Abstract
The utility model discloses a protective cover for a dry-type transformer. The protective cover comprises a shell (1) and a skeleton (2) for supporting the whole shell, wherein a door (7) is arranged on the front side of the shell (1); an electromagnetic lock (8) is arranged on the door (7); observation windows (3) are formed in the left and right sides of the door (7); noise detection equipment (4) and temperature control equipment (5) are arranged below the observation windows (3) respectively; a plurality of fans (9) are arranged at the top of the shell (1); low-voltage outlet windows (6) are formed in the left and right sides of the shell (1) respectively. According to the protective cover for the dry-type transformer, a signal is transmitted to the temperature control equipment through a wire by a temperature sensor in a winding of the dry-type transformer, a temperature range is preset by a user, and when the temperature of the transformer is higher than the temperature range, a signal is transmitted through the temperature control equipment, and the fans are turned on for radiation, so that the service life of the transformer is prolonged.
Description
Technical field
The utility model relates to power distribution equipment field, is specifically related to a kind of dry-type transformer protective cover.
Background technology
At present, in power distribution field,, the requirement to environmental protection, the aspect of performance such as energy-conservation to the increasing of electric network reconstruction dynamics and user along with country, dry-type transformer product is popularized widely and is applied on market.Dry-type transformer is mainly used in moving on-the-spot security protection with protective cover, avoids causing interruption of service because the foreign matters such as toy enter, and can effectively protect personal safety and play certain electromagnetic shielding action.At present, for safety and consideration attractive in appearance, when user orders dry-type transformer, General Requirements configuration containment envelope.Dry-type transformer generally includes base, side plate and the top board of being made by shaped steel with protective cover, side plate is provided with door leaf.Transformer people in the process of operation can only detect the operation of transformer by observation window, general electrician can not judge that whether transformer is in misoperation according to the operation sound of transformer, and cannot obtain easily the temperature of transformer, thereby cannot determine whether manually to open cooling fan.
Utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of and can detect noise and temperature control the protective cover to dry-type transformer intelligent cooling.
The technical solution adopted in the utility model is such: the skeleton 2 that comprises shell 1 and the whole shell of support, the front side of its housing 1 is provided with door 7, on door 7, electromagnetic lock 8 is housed, the right and left of door 7 has observation window 3, the noise measuring equipment 4 that is respectively equipped with below and the temperature control device 5 of observation window 3, shell 1 top is provided with several fans 9, and the left and right sides of shell 1 is respectively equipped with low-pressure line-outgoing window 6.
Further, the power line of fan 9 is connected with temperature control device 5 by wire.
Further, the power supply of noise measuring equipment 4 and temperature control device 5 is taken from step-down side.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, the utility model sends signal by the temperature sensor being placed in dry-type transformer winding, signal is sent on temperature control device by wire, user sets in advance temperature range, when the temperature of transformer higher than a point range is, temperature control device sends signal, and connect fan and dispel the heat, thereby increased useful life of transformer.
2, the utility model is monitored the running noises of transformer by noise measuring equipment, when transformer noise surpasses preset value, noise measuring equipment sends signal to control room, and give the alarm, thereby avoided because electrician does not notice that two make continuous service under the abnormal conditions of transformer.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1; a kind of dry-type transformer protective cover; the skeleton 2 that comprises shell 1 and the whole shell of support; the front side of its housing 1 is provided with door 7; on door 7, electromagnetic lock 8 is housed, the right and left of door 7 has observation window 3, the noise measuring equipment 4 that is respectively equipped with below and the temperature control device 5 of observation window 3; shell 1 top is provided with several fans 9, and the left and right sides of shell 1 is respectively equipped with low-pressure line-outgoing window 6.
Further, the power line of fan 9 is connected with temperature control device 5 by wire.
Further, the power supply of noise measuring equipment 4 and temperature control device 5 is taken from step-down side.
In actual use, by the temperature sensor being placed in dry-type transformer winding, send signal, signal is sent on temperature control device 5 by wire, user sets in advance temperature range, when the temperature of transformer higher than a point range is, temperature control device sends signal, and connects fan 9 and dispel the heat, thereby has increased the useful life of transformer.
By noise measuring equipment 4, the running noises of transformer is monitored, when transformer noise surpasses preset value, noise measuring equipment sends signal to control room, and gives the alarm, thereby has avoided because electrician does not notice that two make continuous service under the abnormal conditions of transformer.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
