Description
technical field:
The utility model relates to a kind of anti-condensation device for cable ring-system cabinet, feeder pillar.
background technology:
The anti-condensation performance of the controller switching equipments such as cable ring-system cabinet, feeder pillar is one of main performance index evaluating ring main unit.Due to gathering for a long time with under the continuous hot phase interaction produced in cable vault of moisture, ring main unit, feeder pillar easily produce dew condensation phenomenon, the harm of its condensation: (1) makes the insulating element of electric equipment make moist, decreasing insulating; (2) make the metal surface of electric equipment electro-chemical reaction can occur, make the equipment original paper in electronic product produce internal fault; (3) electrochemical reaction liberated heat simultaneously, long term, at bakelite, the insulating material such as epoxy resin can make material aging aggravate, lose insulating property in advance, therefore, the aging acceleration of cable accessory can be caused, cause the faults such as equipment burnout time serious, cause the problems such as the potential safety hazard of equipment.
At present, the anti-condensation employing temperature relay of cable ring-system cabinet, feeder pillar, humidity relay assembly serial connection heating arrangement, starts according to the dewpoint temperature under current humidity the formation that firing equipment prevents condensation.But because some areas (as the Northwest) day and night temperature is larger, under the environment closed, ring main unit, feeder pillar internal heat are distributed slower than outside, in addition its shell mostly is steel plate making, when indoor temperature does not also meet condensation-preventing device entry condition, ring main unit inwall condensation is formed, therefore existing anti-condensation equipment can not prevent device interior condensation from being formed, still exist and cause the problems such as the potential safety hazard of equipment.
summary of the invention:
In order to overcome prior art Problems existing, the utility model provides a kind of anti-condensation device for cable ring-system cabinet, feeder pillar, and structure is simple, easy to use, thoroughly can solve the condensation problem of cable ring-system cabinet and feeder pillar.
For solving the problems of the technologies described above, the utility model takes following technical scheme:
For the anti-condensation device of cable ring-system cabinet, feeder pillar, comprise voltage transformer pt, time controller and electro-heat equipment, be power supply by voltage transformer pt in cable ring-system cabinet, feeder pillar, be connected on time controller, time controller and electro-heat equipment are serially connected.
The voltage that voltage transformer pt in above-mentioned cable ring-system cabinet, feeder pillar exports is alternating voltage 220V.
Above-mentioned time controller can set 6 ~ 8 time periods according to seasonal variations.
Above-mentioned electro-heat equipment adopts the electric heating lamp of 245 ~ 275W, replaceable.
Anti-condensation device of the present utility model utilizes the voltage transformer (VT) residual capacity in cable ring-system cabinet to be power supply, according to the time of condensation condensation under Various Seasonal, especially for the situation analysis that the Northwest's day and night temperature is larger, the different time sections of setting condensation condensation, the start-up time of regulating time controller, electro-heat equipment dispels the heat, improve ring main unit internal temperature, ensure that internal temperature is greater than external temperature, before condensation is not formed, destroy the meteorological condition that condensation is formed, thus prevent the generation of condensation.
The beneficial effects of the utility model: (1) this be used for cable ring-system cabinet, feeder pillar anti-condensation device structure simple, easy to use, under not influential system normal operation, thoroughly can eliminate the condensation in cable ring-system cabinet, feeder pillar and frost, guarantee the safety of equipment and the person; (2) this condensation device utilizes the voltage transformer (VT) residual capacity in cable ring-system cabinet to be power supply, with low cost, and easily, security is good, and distribution operation maintenance personnel can be installed through simple training, can be applicable at distribution network system in assembling.
accompanying drawing illustrates:
fig. 1 is the circuit diagram of the utility model for the anti-condensation device of cable ring-system cabinet, feeder pillar.
In figure: 1-voltage transformer pt, 2-time controller, 3-electro-heat equipment.
embodiment:
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1, for the anti-condensation device of cable ring-system cabinet, feeder pillar, comprise voltage transformer pt 1, time controller 2 and electro-heat equipment 3, in cable ring-system cabinet, feeder pillar, pass through voltage transformer pt 1 is power supply, be connected on time controller 2, time controller 2 and electro-heat equipment 3 are serially connected; The voltage that voltage transformer pt 1 in described cable ring-system cabinet, feeder pillar exports is alternating voltage 220V; Described time controller 2 can set 6 ~ 8 time periods according to seasonal variations; Described electro-heat equipment 3 adopts the electric heating lamp of 245 ~ 275W, can change.
This condensation device is installed in 10kv cable ring-system cabinet, utilize voltage transformer pt residual capacity in cable ring-system cabinet as power supply, according to the time of condensation condensation under Various Seasonal, the different time sections of setting condensation condensation, the start-up time of regulating time controller, electro-heat equipment dispels the heat, improve ring main unit internal temperature, ensure that internal temperature is greater than external temperature, the meteorological condition that condensation is formed was destroyed before condensation is not formed, thus the condensation thoroughly eliminated in cable ring-system cabinet and frost, ensure that the safety of equipment and the person.
