A solid-sealed polar pole main body is injected with an upper contact temperature sensing unit and a lower contact temperature sensing unit; a handcart contact temperature on-line monitoring temperature sensing unit is combined with the solid-sealed polar pole structure into one; a thermal detector is directly contacted with a switch equipment handcart moving contact, the measuring part is accurate and the measuring temperature is accurate; in addition, an induction power supply coil is adopted to supply power, so that the conditions that the battery is changed due to power off and the temperature measurement is influenced by reduction of the battery voltage are avoided. The structure that the temperature sensing unit module is fixedly sealed in the solid-sealed polar pole in a modularization manner is safe and reliable, does not occupy installation space, does not damage the structure of the primary structure, and is convenient to self maintain, so that the on-line monitoring on the temperature of a handcart contact is realized, switch equipment accidents are reduced, the reliability of power supply is improved, and switch equipment state overhaul and intelligent power grid establishment are conveniently realized.
Description
Technical field
The present invention relates to the temperature on-line monitoring device of high voltage electric power equip ment, specifically a kind of structure of high-voltage on-line temperature monitoring wireless transmit pole.
Background technology
The overheated measure of prevention switchgear current loop is one of 18 great anti-accident measures of electrical network of State Grid Corporation of China.Switchgear is the key equipment of electric system, and its running status directly has influence on the power supply reliability of power distribution network.The Medium Voltage Switchgear main product of at present China's production is the middle truck cabinet, accounts for 75%.It is overheated that the handcart contact occurs because the reasons such as loose contact, operational shock, oxidation are normal since contact in contact box, poor radiation, its overtemperature causes the contact box insulation ag(e)ing and causes short circuit accident and occur repeatedly.China proposes the year two thousand twenty and builds up strong intelligent grid comprehensively.Wherein building digital transformer substation and carrying out equipment state overhauling is one of main contents.At first the running status of power equipment must be reflected into supervisory system with digitizing.The power equipment running temperature is to weigh the important parameter of its running status.Adopting pole to make the vacuum switch handcart is switchgear miniaturization, the new technology that improves reliability.It is present domestic switch industry development trend.Temperature sensing unit and the pole of handcart contact temperature on-line monitoring are united two into one.Not only realize safely and reliably handcart contact temperature on-line monitoring, and convenient self keeping in repair in temperature sensing unit.
Summary of the invention
The objective of the invention is to propose on the basis of existing pole structure a kind of simple and reasonable for structure, safe and reliable, and have the structure of long a kind of high-voltage on-line temperature monitoring wireless transmit pole of life-span.
The technical solution adopted for the present invention to solve the technical problems is: a kind of structure of high-voltage on-line temperature monitoring wireless transmit pole, it is characterized in that: an embedded pole main body is arranged, the inner embedding of upper wire outlet seat on the main body has upper induction power supply coil, the main body upper end is provided with wireless transmitter module, and upper induction power supply coil is connected with upper wireless transmitter module by inner lead; Be connected with thermal detector on the upper wireless transmitter module, moving contact touches the sensing temperature signal on upper thermal detector and the outside handcart; Inner embedding of the lower wire outlet seat of main body lower induction power supply coil is arranged, the main body stage casing is provided with lower wireless transmitter module, lower induction power supply coil is connected with lower wireless transmitter module by inner lead, be connected with lower thermal detector on the lower wireless transmitter module, lower thermal detector and outside handcart lower moving contact touch the sensing temperature signal.
The invention has the beneficial effects as follows: two combine into one with the temperature sensing unit of handcart contact temperature on-line monitoring and pole in the present invention, the direct contact-making switch equipment of thermal detector handcart moving contact, realize the measuring point accurately, to measure temperature accurate.Adopt induction power supply coil self-energizing, avoid having a power failure replacing battery and cell voltage reduce impact and measure temperature.The sensing unit modularization is enclosed in the structure of pole admittedly, and reliable isolated high voltage realizes that high voltage is connected without wire with the low voltage signal end.Safe and reliable, do not account in addition installing space, do not destroy the original equipment structure, realize handcart contact temperature on-line monitoring.Be convenient to self maintenance.Reach the switchgear accident that prevents, improve power supply reliability, reduce loss of outage, realize switchgear repair based on condition of component and the purpose of building intelligent grid, have good social effect.
