Abstract

A method of detecting a rejecting closing and rejecting opening fault of a disconnecting switch caused by a mechanical reason is characterized by comprising the following steps of a) detecting whether a grounding knife switch is opened in place; b) detecting whether water enters mechanism box; c) detecting a mechanical latch between the disconnecting switch and the grounding knife switch; d) detecting whether a rotating part is frozen to be jammed. When the fault occurs, by detecting according to the steps of the method and according to the fault possibility of a part, the faulted part can be detected out rapidly, and the favorable conditions are created for eliminating the fault rapidly.

Description

Mechanical reason causes disconnector to refuse to close, refuse a point fault detection method
Technical field
The present invention relates to mechanical reason causes disconnector to refuse to close, refuse a point fault detection method, belongs to high-tension electricity conveying equipment maintenance technique field.
Background technology
Visual plant during high voltage isolator in high-pressure delivery electricity, its generally by moving conductive rod and moving contact component, static contact component, disconnector base, support that porcelain vase, operation porcelain vase, porcelain vase base, gear train, operating mechanism etc. form; Because it is used in high pressure occasion, when breaking down, require quick failure judgement point, to fix a breakdown in time.
The maintenance technique of high voltage isolator part is now mature on the whole, therefore, to the emphasis of the maintenance of breakdown switch, is rapid failure judgement position, to get rid of in time.
Summary of the invention
According to above-mentioned requirements, the object of this invention is to provide mechanical reason causes disconnector to refuse to close, refuse a point fault detection method, when a failure occurs it, likelihood of failure size is produced according to parts, detect by step according to the method, trouble location can being detected fast, creating favorable conditions for fixing a breakdown rapidly.
For achieving the above object, the present invention is realized by following technological means:
Mechanical reason causes disconnector to refuse to close, refuse a point fault detection method, it is characterized in that: comprise the following steps:
A) whether separating brake puts in place to detect earthing switch blade;
B) whether testing agency's case intakes;
C) mechanical latching between disconnector and earthing switch blade is detected;
D) the whether icing bite of rotary part is detected.
Further:
Described mechanical reason causes disconnector to refuse to close, refuse a point fault detection method, and it is characterized in that: described step a) comprises, as not in place in earthing switch blade separating brake, reply puts in place.
Described mechanical reason causes disconnector to refuse to close, refuse a point fault detection method, it is characterized in that: described step b) comprise, as mechanism case is not intake, proceed to step c); As mechanism case water inlet, enter following steps:
B1) as not in place in belonged to mechanism's lubrication, after adding moderate lubrication oil, manually divide, close several times, and then carry out electric operating;
B2) if corrosion is serious, Disintegration overhaul, lubrication are carried out to corrosion parts, changes parts if desired.
Described mechanical reason causes disconnector to refuse to close, refuse a point fault detection method, it is characterized in that: described step c) comprising:
C1) as mechanical latching has distortion, pull down and correct, confirm that position is correctly installed afterwards;
C2) if mechanical latching is without distortion, completely separately put in place by earthing switch blade, manual operation disconnector, checks the correctness of mechanical locked position of coupler, as found position setup error, again correctly installs.
Described mechanical reason causes disconnector to refuse to close, refuse a point fault detection method, it is characterized in that: described steps d) comprise, manual operation disconnector, find bite position, the process of employingization ice mode; For three phase mechanical linkage mechanism, the connecting rod untied between phase and phase carries out phase-splitting inspection, and then removing is frozen.
The invention has the beneficial effects as follows: when a failure occurs it, produce likelihood of failure size according to parts, detecting by step according to the method, trouble location can be detected fast, creating favorable conditions for fixing a breakdown rapidly.
Embodiment
Mechanical reason causes disconnector to refuse to close, refuse a point fault detection method, it is characterized in that: comprise the following steps:
A) whether separating brake puts in place to detect earthing switch blade;
When the non-separating brake of earthing switch blade puts in place, the mechanical latching between earthing switch blade and disconnector will the feed motion of locking disconnector, thus causes disconnector not close a floodgate.
B) whether testing agency's case intakes;
Mechanism case is intake, each pivot pin, bearing rust, will to make point, the increase of combined floodgate resistance, when resistance increases to a certain degree, the conjunction of refusing of disconnector will be caused to refuse point.
C) mechanical latching between disconnector and earthing switch blade is detected;
Be provided with mechanical latching between disconnector and earthing switch blade, installation site mistake or mechanical latching distortion after maintenance, refusing when often causing operation is closed, is refused a point fault.
D) the whether icing bite of rotary part is detected.
Winter temperature is low, and rotary part often causes icing bite due to the reason such as ponding, accumulated snow, thus causes the conjunction of refusing of disconnector to refuse point.
Further:
Described mechanical reason causes disconnector to refuse to close, refuse a point fault detection method, and it is characterized in that: described step a) comprises, as not in place in earthing switch blade separating brake, reply puts in place.
Described mechanical reason causes disconnector to refuse to close, refuse a point fault detection method, it is characterized in that: described step b) comprise, as mechanism case is not intake, proceed to step c); As mechanism case water inlet, enter following steps:
B1) as not in place in belonged to mechanism's lubrication, after adding moderate lubrication oil, manually divide, close several times, and then carry out electric operating;
B2) if corrosion is serious, Disintegration overhaul, lubrication are carried out to corrosion parts, changes parts if desired.
Described mechanical reason causes disconnector to refuse to close, refuse a point fault detection method, it is characterized in that: described step c) comprising:
C1) as mechanical latching has distortion, pull down and correct, confirm that position is correctly installed afterwards;
C2) if mechanical latching is without distortion, completely separately put in place by earthing switch blade, manual operation disconnector, checks the correctness of mechanical locked position of coupler, as found position setup error, again correctly installs.
Described mechanical reason causes disconnector to refuse to close, refuse a point fault detection method, it is characterized in that: described steps d) comprise, manual operation disconnector, find bite position, the process of employingization ice mode; For three phase mechanical linkage mechanism, the connecting rod untied between phase and phase carries out phase-splitting inspection, and then removing is frozen.
