5results about How to "Avoid moisture short circuit" patented technology

The present invention belongs to the technical field of intelligent power distribution equipment, and specifically relates to a high-voltage power distribution cabinet with a pre-installed protection structure, including a shell, a water collection unit and a cleaning unit. The cleaning unit cleans the upper part of the inclined plate in the water collection unit. The inclined plate has a first mode and a second mode. When the inclined plate is in the first mode, the lower end of the inclined plate is connected to the water collection device, and the water collection device starts to collect water. When the inclined plate is in the second mode, the inclined direction of the inclined plate is opposite to the inclined direction when the inclined plate is in the first mode. The cleaning unit starts and moves from top to bottom along the inclined direction of the inclined plate. The inclined plate first selects the second mode and then the first mode. On non-rainy days, the temperature inside the shell is lowered by the air cooling unit, and on rainy days, the dust on the inclined plate is cleaned by the cleaning unit. The air cooling and water cooling can be automatically switched on rainy days and non-rainy days, ensuring that the electrical components can both dissipate heat normally and avoid short circuits due to moisture.

This utility model belongs to the field of power distribution cabinet technology, specifically a wiring-type power distribution cabinet, including a power distribution cabinet body. An installation frame is provided inside the power distribution cabinet body, and a fixed installation plate is provided on the end face of the installation frame. A pad is slidably installed inside the fixed installation plate to secure and protect the cable. A buffer installation plate is provided below the pad on the outer surface of the installation frame, and a slide rod is slidably installed inside the buffer installation plate. A drying chamber is provided on one side of the fixed installation plate against the inner wall of the power distribution cabinet body, and drying gas can be sprayed from the surface of the drying chamber. This utility model solves the problem of cables easily disconnecting from the power distribution device when pulled externally by setting up structures such as pads and slide rods. The slide rod also buffers the cables, improving their tensile strength. The collection box and drying chamber solve the problem of sand and moisture easily entering when the power distribution cabinet is installed outdoors, thereby improving the service life and adaptability of the equipment.

The present invention discloses a monitoring method and system for an intelligent power distribution cabinet, which relates to the technical field of power distribution cabinet monitoring, including: periodically detecting the humidity Sd of the power distribution cabinet; i , calculate and obtain the predicted value of humidity in the power distribution cabinet Yc i ; Get the usage time Sy of the power distribution cabinet j And humidity warning times Cs j , calculate the rust risk index Wx of the power distribution cabinet j ; Use the camera to collect the internal image of the distribution cabinet with high rust risk, and calculate the grayscale mean value Jph of the internal image of the distribution cabinet α And the grayscale mean Jhj of each component feature map αδ ; Calculate the rust degree index Csd of each component αδ and the normal grayscale threshold ΔH of each element δ , judge whether each component is rusted, and discover and deal with rust problems in time.

The utility model relates to the technical field of stepping motor drivers, and provides a bus control stepping motor driver, which comprises a shell and a control structure. According to the utility model, the control structure is arranged, the connecting end and the connecting port are electrically connected with the driver, and the general control circuit module can be directly inserted into the general driver, so that a plurality of modules can be controlled to move, the control is convenient, the synchronism is high, the number of controllers is reduced, and the cost is reduced; the operation control module is arranged to facilitate coordination and control of the whole system, and the sensor driving module is arranged to conveniently send data of a sensor connected with the connecting end and the connecting port to the operation control module. And the motor driving module is arranged to conveniently receive an instruction of the operation control module and control a stepping motor connected to an external interface.

The invention relates to the technical field of circulating water pump control, and discloses a central air conditioner circulating water pump energy-saving control device which comprises a mounting frame, a controller body is fixedly connected to the front side face of the mounting frame, a cushion block is fixedly connected to the front side face of the mounting frame, and an electric guide rail is fixedly connected to the front side face of the cushion block. According to the device, after the protection sliding cover makes contact with the limiting block, the protection sliding cover and the sealing baffle can seal the controller body, and the situation that the controller body is damaged, so that the circulating water pump cannot be controlled and adjusted is prevented; the clamping shaft is inserted into the through hole to lock the trapezoidal clamping plate and the protective sliding cover, the protective sliding cover is prevented from loosening, the protective effect of the protective sliding cover is improved, the trapezoidal clamping plate and the protective sliding cover lose limiting, the electric guide rail can drive the protective sliding cover to slide upwards, and the use convenience of the device is improved.
