Abstract
The utility model discloses an indoor moisture-proof cable channel, which comprises a channel groove and a channel groove cover plate set. The channel groove cover plate set includes a sealing cover plate and a ventilation cover plate which are arranged in parallel along the channel groove, and two ends of the sealing cover plate and two ends of the ventilation cover plate are respectively overlapped at two lateral edges of the channel groove. When the cable channel is used, the inside of the channel groove is communicated with the inside of a room into a whole via the ventilation cover plate and can similarly keep dry under the action of an indoor ventilation dehumidification device, and the cable channel effectively prevents accumulated moisture inside the channel groove from continuously affecting indoor humidity, prevents condensation generated on power supplying equipment such as a switching post and the like to cause failures such as short circuit and the like, and guarantees safe and stable running of the power supplying equipment.
Description
Technical field
The utility model relates to the electrical building facility, and particularly a kind of switching station etc. of being arranged at needs indoor moisture resistant cable ditch in moistureproof, the anti-condensation power supply unit installation room.
Background technology
Power supply unit is as indispensable element in the electric power system, its operation conditions will influence the stability and the fail safe of system, in case break down, with the normal power supply that directly influences the user, cause enormous economic loss, also may cause accidents such as fire, blast when serious.
Add up according to interrelated data, in the power supply unit fault because of making moist or the condensation fault that causes that is short-circuited accounts for significant proportion, in switching station short trouble statistics, cause because of condensation near 60%, cable trough in the equipment installation rooms such as existing switching station all excavates at below ground, and all adopt cement plate as cover plate, gas permeability is bad, make the moisture in the groove also be difficult for distributing eliminating, indoor humidity is produced long lasting effect, cause easily on the equipment such as switching station and produce condensation, cause faults such as equipment short circuit.
At above-mentioned deficiency, need existing cable trough its air permeability that improves is reduced indoor humidity, in order to avoid influence the normal operation of indoor equipment.
The utility model content
In view of this, the utility model provides a kind of indoor moisture resistant cable ditch, and this cable trough has good air permeability, can effectively reduce its influence to indoor humidity, in addition, this cable trough effectively inside and outside the isolation ward, prevents to cause humidity excessive and unfavorable to equipment in outdoor water and the moisture inlet chamber.
Indoor moisture resistant cable ditch of the present utility model, comprise groove and Ditch cover board group, described Ditch cover board group comprises airtight cover plate and vent flap, and described airtight cover plate and vent flap are set up in parallel along groove, and their two ends separately ride over the both sides of groove respectively along last.
Further, described vent flap comprises the skeleton and the filter screen of stacked setting, and described skeleton is formed by two groups of mutual interconnections of the steel bar that is set up in parallel;
Further, described airtight cover plate and vent flap spacing parallel arranging are provided with;
Further, be provided for the sealed wall that prevents that outdoor air and water from entering in the described groove;
Further, described airtight cover plate is a cement cover board.
The beneficial effect of utility model: indoor moisture resistant cable ditch of the present utility model, comprise the groove and the Ditch cover board group that are used to install cable, described Ditch cover board group comprises airtight cover plate and vent flap, described airtight cover plate and vent flap are set up in parallel along groove, their two ends separately ride over the both sides of groove respectively along last, during use, groove inside became one by vent flap and indoor the connection, under the effect of room ventilation dehumidification equipment, groove inside can keep dry equally, effectively avoided building up in the groove moisture indoor humidity has been produced long lasting effect, prevent to produce condensation on the power supply unit such as switching station and cause fault such as short circuit, ensured the safe and stable operation of power supply unit.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of Ditch cover board group;
Fig. 3 is the A-A profile of Fig. 1.
Embodiment
Fig. 1 is a structural representation of the present utility model, Fig. 2 is the structural representation of Ditch cover board group, Fig. 3 is the A-A profile of Fig. 1, as shown in the figure: the indoor moisture resistant cable ditch of present embodiment, comprise the groove 1 and the Ditch cover board group that are used to install cable, described Ditch cover board group comprises airtight cover plate 2 and vent flap 3, described airtight cover plate 2 and vent flap 3 are set up in parallel along groove 1, their two ends separately ride over the both sides of groove 1 respectively along last, groove inside became one by vent flap and indoor the connection, under the effect of room ventilation dehumidification equipment, groove inside can keep dry equally, effectively avoid building up in the groove moisture indoor humidity has been produced long lasting effect, prevented to produce condensation on the power supply unit such as switching station and cause fault such as short circuit, ensured the safe and stable operation of power supply unit.
In the present embodiment, described vent flap 3 comprises the skeleton 4 and the filter screen 5 of stacked setting, described skeleton 4 by two groups of steel bars that are set up in parallel intersect mutually the welding form, part as ground, utilize skeleton to increase the intensity of vent flap, make it have enough bearing capacitys, simultaneously, filter screen can prevent that also a certain size foreign material from entering groove.
In the present embodiment, described airtight cover plate 2 and vent flap 3 than spacing parallel arranging setting in 2: 1, when reaching good ventilation effect, can reduce the consumption of vent flap, the construction cost of reduction cable trough by quantity as far as possible.
In the present embodiment, be provided for the sealed wall 6 that prevents that outdoor air and water from entering in the described groove 1, the outer cable of sealed wall parcel junction chamber is avoided impacting in the outdoor empty G﹠W inlet chamber and to indoor humidity under the situation that does not influence cable routing.
In the present embodiment, described airtight cover plate 2 is a cement cover board, is easy to obtain, and cost is low.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
