Abstract

The invention discloses an emergency stop device of a transformer substation hot-line work robot, selects a composite button, and provides a new method for wiring in a failure safety mode. Two pairs of normally closed contacts are connected to the positive electrode end of a power supply in series, and two pairs of normally open contacts are connected to the negative electrode end of the power supply in parallel; the method comprises the following steps of: converting circuit connection by utilizing a composite button, connecting a coil, a diode, a capacitor and a resistor of the direct current contactor in parallel to form an RLC parallel oscillating circuit, pressing the composite button in an emergency state, disconnecting a normally closed contact, and enabling current flowing through the coil to form a path through the diode so as to eliminate residual magnetism of the iron core of the direct current contactor. Overvoltage caused by coil current abrupt change is prevented; when the direct-current contactor is started, the normally open contact is closed, the direct-current contactor coil, the diode, the capacitor and the resistor are connected in parallel to form an RLC parallel oscillation circuit, oscillation current is generated, residual magnetism of the iron core of the direct-current contactor is eliminated in time, and therefore the technical problems that in the prior art, reliability is poor, and quick-action performance is poor are solved.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to an emergency stop device for a live working robot in a substation. Background technique [0002] The high-voltage electrical equipment in the substation is arranged at intervals, requiring the live working robot to move autonomously or remotely between numerous and dense equipment for live work; due to various factors such as human misoperation and abnormal robot actuation mechanism, the live working robot may be out of control , cannot move or work as expected, causing damage to surrounding personnel and power substation facilities, so the mobile robot must have at least one emergency stop device, which is used to stop the robot in an emergency when the robot fails or people are in danger, avoiding or reducing There are various dangers to people. [0003] The existing emergency stop device has the function of category 0 shutdown or category 1 shutdown. It is w...
