Embodiment Construction

[0019] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0020] refer to figure 2 As shown, a residual current coil disconnection detection device of the present invention includes a CPU main control module 1, a residual current detection circuit 2, a communication module 3, and a power supply module 4. The CPU main control module is respectively connected to the residual current detection circuit, the communication module, The power module and the residual current detection circuit are connected to the residual current coil. The residual current detection circuit is used to detect whether the external residual current coil is disconnected, and transmits the detection result to the CPU main control module, and the communication module connected to the CPU main control module is used for communication between the upper computer and the CPU main control module. The power supply module is used t...

Abstract

The invention discloses a residual current coil disconnection detection device which comprises a CPU main control module, a residual current detection circuit, a communication module, and a power supply module. The CPU main control module is connected to the residual current detection circuit, the communication module, and the power supply module. The residual current detection circuit is connected to a residual current coil. The invention also discloses a detection method of the residual current coil disconnection detection device. According to the residual current coil disconnection detection device, whether an external connection residual current coil is disconnected or not can be detected, the device is convenient to use, the detection is rapid and reliable, and the device has a good application prospect.

Description

technical field [0001] The invention relates to a detection device, in particular to a residual current coil disconnection detection device, and also relates to a detection method of the residual current coil disconnection detection device. The invention belongs to the field of detection device design. Background technique [0002] The residual current detection device generally consists of a detector and a detection coil. Such as figure 1 As shown, the current coil is connected to the detector through two current wires to form a residual current loop. During the installation of the residual current detection device, sometimes the detector and the detection coil may be forgotten; it may also be connected, but the current wire may fall off during the placement of the residual current detection device. When the residual current value in the residual current device is zero, it cannot be judged that the current line between the detector and the detection coil is not connected...
