Problems solved by technology
[0002] At present, in the Internet age, people prefer to add communication systems to various devices to facilitate real-time remote observation of device status and information to prevent device damage; communication is inseparable from communication antennas that enable signal transmission and reception; so far in There are few cases of setting communication equipment on high-voltage power distribution cabinets or distribution boxes, because there is an unavoidable factor, that is, the electric field of the power distribution cabinet will affect the transmission parameters, gain and omnidirectionality of the antenna; Working in a strong electric field requires the antenna itself to have better performance in direction; in addition, due to design defects in the current power distribution cabinet, the heat dissipation performance is often poor, so a design that can automatically adjust the temperature and heat dissipation, And the power distribution cabinet with communication function is needed by the market

Embodiment 2
[0035] In the multi-data monitoring power distribution cabinet described in this embodiment, an isolation ring is further provided on the oval PCB. In the multi-data monitoring power distribution cabinet described in this embodiment, the number of hollow hole units on each bridge arm is four. In the multi-data monitoring power distribution cabinet described in this embodiment, the free end of the first vibrator arm is a wedge-shaped angle. In the multi-data monitoring power distribution cabinet described in this embodiment, the angle of the V-shaped notch is 30°-45°. Through multiple tests, it is found that if the above specifications are met, the performance of the antenna will be more optimized, especially in terms of return loss, the return loss of the return loss in the 2.4-2.48GHz frequency band and 5.15-5.875GHz frequency band is better than -18dB .

The invention discloses an electric power distribution cabinet with a multidata monitoring function. The electric power distribution cabinet comprises an outer cabinet body, an inner cabinet body is arranged in the outer cabinet body, an opening is formed in the top end of the inner cabinet body, multiple shelf boards used for placing electrical equipment are arranged in the inner cabinet body in layers, and vent holes are formed in each shelf board; a partition is arranged between the inner wall of the outer cabinet body and the outer wall of the inner cabinet body; first air openings are formed in the lower portion of the inner cabinet body, second air openings are formed in the upper portion of the outer cabinet body, and third air openings are formed in the lower portion of the outer cabinet body; as the partition is arranged, air enters from the third air openings, then enters the inner cabinet through the first air openings and flows out through the second air openings, heat is taken away through ventilation, and it is ensured that temperature in the power distribution cabinet is not too high. According to the principle that hot air will flow upwards, hot air will automatically disperse through the second air openings, and therefore outside low-temperature air continuously enters the third air openings.
