The invention discloses a measurement and control integrated switch device which comprises a real-time sensing module, a control module, a switch control circuit, a positioning module and a communication module, wherein the real-time sensing module is used for generating corresponding sensing signals for output after sensing the high-voltage working signals of a monitored primary loop; the control module is used for receiving the sensing signals output by the real-time sensing module, computing the duty parameters of the primary loop according to the received sensing signals and controlling the switch control circuit to connect or disconnect the primary loop according to the computed duty parameters; the positioning module is used for obtaining the positioning information of the device and sending the obtained position information to the control module; and the communication module is used for obtaining the duty parameters and the position information from the control module and then sending the duty parameters and the position information to a power monitoring master station. According to the measurement and control integrated switch device, the primary loop can be disconnected when the circuits have failures and the power monitoring master station is capable of detecting the failure points and the failure reasons, so that the real-time remote measurement of the primary loop is realized through the power monitoring master station.

Description

technical field [0001] The invention relates to a power supply line equipment monitoring technology, in particular to a measurement and control integrated switch device and a control method. Background technique [0002] The electrical circuits that are connected to each other to form power generation, transmission, distribution or other production are called primary circuits. In order to prevent the normal operation of the entire primary circuit due to serious overload, short circuit or undervoltage faults in some circuits in the primary circuit, several primary switchgears are often installed in the primary circuit to cut off the faulty circuit in time. The structure of the existing primary switchgear includes a primary transformer, a control module and a mechanical switch. Among them, the primary transformer is used to convert the current working signal of the high-voltage line into a monitoring signal and provide it to the control module. When the monitoring signal valu...

Problems solved by technology

However, when the existing primary switchgear protects the circuit, in order to prevent the circuit from being disconnected frequently, the boundary value of the set working signal range is often larger than the actual working signal value in the circuit, so that the existing primary switchgear is prone to errors. Disadvantages of slow operation and response time

At the same time, when the circuit of the existing primary switchgear fails, the circuit can only be disconnected, and the master station cannot detect the location of the fault point and the cause of the fault. The function is relatively simple.
