Intelligent double-control electrical leakage breaking alarm

Abstract

The invention provides an intelligent double-control creep cutting alarm which has characteristics in that: including a metal casing, an intelligent detection encoder, a switch electrical source, a creep breaker; the intelligent detection encoder input port connects with a power network input port; the intelligent detection encoder input port also connects with a creep voltage collecting line; the creep voltage collecting line connects with the metal casing, and connects with a distribution equipment drain electrode through the metal casing; the switch electrical source is series connected between the intelligent detection encoder input port and power network input port for supplying power to the intelligent detection encoder; the creep breaker is series connected between the power network input port and output port; the intelligent detection encoder output port connects with the creep breaker; the creep breaker controls opening/cutting of the power network input port and output port according with output signal of the intelligent detection encoder. The alarm detects power network safety state according with creep voltage, and is used for power supply environment characteristic in field operation, ensures using electricity safely in field operation.

Description

technical field [0001] The invention relates to a circuit protection device, in particular to an intelligent dual-control leakage cut-off alarm designed for the characteristics of the field power supply environment. Background technique [0002] For many tasks that require field operations such as oil exploration and mineral extraction, field power consumption is a big problem. It is directly related to whether the instruments and equipment for field operations can operate normally and whether the staff can live normally. Especially in recent years, with the continuous expansion of production scale and the continuous improvement of field work conditions, the power consumption of field work is also gradually increasing, and the problem of safe use of electricity in the field has become more and more prominent. Generally, in actual work, the field power system often needs to set up special power distribution equipment. In order to ensure the safety of power consumption of th...
