Abstract
The utility model relates to a monitoring device for a heating tape of a tank type breaker. The heating tape is connected with a current isolator in series, the current isolator is connected with a relay in parallel, and the relay is connected with an indicating lamp in series. A high current of an operating loop of the heating tape is effectively isolated by the current isolator, a safe current isolated by the effective isolation of the current isolator is detected by the relay, and the indicating lamp of the operation state is driven to effectively monitor the operating condition of the heating tape. If the heating tape operates normally, the current isolator outputs current normally, the relay monitors the current, the indicating lamp of the operation state of the heating tape is on, and the heating tape is indicated to be operating normally; if the heating tape does not operate or has abnormal conditions, the current isolator does not output the current, the relay returns or does not operate, the indicating lamp of the operation state of the heating tape is off, and the heating tape is indicated not to operate or to operate abnormally.
Description
[technical field]
The utility model relates to the high voltage switchgear in a kind of high-voltage electric power system, particularly a kind of potting breaker heating tape monitoring device.
[background technology]
Referring to shown in Fig. 1, is current heating tape operating circuit structure chart, and when ambient temperature is during lower than-25 ℃, thermostat KT1 starts, KT1 closing of contact starting contactor KTX1, and the KTX1 closing of contact starts heating tape SH41; When ambient temperature is during lower than-30 ℃, thermostat KT2 starts, KT2 closing of contact starting contactor KTX2, and the KTX2 closing of contact starts heating tape SH42.
At present for SF
6there is the phenomenon of gas liquefaction in circuit breaker, for guaranteeing normal operation of circuit breaker, often adopt and on case for circuit breaker, install attemperator additional when extremely frigid zones is used.When ambient temperature is lower than SF
6during gas liquefaction temperature, by thermostat control heater input or out of service automatically, to SF in circuit breaker
6gas heats, and guarantees the performance of circuit breaker.
If there is no heating tape monitoring device, whether user cannot understand heating tape and normally work, and heating tape damages in the time of cannot normally dropping into, and will affect the normal operation of product.
[utility model content]
The purpose of this utility model is to provide a kind of potting breaker heating tape monitoring device, reflects truly, timely the running status of heating tape, is the reliable service data that provides of safeguarding and moving.
In order to address the above problem, the utility model adopts following technical scheme:
A kind of potting breaker heating tape monitoring device, heating tape is in series with the galvanic separation that detects heating tape work loop current, described galvanic separation is parallel with relay, described relay is in series with indicator light, and described relay gathers the electric current rear drive indicator light of galvanic separation heating tape is monitored.
As preferred embodiment of the present utility model, described relay pack vinculum circle and contact switch, wherein, described coil is in parallel with galvanic separation, and described contact switch is connected with indicator light.
As preferred embodiment of the present utility model, described galvanic separation at least comprises the coil that is wrapped in conduction periphery, by coil-induced electric current.
With respect to prior art, the utlity model has following advantage: the utility model is series current isolator on heating tape, galvanic separation relay in parallel, and relay indicating lights connected in series, like this, after safe current after high electric current on heating tape work loop is effectively isolated by galvanic separation is arrived by relay test, drive working station indicator effectively to monitor with the working condition to heating tape.When heating tape is normally worked, the normal output current of galvanic separation, relay monitors after electric current, and heating tape working station indicator is bright, and heating tape normal operation is described; When heating tape is not worked or abnormal conditions occur, galvanic separation does not have electric current output, and relay returns or is failure to actuate, and heating tape working station indicator goes out, and illustrates that heating tape is not worked or operation irregularity.
[accompanying drawing explanation]
Fig. 1 is the operating circuit structure chart of traditional heating tape;
Fig. 2 is the circuit theory diagrams of the utility model monitoring device;
Fig. 3 is the particular circuit configurations figure of the utility model monitoring device.

Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to shown in Fig. 2, a kind of potting breaker heating tape monitoring device, heating tape is in series with the galvanic separation that detects heating tape work loop current, described galvanic separation is parallel with relay, described relay is in series with indicator light, and described relay gathers the electric current rear drive indicator light of galvanic separation heating tape is monitored.Described relay pack vinculum circle and contact switch, wherein, described coil is in parallel with galvanic separation, and described contact switch is connected with indicator light.
Refer to shown in Fig. 3, when heating tape SH41 or SH42 normally work, galvanic separation LBH senses electric current, and relay LTD contact starts, and indicator light is bright.
The utility model heating tape monitoring system, by sealing in the galvanic separation in heating tape work loop, is carried out current acquisition and the high electric current in its loop is effectively isolated; The safe current that relay gathers after galvanic separation isolation drives working station indicator effectively to monitor the working condition of heating tape, galvanic separation is sealed in heating tape work loop, and by relay, galvanic separation electric current is monitored, when heating tape is normally worked, the normal output current of galvanic separation, the actuating of relay, heating tape working station indicator is bright, and heating tape normal operation is described; When heating tape is not worked or abnormal conditions occur, galvanic separation does not have electric current output, and relay returns or is failure to actuate, and heating tape working station indicator goes out, and illustrates that heating tape is not worked or operation irregularity.
The utility model heating tape monitoring device feature:
(1) safe and reliable, guarantee operating personnel's personal safety;
(2) antijamming capability is strong, and system works is reliable;
(3) system is exported a dynamic circuit connector one dynamic circuit breaker node, is user-friendly to, and from master-control room, monitors;
(4) mounting means is simple, only need, by the line of heater through galvanic separation, provide power supply to indicator light simultaneously.
The utility model heating tape monitoring device implementation result:
