Problems solved by technology

[0008] However, since conventional controllers control circuit breakers based on electrical signals input through signal lines, computers or maintenance personnel that manage the power system must be located adjacent to the control panel to directly operate the circuit breakers
That is, there is the inconvenience that the maintenance person needs to be located in a restricted area so that he can directly operate the circuit breaker
[0009] In addition, in the conventional controller of the circuit br...

Embodiment Construction

[0017] The following will refer to the attached Figure 2~4 The preferred embodiment of the circuit breaker remote controller of the present invention is described in detail.

[0018] figure 2 is a block diagram showing a circuit breaker remote controller according to the first embodiment of the present invention.

[0019] Such as figure 2 As shown, the circuit breaker remote controller 200 includes: a receiver 201, which is used to transmit data from maintenance personnel through a BS (base station transceiver subsystem) 100 or a transmitting station (not shown) of a wireless communication network or a mobile communication network. The wireless communication terminal or mobile phone of the circuit breaker receives a switch control signal or a trip signal (in the form of a wireless control signal); the control unit 202 is configured to receive power from the power supply unit 300 when the trip signal is input from the receiver 201, and generating a first control signal an...

Abstract

In a remote controller of a circuit breaker capable of making an maintenance man control a circuit breaker instantly and safely at any place without approaching a certain area such as a control board or a control room, the circuit breaker includes a receiver for receiving a radio control signal for turning on/off or tripping a circuit breaker; a control unit for generating a first control signal or a second control signal depending on the radio control signal inputted from the receiver; a motor driver for controlling the on/off operation of the circuit breaker depending on the first control signal; and a trip unit for tripping the circuit breaker depending on the second control signal.

Description

technical field [0001] The present invention relates to a circuit breaker, and more particularly to a circuit breaker remote controller that enables maintenance personnel to remotely control the circuit breaker without access to the circuit breaker or a control panel. Background technique [0002] Generally, a circuit breaker includes an insulating case and a circuit breaker and a trip unit installed therein. When the circuit from the power source to the electric load is in one of overload and disconnected states or short-circuited, the circuit breaker automatically Cut off the circuit. [0003] Circuit breakers can be broadly classified into MCCB (molded case circuit breaker) for protecting the above circuits and ELB (Earth Leakage Breaker) for preventing electric shock and fire by sensing earth leakage . [0004] figure 1 is a block diagram showing a prior art circuit breaker controller. [0005] Such as figure 1 As shown, the controller of the circuit breaker 104 inc...
