Abstract
The current contact box can not monitor the temperature of the moving contact and the static contact in the operation at any time and any place, and can not effectively prevent accidents in time. The utility model provides a contact box with temperature measuring device comprises the contact box main part, and its characteristics are equipped with the temperature cylinder on the contact box body, are equipped with the full skirt at the temperature cylinder inner wall of temperature cylinder and contact box body link, are equipped with temperature sensor in the temperature cylinder other end, and temperature sensor is connected with the temperature monitor electricity. The utility model discloses can be used to among the high-pressure handcart-type switchgear of various models, replace current various contact boxes, reach the purpose that moves in the online monitoring contact box at any time, static contact temperature to move in the contact box to the individual high temperature, the static contact carries out in time maintenance or change, effectively prevents the emergence of accident. The utility model has the advantages of simple structure, low cost, easy implementation, convenient use, safety, reliability and the like, and has popularization value.
Description
Technical field
The utility model relates to the improvement of contact box, is a kind of contact box with temperature measuring equipment specifically, belongs to the parts in the electrical control equipment.
Background technology
Contact box is an insulating element commonly used in the 6-35 kilovolt high-tension switch cabinet, is installed in wherein dynamic and static contact in the work owing to reasons such as cooperations very easily produce distortion or loose contact, causes the contact site temperature to raise, and for a long time overheatedly will cause serious accident.So in the high-tension switch cabinet temperature that can monitor dynamic and static contact in the contact box at any time in service, be very necessary, but present contact box all can not be monitored the temperature of dynamic and static contact in its contact box in service whenever and wherever possible.The staff can only be when power failure be safeguarded, blindly frequent each contact box of maintenance, the situation of checking dynamic and static contact surface coating and moving contact spring one by one one by one.Therefore, can not trouble-saving timely and effectively generation.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, provide a kind of simple in structure, can on-line monitoring a kind of contact box of dynamic and static contact temperature in the contact box with temperature measuring equipment.
The purpose of this utility model is achieved in that
This contact box with temperature measuring equipment, constitute by the contact box main body, be characterized on the contact box box body, being provided with thermal bulb, thermal bulb inwall at thermal bulb and contact box box body link is provided with full skirt, in the thermal bulb other end temperature sensor is housed, temperature sensor is electrically connected with temperature indicator.
In temperature indicator, also can be added with alarm, send the alarm signal when temperature of dynamic and static contact reaches certain limiting value in contact box; Between full skirt and temperature sensor, also can be added with the insulating protection sheet, prevent the electromagnetic interference of strong-electromagnetic field temperature sensor.
The utility model is simple in structure, and those skilled in the art can be selected existing withstand voltage fire proofing and electric components such as commercially available specific temperature sensor, temperature display alarm easily for use, and adopts conventional processes to make, and implements easily.
The utility model can be used in the high pressure handcart-type switch equipment of various models, replace existing various contact box, reach online purpose of monitoring dynamic and static contact temperature in the contact box at any time, so that only the dynamic and static contact in the too high contact box of indivedual temperature is repaired or replaced, thereby the accident that prevents timely and effectively takes place.Have simple in structure, cost is low, easy enforcement, advantage such as esy to use, safe and reliable, has promotional value.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Among the figure: 1 bus, 2 fixed contacts, 3 moving contacts, 4 acting arm conducting rods, 5 contact box box bodys, 6 thermal bulbs, 7 full skirts, 8 infrared temperature sensors, 9 signal transmssion lines, 10 display controllers, 11 protective sheet.
Embodiment
The utility model is further described with the embodiment that provides below in conjunction with accompanying drawing.
With reference to accompanying drawing, this contact box with temperature measuring equipment constitutes the contact box main body by bus 1, fixed contact 2, moving contact 3, acting arm conducting rod 4, contact box box body 5 etc., on the contact box box body, be provided with thermal bulb 6 with contact box box body one, on the thermal bulb inwall of thermal bulb and contact box box body link, be provided with full skirt 7, infrared temperature sensor 8 is housed in the thermal bulb other end, infrared temperature sensor is electrically connected with display controller 10 through signal transmssion line 9, and plastics protective sheet 11 is housed between full skirt and the infrared temperature sensor in thermal bulb.
The utility model designer presses embodiment, implement one 10 kilovolts contact box with temperature measuring equipment, IRTP300M type infrared ray sensor is housed in the thermal bulb of contact box and, realizes online monitoring dynamic and static contact temperature in the contact box with after BDC100 type display controller is electrically connected.Internal simulation experiment shows, but this contact box online at any time with temperature measuring equipment monitor in the contact box-variations in temperature of 30-300 ℃, satisfactory for result.
