Embodiment 1

[0029] refer to Figure 1~6 , which is the first embodiment of the present invention, this embodiment provides a dedicated device for an FTU dedicated power supply, and the dedicated device for an FTU dedicated power supply includes a terminal body 100 and a stable energy system 200 . The terminal body 100 includes an intermittent drainage assembly 103 arranged inside it, through which the intermittent drainage of the four groups of water-absorbing fiber cotton 102 can realize the function of preventing rainwater leakage for a long time.

[0030] Specifically, the terminal body 100 includes heat dissipation holes 101 arranged on both sides of the terminal body 100, water-absorbing fiber cotton 102 attached to the heat dissipation holes 101, and an intermittent drainage assembly 103 arranged on the top of the terminal body 100. ; Water-absorbing fiber cotton 102 can absorb the rain and snow penetrating into the terminal to prevent damage to internal components.

[0031] The st...

Embodiment 2

[0041] refer to figure 1 and figure 2 , is the second embodiment of the present invention, which is different from the first embodiment: it also includes a drain port 104, a rainproof plate 105, and a water collecting plate 106. In the previous embodiment, the convenient live test auxiliary tool includes a terminal body 100 and a stable energy system 200 . The terminal main body 100 includes an intermittent drainage assembly 103 inside, through which the intermittent drainage assembly 103 drains the four groups of water-absorbing fiber cotton 102 intermittently, so as to realize the function of preventing rainwater leakage for a long time.

[0042] Specifically, the terminal body 100 includes heat dissipation holes 101 arranged on both sides of the terminal body 100, water-absorbing fiber cotton 102 attached to the heat dissipation holes 101, and an intermittent drainage assembly 103 arranged on the top of the terminal body 100. ; Water-absorbing fiber cotton 102 can absorb...

Abstract

The invention discloses a special device for an FTU special power supply, and the device comprises a terminal main body and a stable energy system. The terminal main body comprises heat dissipation holes, water absorption cellucotton and an intermittent drainage assembly. The stable energy system comprises an input module, a first power supply module, a current-limiting resistor module, a super capacitor module and a second power supply module. According to the device, the requirements of a core device and high-power switching operation are met through a stable energy system, water absorptioncellucotton is extruded and drained through the intermittent drainage assembly, rainwater is prevented from seeping into a terminal through the water absorption cellucotton, and the first drainage component and the second drainage component are driven by the motor to extrude from the two sides to the middle at the same time; water in the water-absorbing cellucotton is quickly emptied, and the working efficiency is improved. And intermittent extrusion drainage is carried out on one side during drainage, so that the situation that the heat dissipation capacity of the terminal is affected due tothe fact that the water-absorbing cellucotton is extruded again when absorbing water insufficiently is avoided.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation equipment, in particular to a special device for an FTU special power supply. Background technique [0002] The current distribution switch monitoring terminal (FTU for short) is installed on the column, and performs remote control, remote signaling, and fault detection functions for the switch on the column, and communicates with the distribution automation master station to provide distribution system operation and various parameters. That is to monitor and control the required information, including switch status, electric energy parameters, phase-to-phase fault, ground fault and fault parameters, and execute the commands issued by the power distribution master station, adjust and control the power distribution equipment, and realize fault location and fault detection. Features such as isolation and fast restoration of power to non-faulty areas. The existing power...
