Embodiment 1

[0038] Such as figure 1 As shown, a real-time online display and control leakage intelligent protector includes a control panel 1, and the control panel 1 is used to set related operating units, which is convenient for users to use; the two ends of the control panel 1 are provided with incoming line interfaces 2 and Outlet interface 3, the interior of the control panel 1 is provided with a zero-sequence transformer, a shunt release, an operating mechanism and a controller, the zero-sequence transformer is used to detect leakage current in the line, and the shunt trip The device is used to execute the instructions of the controller to disconnect the circuit, and the operating mechanism is used to manually open or close the circuit. The operating handle 5 of the operating mechanism extends out of the control panel 1, and the user closes or disconnects the circuit by turning the operating handle 5. circuit. The control panel 1 is provided with a leakage current display screen 6 ...

Embodiment 2

[0046] Such as figure 2 , image 3 As shown, on the basis of the above-mentioned embodiments, the control panel is further provided with a leakage current threshold selection knob 4, and the leakage current threshold selection knob 4 is connected to the controller to set the leakage current threshold; and The controller can also be connected with an alarm device 8, and when the value of the leakage current exceeds the preset leakage current threshold, the alarm device 8 starts, especially in the mode of forced non-tripping, Through the alarm device 8 on-site personnel can keep abreast of the on-site situation, facilitate its timely processing, and reduce the occurrence of accidents; in order to facilitate the user's setting during use, the tripping mode setting mechanism 7 can be set on the control panel 1. The tripping mode setting mechanism 7 is connected with the controller, and the tripping mode can be set, so that the tripping mode can be set according to the needs of t...

Abstract

The invention relates to an intelligent real-time on-line displaying and controlling leakage protector which comprises a control panel, wherein a wire inlet interface and a wire outlet interface are arranged at the end part of the control panel; a zero sequence transducer, a shunt releaser, an operating mechanism and a controller are arranged in the control panel; a leakage current display screen is arranged on the control panel; a tripping mode and a tripping mode selecting unit are arranged in the controller; the tripping mode comprises a forcing non-tripping mode, a delayed tripping mode and a normal tripping mode; the tripping mode selecting unit is used for selecting the tripping mode according to the size of a leakage current detected by the zero sequence transducer and switching among the modes according to the change of the detected leakage current. The invention provides an intelligent real-time on-line displaying and controlling leakage protector which is used for solving the technical problems of a breaker in the prior art that an instantly increased leakage current is subjected to tripping, service life of equipment is influenced, working efficiency is reduced and treatment cannot be performed according to specific working conditions.

Description

technical field [0001] The invention relates to a circuit breaker protection device, in particular to a real-time online display and control leakage intelligent protector. Background technique [0002] Open circuit protection device refers to the switching device that can close, carry and break the current under normal circuit conditions, and can close, carry and break the current under abnormal circuit conditions (including short circuit conditions) within a specified time. In a common circuit, there is generally a leakage current, which is formed by the surrounding medium or insulating surface between electrically insulated metal parts, or between a live part and a grounded part, in the absence of a fault applied voltage. The current is called leakage current, also known as leakage current. Excessive leakage current not only reduces the efficiency of electric energy, but also causes danger to the external environment and easily leads to electric shock accidents, so the mo...
