Abstract
The utility model discloses a high-voltage cable distribution box having dehumidification and heat dissipation functions. The high-voltage cable distribution box comprises a box body (1), a wire inlet sleeve (2) and a circuit breaker (3), wherein the wire inlet sleeve (2) and the circuit breaker (3) are arranged inside the box body (1), the wire inlet sleeve (2) is connected with the circuit breaker (3) through an isolating switch, a dehumidification and heat dissipation device (6) is arranged inside the box body (1), a heat dissipation hole (4) is arranged on the upper portion of the box body (1), and a vent hole (5) is arranged at the lower end of the box body (1). The high-voltage cable distribution box has the advantages that an electric fan is added inside the cable distribution box, when a sensor senses that the temperature or the humidity inside the box is too high, the electric fan is turned on to blow wind into the box and reduce the temperature or conduct dehumidification, and the cable distribution box is simple in structure and reasonable in arrangement.
Description
Technical field
The utility model relates to a kind of cable distribution box, particularly relates to a kind of High-Voltage Cable Branching Case with dehumidifying heat sinking function.
Background technology
Cable distribution box is that a kind of being used for implemented tap, branch, continued and the equipment of change-over circuit cable line; It is divided into two big types by electric formation: one type is not contain any switchgear; Only have pair cable socket to handle and the annex that is connected in the casing, relatively simple for structure, volume is less; Function is more single, can be described as common distribution box; Another kind of is the annex that common distribution box is not only arranged in the case, also contains one or more switchgear, and its structure is comparatively complicated, and volume is bigger, and interface unit is many, and the manufacturing technology difficulty is big, and cost is high, can be described as senior distribution box.Though no matter common or senior distribution box all is closed; But be applied to the accident that distribution box is still too high through regular meeting's appearance temperature or humidity causes too greatly of high humility region; And the distribution of existing cable distribution box internal components is very unreasonable, can't satisfy the requirement of high voltage power transmission.
The utility model content
The purpose of the utility model is to overcome the shortcoming and defect of above-mentioned prior art, and a kind of simple and reasonable High-Voltage Cable Branching Case with dehumidifying heat sinking function is provided, and solves existing cable distribution box heat dispersion difference that has and the defective that can't dehumidify.
The purpose of the utility model realizes through following technical proposals: the High-Voltage Cable Branching Case with dehumidifying heat sinking function; Comprise casing and the entrance bushing and the circuit breaker that are arranged in the casing; Described entrance bushing is connected to circuit breaker through an isolating switch; Described box house also is provided with a dehumidifying radiator, and the top of casing is provided with louvre, and its lower end is provided with ventilation hole.
The control end of described dehumidifying radiator is connected with a temperature sensor and a humidity sensor.
Described dehumidifying radiator is an electric fan.
Be connected with an earthed switch on the described circuit breaker.
Be provided with a current transformer between described circuit breaker and the earthed switch.
The beneficial effect of the utility model is: in cable distribution box, increase an electric fan; When sensor sensing was too high to the temperature inside the box or humidity, electric fan promptly was unlocked, to drying in the case; Lower the temperature or dehumidify, and the utility model also has simple in structure, rationally distributed advantage.
Description of drawings
Fig. 1 is the external structure sketch map of the utility model;
Fig. 2 is the internal circuit configuration sketch map of the utility model;
Among the figure, 1-casing, 2-entrance bushing, 3-circuit breaker, 4-louvre, 5-ventilation hole, the 6-radiator that dehumidifies.
Embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the structure of the utility model is not limited only to following examples:
[embodiment]
Like Fig. 1, shown in Figure 2; High-Voltage Cable Branching Case with dehumidifying heat sinking function; Comprise casing 1 and the entrance bushing 2 and circuit breaker 3 that are arranged in the casing 1, described entrance bushing 2 is connected to circuit breaker 3 through an isolating switch, and described casing 1 inside also is provided with a dehumidifying radiator 6; The top of casing 1 is provided with louvre 4, and its lower end is provided with ventilation hole 5.
Described dehumidifying radiator 6 is an electric fan, and its control end is connected with a temperature sensor and a humidity sensor.
Be connected with an earthed switch on the described circuit breaker 3, and be provided with a current transformer between circuit breaker 3 and the earthed switch.
The operation principle of this device: the cable of an end is connected on the entrance bushing 2 after getting in the casing 1; The cable of the other end gets into casing 1 and is connected on circuit breaker 3, connects and disconnection through circuit breaker 3 may command two end cables, when anomaly occurring; But the isolating switch automatic disconnection, protection circuit safety; Temperature sensor senses in the casing 1 promptly transmits a signal to electric fan when the temperature inside the box reaches boundary or humidity sensor and senses the interior humidity of case and reach boundary, promptly starts electric fan and is dried in casing 1 inside, can lower the temperature and dehumidify.
Claims (5)
