Description

Moistureproof terminal box
Technical field:
The utility model relates to the terminal box in a kind of improved power transmission and transformation line, particularly a kind of moistureproof terminal box.
Background technology:
Existing terminal box all is made of the metal box of a band door, terminal board and the terminal established on set support, the support in it mostly, and they generally place the open air.The greatest problem humidity resistance that they in use exist is poor, and especially in China south, this kind situation is serious especially.The temperature difference is big, high humidity is China's south environmental quality, this kind phenomenon makes that the terminal screw rust in the terminal box is bad, terminal corrosion, cable are aging, insulation decline, secondary circuit problem with grounding between the terminal are frequent, security incident constantly, often causes outage or is forced to the maintenance that has a power failure, and has brought loss and inconvenience for the production of enterprise and people's life.Cause the problems referred to above cause to be that existing terminal box is poorly sealed, easily stuffy in water inlet and moisture, the case, moisture can not arranged, and terminal box top is prone to condensation.
Summary of the invention:
The purpose of this utility model is that at the deficiency of the existing in use existing humidity resistance difference of terminal box, and it is good to propose a kind of humidity resistance, can better solve the moistureproof terminal box of the existing existing problem of terminal box.
Can realize the purpose of this utility model by following technical proposals, a kind of moistureproof terminal box, comprise terminal board and the terminal established on support set in the casing, casing of band door, the support, it is characterized in that chamber door is provided with the sealing strip of rubber quality, terminal board top is provided with the condensation temperature controller, be provided with fresh air inlet on tank wall, the place is provided with heater at the chamber interior wall fresh air inlet, is provided with exhaust vent on tank wall, the place is provided with ventilating fan at the chamber interior wall exhaust vent, and case is built-in with the box body that holds hygroscopic agent; Be electrically connected between condensation temperature controller, heater, the ventilating fan.
For preventing that toy from piercing the initiation security incident from the perforate of casing institute, all perforate position inwalls all install anti-toy wire netting additional on the tank wall.
For preventing that rainwater is blown into or is splashed into from the perforate of casing institute, the outer wall at all perforate positions top all installs rain cover additional on the tank wall.
When preventing that in the winter time outside humidity is big with plum rains season, heater power is not enough and make the humidity after the decline still can not avoid the easiest humidity that makes the terminal corrosion, is provided with two groups of heaters in case, and is provided with and two groups of corresponding circuit of heater.
For ease of observing the situation of hygroscopic agent in the box body, the lid face that holds the hygroscopic agent box body is provided with inspection hole.
Effect of the present utility model is: 1, humidity resistance is good; eliminated that terminal box makes because of making moist that terminal screw rust is bad, terminal corrosion, problem that cable is aging; stop the potential safety hazards such as DC earthing that terminal box causes because of making moist and occurred, laid special stress on protecting the fastness of cable connection on the reliability of secondary circuit and the terminal board.2, good sealing effect has reduced the number of times of cleaning, maintenance, has reduced working strength of workers.3, prolonged the useful life of terminal box, prolonged 3-4 the useful life of comparable existing terminal box, this is that its inner part corrosion aging conditions greatly alleviates institute extremely.4, reduce unplanned frequency of power cut, guaranteed the safe and stable operation of electrical network.5, good in economic efficiency, can be enterprise and save a large amount of production costs, this is not only to have reduced the replacing of terminal box and various parts, and has reduced the power failure maintenance times.
Below in conjunction with embodiment and accompanying drawing the utility model is further set forth:
Description of drawings:
Accompanying drawing 1 is the utility model structural representation (broken section);
Accompanying drawing 2 is the circuit connection diagram between condensation temperature controller, heater, the ventilating fan in the utility model.
Embodiment:
Referring to accompanying drawing 1,2 one kind of moistureproof terminal box, it is mainly by terminal board and terminal, the condensation temperature controller 2 that establish on terminal board top, the heater of establishing on tank wall 3 and the ventilating fan 4 established on support set in the casing 1 of band door, the casing 1, the support, form at the built-in box body that holds hygroscopic agent 5 of case.Be electrically connected between condensation temperature controller 2, heater 3 and the ventilating fan 4.Ventilating fan 4 is located at set exhaust outlet place, casing 1 rear wall top.Heater 3 is located at the air inlet place of casing 1 lower sidewall.The air that enters casing 1 needs heater via 3 dehumidifying.The function of ventilating fan 4 is the aqueous vapor that heater 3 heating backs are produced is discharged outside the casing 1.Air humidity in 2 pairs of casings of condensation temperature controller 1 is monitored, and when air humidity reaches condensation temperature controller 2 action set points, then starts 3 pairs of terminal boxs of heater and carries out the dehumidifying dehumidifying and start ventilating fan 4 hydrofuge outwardly simultaneously.For preventing that the outer water of casing 1, dust etc. from entering in the casing 1, the chamber door of casing 1 is provided with the sealing strip of rubber quality.The lid face of the box body 5 of hygroscopic agent is provided with inspection hole, and its function is the situation of checking hygroscopic agent in the box, in the box body 5 of hygroscopic agent changeable colour silicon is housed, and its function is for keeping casing 1 interior air drying and being convenient to check.For preventing that toy institute's perforate from casing 1 wall from piercing the initiation security incident, all perforate position inwalls all install anti-toy wire netting 6 additional.For preventing that rainwater institute's perforate from casing 1 wall is blown into or is splashed into, all outer wall tops, perforate position all install rain cover 7 additional.Accompanying drawing 2 circuit diagrams are when outside humidity is big with plum rains season in the winter time, heater 3 power are not enough and set when making humidity after the decline can not avoid the easiest humidity that makes the terminal corrosion, it is provided with two heaters 3 (ordinary circumstance is divided into and got final product), and condensation temperature controller 2, heater 3, ventilating fan 4 are electrically connected by the transducer contact 9 that three one poles exchange air switch 8 and condensation temperature controller 2.
