Abstract
The utility model relates to a bus temperature detection device, which comprises a box body, a temperature sensor, a liquid crystal display screen and a dial switch, wherein the temperature sensor is arranged in a lower groove of each rectangular bus hole in a bus frame, and the measured temperature is transmitted to the box body through a signal line; a plurality of liquid crystal display screens for displaying the temperature of the bus are arranged on the end face of the box body; and a dial switch is arranged at the right lower part in the box body. When abnormal conditions occur, the device can send out pre-alarm information in various modes to prompt managers to pay attention to alarm points or take necessary measures. The utility model has the advantages of simple structure and scientific and reasonable design, with low costs, can realize remote detection, make managers make the exact judgement to unusual generating line, effectively improved the life-span of power supply quality and components and parts.
Description
Technical field
The utility model belongs to power domain, especially a kind of bus temperature pick-up unit.
Background technology
The high-tension switch cabinet at generating plant, alternating current station is important electric equipment.In equipment During Process of Long-term Operation, the positions such as the bus contact joint in switch cubicle, high-voltage cable joint cause resistance excessive because of aging or contact and generate heat, and make adjacent insulating element performance degradation, even puncture and cause the accident.According to statistics, there is quite a few relevant with heat problem in the reason that electric system has an accident.Therefore, must to adopt an effective measure monitoring bus temperature.Because the bus in switch cubicle is in high-voltage, often relatively and not all there is very high voltage between homophase, and structure is narrow and small, thermometric of cannot manually patrolling, so direct-detection high voltage bus temperature is a difficult problem in electric system detection always.
Through retrieval, find one section of patent documentation relevant to this patent content, publication number is the Chinese patent of CN203455090U, which discloses a kind of high voltage bus system for detecting temperature, comprises acquisition module, control module, communication module and host computer; Described acquisition module is connected with bus, for gathering bus temperature, and is transferred to described control module; Described control module is connected with acquisition module, for the bus temperature received is transferred to described host computer by described communication module, or processes the bus temperature received; Described communication module is connected with described control module, is transferred to host computer for the bus temperature described control module received.
By contrast, above-mentioned patent publication us Problems existing is: 1, the concrete numerical value of bus overtemperature can not show in real time; 2, because the bus in switch cubicle is more, specifically cannot judge that problem has appearred in which bus, accurately can not find problem points, extend servicing time.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of bus temperature pick-up unit, and this device, by the ruuning situation of Real-Time Monitoring bus temperature, can effectively prevent switch cabinet bus fault from occurring.
Scheme of the present utility model is achieved in that
A kind of bus temperature pick-up unit, comprise box body, temperature sensor, LCDs and toggle switch, described temperature sensor is arranged in the lower recess in each rectangular bus bar hole in bus frame, and the temperature recorded is transferred to box body by signal wire; The end face of described box body installs multiple LCDs for showing bus temperature; Right lower quadrant in described box body installs toggle switch.
And, described box body end face mounted LED lamp and alarming horn.
And RS485 terminal is installed in described box body one side.
And, in described box body, wireless communication module is installed.
Advantage of the present utility model and good effect are:
When there are abnormal conditions, this device can send pre-alarm information in many ways, and prompting managerial personnel tackle alarm set point and paid attention to or take necessary measure.The utility model structure is simple, design science is reasonable, cost is low, can realize remote detection, makes managerial personnel make correct judgement for abnormal bus, effectively improves the life-span of power supply quality and components and parts.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of temperature sensor in the utility model;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail.
A kind of bus temperature pick-up unit, as shown in Figure 1 and Figure 2, comprise box body 5, temperature sensor 3, LCDs 6 and toggle switch 11, the end face of described box body installs multiple LCDs for showing bus temperature, in the present embodiment accompanying drawing four, and longitudinal arrangement, the temperature of bus can be sent to transformer station in real time by liquid crystal display, it is convenient to read, and notes abnormalities and can take solution fast; Described temperature sensor is arranged in the lower recess in each rectangular bus bar hole 2 in bus frame 1, and the temperature recorded is transferred to box body by signal wire 4, and is shown by LCDs; Right lower quadrant in described box body installs toggle switch, multiple bus frame can be encoded by toggle switch, and object is convenient to the very first time to note abnormalities the particular location of bus frame, do not need investigation, the servicing time effectively shortened.
In the present embodiment, described box body end face mounted LED lamp 7 and alarming horn 8, when bus temperature is higher than the temperature value preset, LED can be given out light, and starts alarming horn simultaneously, effectively serves warning function.
Described box body one side is provided with the RS485 terminal 9 be connected with host computer (not shown).
Also install wireless communication module 10 in described box body, the temperature of bus can be sent on the mobile phone of transformer room managerial personnel or other staff by this wireless communication module in real time, and its effect improves safety coefficient.
The power supply of this device can take from L phase and the N phase of this TV station switch cubicle.
When there are abnormal conditions, this device can send pre-alarm information in many ways, and prompting managerial personnel tackle alarm set point and paid attention to or take necessary measure.The utility model structure is simple, design science is reasonable, cost is low, can realize remote detection, makes managerial personnel make correct judgement for abnormal bus, effectively improves the life-span of power supply quality and components and parts.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in embodiment; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
