Abstract
The utility model discloses an anti-condensation drainage system of an enclosed bus. The anti-condensation drainage system comprises water collecting funnels, drainage pipes, a water tank and a drainage valve; one water collecting funnel is arranged on each of corners of the enclosed bus; one drainage pipes is connected with each of the water collecting funnels via one flange; all drainage pipes are gathered in the water tank in a parallely connected way; the lower end of the water tank is communicated with the drainage valve; each water collecting funnel is made of an insulator base of the enclosed bus and is directly welded on a housing of the enclosed bus; each insulator base of the enclosed bus is connected with a base cover plate via a screw, a seal ring is arranged between the insulator base of the enclosed bus and the base cover plate, and sealant is put on the seal ring; a hole is arranged in each base cover plate and one drainage pipe is welded on each of base cover plate. The anti-condensation drainage system of the enclosed bus provided by the utility model has a good effect, and is capable of effectively monitoring a water gathering situation in the sealed bus and draining the water away and ensuring safe running of a machine set, is simple and effective in principle, easy to achieve, low in manufacture cost, and easy to repair, maintain and change, and is very practical, and a big problem can be resolved by a small device.
Description
Technical field
The utility model relates to a kind of drainage arrangement, relates in particular to a kind of enclosed bus of generator and installs the anti-condensation drainage arrangement additional.
Background technology
Big power station's unit enclosed busbar is after the operation of long period, all exist sealing property to descend, there are the phenomenons such as aged deterioration in enclosed busbar supporting insulator base seal pad, peep-hole sealing gasket, nonmetal expansion joint sealing gasket etc., when rainy season, cause easily the enclosed busbar water inlet, Winter-Spring, transition period autumn and winter, dewfall also occurs in enclosed busbar easily.The enclosed busbar of general unit is without drainage arrangement, in case inner ponding or the dewfall of producing of enclosed busbar, ponding is difficult for discharging.
Water inlet and dewfall cause the decreasing insulating of enclosed busbar in the enclosed busbar, and the action of enclosed busbar ground connection and generator unit ground protection will occur when serious, and unplanned stoppage in transit event occurs unit.
The utility model content
For addressing the above problem the open following technical proposals of the utility model:
A kind of enclosed busbar anti-condensation drainage system, comprise: funnel catchments, drainage pipe, water tank and draining valve, the described funnel that catchments is installed in each turning Kou Chu of enclosed busbar, described drainage pipe is connected by flange with the described funnel that catchments, and drainage pipe parallel connection everywhere is concentrated to water tank, and described water tank lower end is communicated with and connects draining valve.The described funnel that catchments is made by the female insulator foot of envelope, directly is welded on the female shell of envelope, and the female insulator foot of described envelope is that screw rod is connected with the base cover plate, and the centre installs sealing ring additional and coats fluid sealant, perforate welding drainage pipe on the base cover plate.
Further, described water tank installs level measurement meter additional.Described water tank is the cuboid that is welded by aluminium sheet.
Further, the described funnel that catchments is installed on the horizontal segment of each 150mm-200mm of mouth place, turning of enclosed busbar.
The utility model provides enclosed busbar anti-condensation drainage system, and is respond well, and ponding situation and in time draining in can the effective monitoring enclosed busbar guarantee unit safety operation.
Description of drawings
Fig. 1 is enclosed busbar anti-condensation drainage system structure chart.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment one
At unit isolated-phase enclosed bus and main transformer, high factory becomes, " ┌ " and " ┬ " or each turning mouth of " ┑ " shape that desulfurization becomes, horizontal segment lowest part from turning mouth 150mm-200mm, install enclosed busbar anti-condensation drainage system as shown in Figure 1 additional, comprise the funnel that catchments, drainage pipe, water tank and draining valve, the described funnel that catchments adopts the female insulator foot of envelope as funnel, described funnel and enclosed busbar adopt the aluminium weldering, its base diameter is Ф 265 ㎜, base directly is welded on the enclosed busbar shell, base is that screw rod is connected with the base cover plate, and the centre installs sealing ring additional and coats fluid sealant, opens the hole that diameter is Ф 25 ㎜ on the base cover plate, and welding an aluminium matter draining tube head as the neck of the funnel that catchments, the neck tube head of the funnel that catchments is that flange is connected with drainage pipe.Drainage pipe parallel connection everywhere is concentrated to water tank, and described water tank lower end is communicated with and connects draining valve.Install the funnel that catchments additional as an example of 200mm around the corner example, drainage pipe parallel connection everywhere is concentrated to water tank, and described water tank lower end is communicated with and connects draining valve, and draining valve is in open mode.
Further, install level measurement meter on the water tank additional, find that in spot check tour process the water tank level measurement meter shows water level, have water to discharge in the expression bus shell, then open the Draw off valve of water tank lower end, water is excluded.Water tank adopts the aluminium sheet welding and guarantees sealing property.
The utility model provides enclosed busbar anti-condensation drainage system, respond well, ponding situation in can the effective monitoring enclosed busbar and in time draining, guarantee unit safety operation, this programme principle is simply effective, practical function and easily realization, and skinny device solves large problem, cost is low, and easily repair and maintenance is changed.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
