel, protective device screen, communication screen, total control screen etc.; Most of screen, cabinet seal; It is comparatively tight that equipment in a lot of screens, the cabinet is installed, and the heat that equipment distributes gathers easily, and the inspection personnel can feel that temperature can be very high in the screen when especially opening checkout facility summer; Cause device temperature to raise easily, influence useful life and security reliability.The cooling way majority that adopts at present is to carry out the free convection cooling at screen, cabinet top drilling, and some installs fan additional and long-term the unlatching lowered the temperature, but effect is all bad.
Summary of the invention
The electric equipment screen, the cabinet heat sink that the purpose of this invention is to provide a kind of good cooling effect.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of electric equipment screen, cabinet heat sink comprise base, it is characterized in that: temperature sensor and fan that power connection, switch, power supply indicator, screw type fuse, band temperature detect switch (TDS) are installed on the base; Power connection is connected with switch, and power supply indicator is parallel to power connection and switch ends, and screw type fuse and temperature sensor, the fan of band temperature detect switch (TDS) are parallel to the two ends of power supply indicator after connecting again.
According to described electric equipment screen, cabinet heat sink, it is characterized in that: three said fans are installed on the said base, and three fans are the parallel connection relation.
The present invention is through organically combining fan, the temperature sensor of being with temperature detect switch (TDS), power supply indicator, screw type fuse etc.; Fan is opened in variation according to screen, in-cabinet temperature automatically, quickens air flow in screen, the cabinet, effectively improves the air circulation in screen, the cabinet; Reduce the temperature of direct current rectifier cubice, cabinet; The device damage that minimizing causes because of temperature rise improves power supply reliability, guarantees equipment safety operation.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is further described:
A kind of electric equipment screen, cabinet heat sink like Fig. 1, Fig. 2, shown in Figure 3, comprise base 7, and the temperature sensor 5 and the fan 6 of power connection 1, switch 2, power supply indicator 3, screw type fuse 4, band temperature detect switch (TDS) is installed on the base 7; Power connection 1 is connected with switch 2, and power supply indicator 3 is parallel to power connection 1 and switch 2 two ends, screw type fuse 4 and the two ends that are parallel to power supply indicator 3 after temperature sensor 5, the fan 6 of being with temperature detect switch (TDS) are connected again.In the present embodiment, 6, three fans of three fans 6 being installed on the base 7 is the parallel connection relation.
The present invention is made up of temperature sensor, fan and the base of power connection, power supply indicator, switch, screw type fuse, band temperature detect switch (TDS), and base is installed on screen top (referring to Fig. 4) through independent support, and easy access is safeguarded; Can adopt storage battery inversion out-put supply when power supply has DC power supply in switchgear house, improve reliability; The fan number adopts three formulas that can form remarkable air-flow; The starting fan mode adopts and can initiatively arrange the temperature detect switch (TDS) of fan start and stop to start formula according to ambient temperature.
Make when of the present invention, three fans are installed in the base centre position side by side, the temperature sensor of band temperature detect switch (TDS) is installed in the centre position of chassis left side, switch, power supply indicator, screw type fuse are installed in the position, the lower left corner of base.Electric connecting relation between each part is: power connection is connected with switch; Power supply indicator is parallel to its two ends, screw type fuse and the two ends that are parallel to power supply indicator after the fans of the temperature sensor of band temperature detect switch (TDS), the parallel connection of three fans are connected again.
In the present invention, fan plays the effect of strengthening air circulation in electric equipment screen, the cabinet, reducing screen, in-cabinet temperature; The temperature sensor of band temperature detect switch (TDS) works the temperature upper limit system of reaching with regard to automatic processing circuit, starts the purpose that fan is lowered the temperature; Power supply indicator is used for fan and plays suggesting effect in working order the time; Screw type fuse shields.
When needing the present invention to work, set temperature upper limit earlier, when the temperature in temperature sensor records screen, cabinet reaches higher limit; Automatically temperature detect switch (TDS) closes; Start fan and lower the temperature, when temperature is lower than higher limit once more, the temperature detect switch (TDS) automatic disconnection; Thereby realize the automatic control of fan, reached the purpose of energy-conservation cooling.
