Description

Antifreeze distribution box
Technical field
The utility model relates to a kind of distribution box, and more particularly, it relates to a kind of antifreeze distribution box that can use under harsh climate.
Background technology
Distribution box sub-power distribution box and light distribution box, batch meter are the final stage device of distribution system.Distribution box is the general designation of motor control center.Distribution box is used in the occasion that duty ratio is comparatively disperseed, loop is less; Motor control center is used for the occasion that load is concentrated, loop is more.They give load nearby the power distribution of a certain for upper level controller switching equipment circuit.This grade of equipment reply load provides protection, monitoring and controlling.
At present, the distribution box on market, comprises casing and chamber door.Although this distribution box can both normally use in most environment, but under harsh climate, particularly outdoor, distribution box surrounding easily causes accumulated snow, when needs are to when in distribution box, circuit overhauls, often because of the situation that accumulated snow causes chamber door not opened, and chamber door and casing freeze mutually, not only do not open door, and because reason of freezing causes distribution box bursting by freezing to damage.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of antifreeze distribution box that normally can use under harsh climate.
For achieving the above object, the utility model provides following technical scheme: a kind of antifreeze distribution box, it comprises casing and chamber door, described door opening or closing is in described casing, described chamber door is provided with interlayer, is provided with heater in described interlayer, and described heater comprises the conductive fluid stored in interlayer, be soaked with heating element in described conductive fluid, described heating element is electrically connected with power supply and temperature detect switch (TDS).
By adopting technique scheme, when ambient weather is cold, distribution box surrounding causes accumulated snow to freeze, when needing to overhaul distribution box internal circuit, because the opening and closing of chamber door is all in casing, distribution box surrounding accumulated snow can not be opened chamber door and have an impact, in addition temperature detect switch (TDS) can control heater according to surrounding environment and heats, then casing and chamber door can not freeze, then can overhaul circuit by smooth opening chamber door, avoid casing and chamber door simultaneously and to freeze the damage caused.
The utility model is set to further: described casing is cylindrical, and described chamber door is circular arc, and described chamber door is connected with casing slippage, and the tank wall being contained in casing in described chamber door slipping is inner.
By adopting technique scheme, when chamber door slippage is opened, chamber door is at box house, and around distribution box, accumulated snow is opened can not have an impact to chamber door.
Further: described power supply comprises battery, the inwall of described chamber door is provided with power pack, and described battery is located in power pack.
By adopting technique scheme, arranging of power pack facilitates power supply to be finished rear replacing power supply, achieves long-time utilization.
Further: described temperature detect switch (TDS) is placed on chamber door side.
By adopting technique scheme, temperature detect switch (TDS) institute temperature sensor is aperture temp between casing and chamber door, and it is more accurate to measure, avoid because the temperature difference at gap and all the other positions cause add heat waster or postpone heating problems.
Further: described heater can arrange many groups.
By adopting technique scheme, many group heaters can improve the firing rate of chamber door, and the multiple temperature detect switch (TDS)s be simultaneously connected with more fully can measure problem.
Compared with prior art, the utility model has the advantage of: the door structure of different distribution box in the past can not normally use under severe cold condition, design is a kind of from receipts type heating chamber door, can solve this technical problem, distribution box also can normally be used under severe cold condition.

Embodiment
Referring to figs. 1 through Fig. 4, the antifreeze distribution box embodiment of the utility model is described further.
See Fig. 1 to 2, a kind of antifreeze distribution box, it comprises casing 1 and chamber door 2, the opening and closing of described chamber door 2 is in described casing 1, described chamber door 2 is provided with interlayer, is provided with heater 21 in described interlayer, and described heater 21 comprises the conductive fluid stored in interlayer, be soaked with heating element in described conductive fluid, described heating element is electrically connected with power supply 216 and temperature detect switch (TDS) 211.
The present embodiment preferably conductive fluid is water 214, and heating element is electrical heating wire 213, and temperature detect switch (TDS) is that closed 10 degree of KSD301 temperature detect switch (TDS) 0 degree disconnects thermostat.
When ambient weather is cold, distribution box surrounding causes accumulated snow to freeze, when needing to overhaul distribution box internal circuit, because chamber door 2 is opened form and is adopted from receipts type, distribution box surrounding accumulated snow can not be opened chamber door 2 and have an impact, and chamber door 2 can heat lower than when less than 0 degree at temperature in addition, then casing 1 and chamber door 2 can not freeze, then can overhaul by smooth opening chamber door 2 pairs of circuit, avoid casing 1 and chamber door 2 simultaneously and to freeze the damage caused.
Chamber door 2 and casing 1 are slidably connected, and electrical heating wire 213 is dipped in water 214, and wire 212 is placed in water 214 and the material between chamber door 2 wall and water 214, and temperature detect switch (TDS) 211 is fixing with on chamber door 2 sidewall, and power supply 216 box 215 is fixing with on chamber door 2 inwall.
See Fig. 3, electrical heating wire 213 and temperature detect switch (TDS) 211, power supply 216 are in series by wire 212.Temperature detect switch (TDS) 211 closes, and circuit turn-on, electrical heating wire 213 heats.
See Fig. 4, chamber door 2 is flexibly connected with casing 1, and chamber door 2 is in circular arc, and casing 1 is cylindrical, and the switch of chamber door 2 can close at casing 1 inside certainly, does not take the space outside casing 1.
For ensureing that this distribution box also can normally use under severe cold condition, casing 1 top is probably long-pending a large amount of snow, and comparatively large to casing 1 pressure, therefore casing 1 needs by intensity larger, the harder material of hardness is made, can be made with iron, chamber door 2 adopts iron to be made equally, and pulley can be adopted between chamber door 2 with casing 1 to be connected, structure is simple, practical, consider the precise control of temperature detect switch (TDS) 211, advise that temperature detect switch (TDS) 211 used adopts electronic temperature controller.
It should be noted that: described chamber door 2 is opened and chamber door 2 also can be adopted to be rolling screen door forms from receipts form herein, but consider easy for installation, manufacturing cost factor, preferably select chamber door 2 in circular arc, casing 1 is cylindrical, and chamber door 2 and casing 1 are slidably connected this scheme.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
