Abstract
The utility model provides a heat-to-dehumidify terminal box, which comprises a box body, a top cover arranged at the top of the box body, and a lower heater arranged at the middle and lower part of the interior of the box body. The top cover is internally provided with an upper heater opposite to the lower heater. A temperature sensor positioned at the lowest-temperature location and connected with the upper and lower heaters is arranged in the box body. The top cover is composed of an outer cover body and an inner cover body arranged in the outer cover body. A condensation cavity is formed between the outer cover body and the inner cover body. The inner cover body is provided with a moisture discharging hole for communicating the interior of the box body with the condensation cavity. A suction fan is arranged in the moisture discharging hole. A condensation screen is arranged in the condensation cavity. The bottom of the outer cover body is provided with a breathing hole for communicating the outside with the condensation cavity. Due to the adoption of the upper and lower heaters, both the temperature difference between inside and outside, and the internal temperature difference, are lowered. Therefore, the condensation inside the box body is avoided and moistures inside the box body are discharged to the outside.
Description
Technical field
The utility model relates to a kind of terminal box.
Background technology
Known, terminal box mainly comprises casing, be arranged on the top cover at casing top, be arranged at the terminal support in casing and binding post on terminal support is set, terminal box is arranged at outdoor environment usually, there was dampness in the air or the condition such as temperature decrease under, especially in rainy season, box house is humidity, condensation and ponding easily, casing makes moist terminal board screw and brace is got rusty, make the secondary terminals loose contact, can make even open circuit of current transformer terminal heating, cause protection tripping or malfunction, cause accident; The instrument transformer voltage that causes and switch, the temperature signal termination contact of making moist is bad, can cause observing and controlling, protective device operation exception, mistaking signal, causes the operations staff to judge the disconnected error analysis of making by accident.Have in the market various moistureproof schemes for the problems referred to above, commonly used is that damp mode is driven in heating, but be used for driving the centre position that damp heater is arranged at terminal box usually in existing terminal box, the layout of heater can't make the temperature in terminal box evenly distribute, and may produce condensation at the temperature lower position when serious.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and damp terminal box is driven in the heating that provides a kind of box house to have a narrow range of temperature.
The purpose of this utility model realizes by following technical solution:
Damp terminal box is driven in a kind of heating, comprise casing, be arranged at the top cover at casing top, it is characterized in that: the position, middle and lower part in described casing is provided with lower heater, be provided with the upper heater relative with lower heater in described top cover, be provided with in described casing and be positioned at the temperature sensor that the temperature extreme lower position is connected with upper and lower heater.
Further, described top cover is comprised of outer cover and the interior lid that is arranged in outer cover, formation condensation chamber between outer cover and interior lid, offer the weep hole that is communicated with box house and condensation chamber on interior lid, be provided with air exhauster on weep hole, be provided with the condensation net in the condensation chamber, described outer cover bottom offers and is communicated with spiracle outside and the condensation chamber.
Further, described interior lid is spliced by first, second swash plate and the biside plate that are in tilted layout, and the first swash plate is greater than the second swash plate, and described condensation net is arranged at the upper surface of the first swash plate, and described upper heater is arranged at the lower surface of the second swash plate.
Further, the intersection of described first, second swash plate is formed with the hydrofuge gap that is communicated with box house and condensation chamber.
Further, described lower heater comprises two that arrange the lateral separation, and corresponding described upper heater also is two of lateral separation arrangement.
Further, described upper and lower heater is plate heater.
Further, be provided with in described casing for the mounting rail that lower heater is installed, described lower heater is fixedly mounted on mounting rail.
Further, described temperature sensor is arranged at the bottom of box inside.
The purpose of this utility model realizes by following technical solution:
Heater and the temperature sensor that is connected with heater are set in casing, temperature sensor is arranged on the minimum position of temperature in casing, namely with the position of the outside temperature difference maximum of casing, when the temperature of the detection of temperature sensor is reduced to preset value, heater is started working, reduce the casing internal-external temperature difference, stop the water in air molecule and condense in casing; Upper and lower heater is set in casing, can makes the box house uniformity of temperature profile, prevent from existing in casing low temperature dead angle generation condensation, can reduce internal-external temperature difference and internal difference in temperature by upper and lower heater, thereby stop internal condensation, expeling inner moisture.
top cover is by interior, outer cover forms, in, formation condensation chamber between outer cover, during work, air exhauster is introduced the moisture in casing in the condensation chamber, moisture condenses into water droplet after running into the condensation net, final water droplet is outside through spiracle discharge casing, less and be provided with respirator due to spiracle, therefore, outside moisture is difficult to from spiracle enters the condensation chamber, even entering the condensation chamber still can be processed into liquid by the condensation net and discharge, guarantee the sealing of casing, prevent that moisture from entering in casing by the hydrofuge passage, cut off replenishing of box house moisture from the source, effectively improve the moisture effect of terminal box.
Interior lid is spliced by first, second swash plate and biside plate, and the bootable drop that condenses of first, second swash plate that is in tilted layout converges downwards and finally flows to spiracle, is conducive to the discharge of liquid in the condensation chamber.
