Abstract
The utility model relates to a high-voltage switch cabinet of a transformer substation, particularly to a temperature indicator in a switch cabinet. The temperature indicator comprises a bimetallic sheet (1), a temperature pointer (2), a temperature panel (3) and a wiring board (4). To be specific, the bimetallic sheet (1) is installed in the temperature panel (3) in a spiral rolling mode; the temperature pointer (2) is arranged at the surface of the temperature panel (3); and the wiring board (4) is arranged at the side of the temperature panel (3). The outer side end of the bimetallic sheet (1) is connected with the wiring board (4) and the inner side end is connected with the temperature pointer (2); and the bimetallic sheet (1) is formed by mutual contact of an active layer with the large thermal expansion coefficient and a passive layer with the small thermal expansion coefficient. When the equipment heats, the temperature pointer indicates the rising of the temperature of the equipment; there is no need to add any battery as the energy and an objective of alarming for temperature abnormity of the high-voltage equipment is achieved. The temperature indicator with the simple structure can be implemented conveniently; and the production cost and the operating cost are low.
Description
Technical field
The utility model relates to transformer station's high-tension switch cabinet, is specifically related to temperature indicator in a kind of switch cubicle.
Background technology
Electric equipment, in During Process of Long-term Operation, because of problems such as aging, loosening, mounting process, overload operations, causes the connecting portion contact resistance to increase, persistent fever when through-flow, and temperature constantly rises.If overheated high-temperature situation is not found, take measures, will be had a huge impact performance and the equipment life of insulating part, will cause the equipment scaling loss when serious, even cause more major break down.In recent years, similarly the accident generation is a lot of, and blast on fire has caused fire and large-area power outage, has caused a large amount of property losses.For this problem, current also have a testing tool such as infrared radiation thermometer, but in the face of the switch cubicle of sealing helpless; Temperature display wax sheet is also the product that is applied to the earliest electric equipment joint thermometric, when temperature display wax sheet is pasted place's surface temperature higher than specified fusion temperature, temperature display wax sheet can automatically melt and come off, and it is overheated herein to mean, but can't reuse, cause the inconvenience of again installing; Also have in addition the switch cubicle temp measuring system, can realize device measuring in cabinet and teletransmission, but it involves great expense, be not easy to comprehensively universal.
The utility model content
The purpose of this utility model is to provide temperature indicator in a kind of switch cubicle, has solved the problem that the temperature measuring equipment of current switch cubicle can't reuse and involve great expense.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
Temperature indicator in a kind of switch cubicle, be arranged on the high voltage electric equipment in switch cubicle, comprise bimetal leaf, temperature pointer, temperature panel and terminal block, wherein said bimetal leaf is the spiral web-like and is arranged in the temperature panel, described temperature pointer is arranged on the surface of temperature panel, described terminal block is arranged on the side of temperature panel, the outboard end of described bimetal leaf connects terminal block, medial end connects temperature pointer, and the passive layer that the active layers that described bimetal leaf is large by thermal coefficient of expansion and thermal coefficient of expansion are little mutually is close to and is formed.
Further technical scheme is, described active layers is in the curling outside, and passive layer is in curling inboard.
Further technical scheme is, described temperature panel is provided with scale or the warning color be complementary with temperature pointer.
Compared with prior art, the beneficial effects of the utility model are: be directly installed on the high voltage electric equipment in switch cubicle, when equipment heating, temperature pointer indicating equipment temperature raises; Must balancing cell as the energy, reach the purpose of Temperature Monitoring of HV Apparatus abnormal alarm; Simple in structure, be convenient to implement, production cost and operating cost are lower.
The accompanying drawing explanation
The cut-away view that Fig. 1 is temperature indicator in the utility model switch cubicle.
The normal temperature view that Fig. 2 is an embodiment of temperature indicator in the utility model switch cubicle.
The condition of high temperature schematic diagram that Fig. 3 is an embodiment of temperature indicator in the utility model switch cubicle.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 shows an embodiment of temperature indicator in the utility model switch cubicle: temperature indicator in a kind of switch cubicle, be arranged on the high voltage electric equipment in switch cubicle, comprise bimetal leaf 1, temperature pointer 2, temperature panel 3 and terminal block 4, wherein said bimetal leaf 1 is the spiral web-like and is arranged in temperature panel 3, described temperature pointer 2 is arranged on the surface of temperature panel 3, described terminal block 4 is arranged on the side of temperature panel 3, the outboard end of described bimetal leaf 1 connects terminal block 4, medial end connects temperature pointer 2, the active layers that described bimetal leaf 1 is large by thermal coefficient of expansion and the little passive layer of thermal coefficient of expansion mutually are close to and are formed.
According to another embodiment of temperature indicator in the utility model switch cubicle, described active layers is in the curling outside, and passive layer is in curling inboard.
According to another embodiment of temperature indicator in the utility model switch cubicle, described temperature panel 3 is provided with scale or the warning color be complementary with temperature pointer 2.
The utility model is mainly the characteristic of having utilized bimetal leaf, because the thermal coefficient of expansion of active layers and passive layer is different, when variations in temperature, the deformation of active layers is greater than the deformation of passive layer, thereby the integral body of bimetal leaf 1 will be to the passive layer curving, thereby the curvature of this composite material changes and produces deformation, temperature pointer 2 on temperature panel 3 rotates along with inner bimetal leaf 1 deformation, as shown in Figures 2 and 3, warning staff Temperature Monitoring of HV Apparatus raises, and should process in time.
Claims (3)
1. temperature indicator in a switch cubicle, be arranged on the high voltage electric equipment in switch cubicle, it is characterized in that: comprise bimetal leaf (1), temperature pointer (2), temperature panel (3) and terminal block (4), wherein said bimetal leaf (1) is the spiral web-like and is arranged in temperature panel (3), described temperature pointer (2) is arranged on the surface of temperature panel (3), described terminal block (4) is arranged on the side of temperature panel (3), the outboard end of described bimetal leaf (1) connects terminal block (4), medial end connects temperature pointer (2), the active layers that described bimetal leaf (1) is large by thermal coefficient of expansion and the little passive layer of thermal coefficient of expansion mutually are close to and are formed.
