Description
Technical Field
The invention relates to an overhaul device in a handcart switch cabinet bin.
Background
When the existing handcart switch cabinet is overhauled in the bin, one switch bin is overhauled, the whole bus is required to be stopped, and serious violations, safety accidents and the like exist in overhauling operation, so that the handcart switch cabinet needs to be further improved.
Disclosure of Invention
The invention aims to provide a handcart switch cabinet cabin overhaul safety device which is safe and convenient to use.
The technical scheme of the invention is as follows:
An overhaul safety device in handcart cubical switchboard storehouse, characterized by: a baffle plate for overhauling is arranged between the switch valve and the contact; the back of the baffle is provided with a magnet device which is attracted with the rear panel of the switch cabinet, the front of the baffle is provided with a hook which is matched with the insulating operating rod, and the baffle is locked with the upright rod in the switch cabinet by a lock to realize locking.
The baffle has the following three kinds: the first baffle is arranged at the lower part of the switch cabinet bin and is used for switch test isolation and overhaul of lower components in the bin; the second baffle is arranged behind the whole valve in the switch cabinet bin and is used for overhauling the switch valve in a fault manner; and a baffle III which is arranged at the position of the outgoing line fixed contact in the switch cabinet bin and is used for overhauling the outgoing line fixed contact.
The end of the insulating operating rod is provided with an insertion head matched with the hook.
The using method comprises the following steps: driving by using a handcart driving device, checking the jam condition of the mechanism, and simultaneously opening the valve; the baffle plate is arranged between the valve and the contact by using an insulating operating rod, and the iron absorbing device on the baffle plate is absorbed on the rear panel of the switch cabin; the baffle plate and the vertical rod in the switch cabinet are locked by a lock, so that locking is realized.
The iron absorbing devices are distributed in rectangular four points.
The hooks are distributed in rectangular four points.
The invention realizes effective isolation of the contacts in the switch cabins and the overhauling part, avoids the need of stopping the whole bus due to overhauling of one switch cabin, and improves the reliability of power supply and a large number of operation; meanwhile, the problem that the switch is pulled in and out during maintenance can be solved, the safety problem existing in the prior art by operation of operators is solved, and the use is safe and convenient.
