Background technology
With the development of urban power distribution network, overhead line power supply mode is phased out, and ring network power supply is that local transmission network is main
Structure type.Ring main unit is as a kind of economic, flexible power distribution equipment, in urban and rural power grids, substation in zone, industrial and mining enterprises and quotient
The industries such as industry building are used widely.It is extremely complex due to the use of environment, especially in coastal area and in mist, dew, rain, snow
Under equal weather, electrical equipment is easy to make moist, and damp-heat air touches colder electrical equipment metal shell when serious, works as metal
When surface temperature is less than the dew-point temperature of air, is easily formed and condensed in metal surface, generate condensed water.Electrical equipment makes moist, first
First show that the decreasing insulating of equipment, insulation ag(e)ing accelerate, the electrical equipment being in for a long time in wet environment, if do not used
Moisture preventive measure, service life can be greatly lowered, and electric leakage, short circuit are easily caused when especially insulating surface pollutant accumulation is more,
So as to cause serious electric fault and accident.In recent years, accident happens occasionally caused by being made moist due to ring main unit, not only can in this way
It causes large area, have a power failure for a long time, loss is big, but also the catastrophic consequence such as easily cause fire, explosion, therefore as electric
Net a big hidden danger of safety.In order to ensure that power equipment safety is run, electric power facility service life is improved, prevention or reduction are taken
Environmental condition increases reliability of operation in harsh environment, reduces accident to the adverse effect of electrical equipment reliability,
Business Economic Benefit and social benefit are improved, it is a point necessity to take appropriate measures.Ring main unit cable vault is moisture-proof at present generally adopts
Accomplish to seal as possible with cabinet door, cabinet, avoids the intrusion of moisture or periodical power failure from replacing drier, in mist, dew, rain, snow etc.
The tour for reinforcing personnel under weather, when finding condensed water, by the way of artificially being wiped after equipment has a power failure, because handling problems
Power failure work considerably increase unplanned power off time, to seriously affect Utilities Electric Co.'s operational reliability index, simultaneously
Also increase the labor intensity and workload of operation maintenance personnel.
Utility model content
Therefore, for above-mentioned problem, dry, dimension that the utility model proposes a kind of simple in structure, effective holding cable vaults
The convenient novel 10KV ring main units cable vault damp-proof device of shield.
To solve this technical problem, the utility model takes following scheme：A kind of novel 10KV ring main units cable vault is moisture-proof
Device, including solar photovoltaic assembly, accumulator, controller, multiple humidity sensors and multiple heaters, the solar energy
It is to charge set on the indoor accumulator of ring main unit cable that volt component wears ring main unit cable vault through insulated conductor, the accumulator warp
Device and each heating installation power supply, each heater are laid in ring main unit cable vault insulated conductor respectively in order to control, each wet
Degree detector is laid in respectively in ring main unit cable chamber interior walls, and each hygrosensor is connected with controller input terminal,
Each heater is separately connected and is controlled by controller.
Further to improve, the heater is three, and three heaters are respectively arranged in the top of ring main unit cable vault
In the middle part of side wall, in the middle part of left part madial wall and on right part madial wall middle part.
Further to improve, the heater is patch type heater.
Further to improve, the humidity sensor is eight, and eight humidity sensors are respectively arranged on ring main unit cable vault
Eight edges of inner wall.
By using preceding solution, the utility model has the beneficial effects that：It is by using solar photovoltaic assembly
Controller and heating installation power supply monitor the humidity of each region in ring main unit cable vault using multiple humidity sensors in real time, when
The heater work of controller control corresponding region, heater generate heat, make ring around when one of region is more than humidity
Border temperature increases, and moisture is discharged outside cabinet, by multiple humidity sensors to more accurately being supervised inside ring main unit cable vault
It surveys, and multiple heater heating is set, removing moisture is efficient, to effectively keep 10kV ring main unit cables indoor dry
Dry, dampproof effect is good, simple and reasonable for structure, installation maintenance is easy to use, at low cost, securely and reliably, can wide popularization and application.
Description of the drawings
Fig. 1 is the functional block diagram of the utility model embodiment.
Specific implementation mode
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
With reference to figure 1, the novel 10KV ring main units cable vault damp-proof device of preferred the utility model, including photovoltaic
Component 1, accumulator 2,3, eight humidity sensors 4 of controller and three heaters 5, the heater 5 are patch type heater,
It is to be filled set on the indoor accumulator of ring main unit cable 2 that the solar photovoltaic assembly 1 wears ring main unit cable vault through insulated conductor
Electricity, the accumulator 2 through insulated conductor, power in order to control by device 3 and each heater 5, and three heaters 5 are respectively arranged on ring main unit
In the middle part of the inside top wall of cable vault, in the middle part of left part madial wall and on right part madial wall middle part, eight hygrosensors are set respectively
