Embodiment Construction

[0034] The following is based on figure 2 , image 3 and Figure 4 , give a preferred embodiment of the present invention, and give a detailed description, so that the functions, features and structures of the present invention can be better understood.

[0035] The structure of the remote controller of the overload relay of the present invention is as figure 2 . It includes a remote control signal processing device II and a current signal transmission device III. The control signal processing device II receives, processes and outputs a current signal from the closing commands of SB1 and SB2, and one end of the current signal transmission device III is connected with the signal output ports 9, 10 and 7, 8 of the control signal processing device II, and the other end Socket 11 in plug 31 and overload relay body 1 (referring to image 3 ) is connected, such as the aforementioned socket 11 and the coil J in the relay body (refer to Figure 4 ) connected.

Abstract

This invention discloses a long distance controller of an over-loading relay including: a control signal process device containing a signal receiving port, a signal output port and a signal process module, a current signal transfer device connected with the relay and the control signal process device, the signal receiving port of which receives signals to be processed by the process module then to output action current signals from the signal output port to be transferred to the over- loading relay by the current signal transfer device and operates the relay, thus, apart from its own operations, the relay can be controlled by the control signal process device remotely to realize the trip or reset of the relay.

Description

technical field [0001] The invention relates to a remote controller of an overload relay, in particular to a controller capable of tripping and / or resetting the overload relay at any moment through remote electrical connection. Background technique [0002] The main function of the overload relay is the overload and phase failure protection of the circuit and the motor. Its circuit principle is as follows: figure 1 As shown, when an overload and phase failure fault occurs in the circuit, and when the current flowing through the three-phase 1 / 2, 3 / 4, and 5 / 6 of the main circuit of the overload relay FR reaches the set value of overload and phase failure, the overload relay delays When the action trips, the auxiliary circuit 95 / 96 is disconnected, the main circuit is cut off, and the circuit and the motor are protected. When the circuit fault is eliminated and the overload relay cools down to the specified time, the overload relay is reset (automatically or manually), and the...
