Description
Technical Field
The invention relates to the technical field of power equipment, in particular to a GIS voiceprint signal acquisition device.
Background
The invisible of GIS switch contact of transformer substation hides very big electrical operation risk, and the case that leads to because the switch on-off of switch off is not in place occasionally takes place in recent years. Because GIS equipment structure's limitation, the operating personnel can't direct observation the actual position of switch at the in-process of operation, though can use GIS position observation pole, nevertheless the flashlight on the observation pole can't stretch into in the narrow and small mechanism clearance. For example, the GIS device disconnecting link mechanical position observer disclosed in Chinese patent CN202957481U has a large size and cannot extend into a narrow gap, and an operator still needs to climb up the device to observe the light source condition in an observation hole on the opposite side, which is time-consuming and difficult to operate. And the mechanism rotation sound of switch divide-shut brake in-process is inaudible, and the arc sound of discharging that the switch divide-shut brake is not in place arouses is inaudible to the actual position of unable effectual judgement switch divide-shut brake, unable convenient accurate monitoring operation condition has brought a great deal of difficult problems and potential safety hazard for equipment operation maintenance and operation.
