Problems solved by technology

In practical applications, the space resources of the ring network cabinet are often very limited, while the traditional FTU must occupy a certain space resources during installation, and the purchase and installation of CT lines and control cables will undoubtedly increase the project cost
In addition, there is a risk of theft of CT and control cables. Once CT and control cables are stolen or damaged, it will directly affect the safe and stable operation of power distribution terminal equipment.

Embodiment Construction

[0021] Please check figure 1 and figure 2 , a modular feeder terminal for mounting in a switchgear cabinet, which includes a housing and a core board 10 , a control board 20 , a measurement board 30 and an operation panel 40 installed in the housing.

[0022] The core board 10 is connected to the control board 20, the measurement board 30 and the operation panel 40, processes and calculates the data sent on the control board 20 and the measurement board 30 (fault current, voltage, grounding, etc.), and sends instruction information to the operator Panel 40 is displayed. The core board 10 supports DC220V or DC48V power input. The core board 10 is provided with a network interface 11 and a remote / local access port 12 of the switch cabinet, and the network interface 11 and the remote / local access port 12 are connected outside the casing. In this embodiment, the network interface 11 is the RJ45 network interface. In this embodiment, the connection between the core board 10 an...

Abstract

The invention discloses a modular feeder terminal, which is used for being assembled in a cabinet body of a switch cabinet. The modular feeder terminal comprises a shell, a core panel, a control panel, a measuring panel and an operation panel, wherein the core panel, the control panel, the measuring panel and the operation panel are assembled in the shell; the core panel is connected with the control panel, the operation panel and the measuring panel. According to the modular feeder terminal disclosed by the invention, a modular design is adopted, the size is small, the modular feeder terminal can be integrated in a high-voltage switch cabinet in an embedded way, and the system integration of primary equipment and secondary equipment can be realized; a dedicated cable control wire, a cable control joint and a CT (Captive Test) wire are not needed, and all wiring operation can be totally completed before the high-voltage switch cabinet leaves a factory, so the cost of the cable control wire and the CT wire is saved, field installation steps are reduced, and the working efficiency of a field operator is greatly increased; the modular feeder terminal is integrated in the high-voltage switch cabinet in the embedded way, and thus the risk that a power distribution network is in failure caused as the cable control wire is stolen can be completely eradicated.

Description

technical field [0001] The invention relates to a feeder terminal, in particular to a modular feeder terminal. Background technique [0002] The traditional feeder terminal (FTU) adopts the structure design of the whole machine and adopts wall-mounted installation. Control cables and CT connecting cables are required to connect between the high switch cabinet and the FTU. In practical applications, the space resources of the ring network cabinet are often very limited, while the traditional FTU must occupy a certain space resources during installation, and the purchase and installation of CT lines and control cables will undoubtedly increase the project cost. In addition, there is a risk of theft of CT and control cables. Once CT and control cables are stolen or damaged, it will directly affect the safe and stable operation of power distribution terminal equipment. Contents of the invention [0003] The present invention provides a modular feeder terminal, which overcomes...
