Description
Technical field
This disclosure relates to power system security protective device correlative technology field, in particular to a kind of portable
Hanging device of safety belt for overhauling transformer and application method.
Background technique
The statement of this part only there is provided background technical information relevant to the disclosure, not necessarily constitutes first skill
Art.
Transformer is widely used large number of as the common power equipment in electric system, and there are many model, electricity
Power safety work order has relevant regulations: " operation that all eminences in height of fall datum level 2m or more carry out, should all be regarded as
High-rise working.When high-rise working, the hook or rope of safety belt should be hung on solid firm component, or aim at hanging safety belt use
Wirerope on, and should be in such a way that height hangs low use." transformer ontology it is higher, the height of 35KV transformer body just surpasses
2 meters have been crossed, and the body height of 110KV, 220KV, 500KV transformer is far longer than this height, and maintenance personal is frequently necessary to
It climbs up transformer and is engaged in maintenance task on the case lid of transformer.
Safety belt suspension device will not be generally arranged in the ontology transformer of transformer when leaving the factory, inventors have found that at present
In the upkeep operation of transformer, since the maintenance personal that unsuitable hanging point has does not use safety belt directly, on the transformer
During the transfer tasks job site of face, it was easy to happen because body is unbalance, so as to cause safety accident.Alternatively, some maintenances
Personnel in maintenance, safety belt is beaten be buckled in oil pipe, below bushing transformer riser station, the hole for hoist at edge etc., easily cause
Pipe leakage oil, porcelain body equipment damage etc. and easily cause the personal injury fallen and hurted sb.'s feelings；It uses, is not inconsistent for low extension is high setting
Safety prescribed requirement is closed, operating personnel's safety is seriously threatened.In the prior art with safety belt suspension device on the transformer,
Volume is larger inconvenient to carry or needs to reequip transformer body, such as needs suspension arrangement being welded on transformation
On device.Transformer it is large number of, using it is fixed on the transformer (as welded) by the way of, on the one hand cause waste, increase
Human cost and material cost；On the other hand the body construction that transformer is changed after being arranged increases rapid wear point, and solid
It cannot be moved easily after fixed, the maintenance of later period transformer is had an impact.
