Description
Technical Field
The utility model relates to a gas relay warning field, more exactly is gas relay volume pre-alarm device.
Background
The gas relay is a protection device for oil immersed transformer, reactor and on-load tap-changer with oil conservator. The device is arranged in a connecting pipeline between a transformer and an oil conservator, when the transformer and a reactor (or an on-load tap changer) have faults in operation, the transformer oil is decomposed to form gas, when the gas reaches a certain volume, an upper floater sinks, a magnet is arranged on the upper floater, and a volume contact (reed pipe) is closed under the action of the attraction force of the magnet to transmit an alarm signal.
The internal structure of the gas relay on the market at present is that gas volume contacts are all synchronous output, can't accomplish the multinomial output of gas volume parameter, and volume contacts do not move when the transformer produces the inside trace gas that produces of gas relay after breaking down, and no signal spreads, and the trouble that the transformer produced just can not be found by real time. The volume contact (reed pipe) is closed to send out an alarm signal only when the upper float sinks to a preset position when the gas reaches a certain volume.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a gas relay volume is alarm device in advance for can not discover and overhaul the very first time after solving among the prior art when the transformer produces the trouble, the problem that a small amount of transformer fault can not be answered in the time of gaseous.
In order to solve the above problem, the technical scheme of the utility model is that: the volume pre-alarming device of the gas relay is provided with a device which can output gas volume contacts step by step and realize the early-warning function.
A volume pre-alarming device of a gas relay comprises a shell 1, a support 2, an upper float 3, a volume pre-alarming reed switch contact 4, a volume alarming reed switch contact 5, an upper float magnet frame 6, an upper float magnet frame magnet 7, an upper float swing arm 8, an upper float shaft 9 and a reed switch support 10, wherein the lower end of the upper shell 1 is fixedly connected with the upper end of the support 2 through bolts, the side surface of the support 2 is provided with the upper float shaft 9 which is fastened through nuts, the upper float swing arm 8 is fixed on the upper float shaft 9, the upper float 3 is fixed on the upper float swing arm 8, the lower end of the upper float 3 is arranged below the support 2, the left side and the right side of the support 2 are respectively fixedly connected with the reed switch support 10 through bolts, and the left volume pre-alarming reed switch contact 4 and the right volume alarming reed switch contact 5 are arranged in the reed switch support 10. An upper float magnet frame 6 is fixed on the outer side of an upper float swing arm 8, a magnet 7 is arranged in the upper float magnet frame 6, and the magnet 7 is matched with a left volume pre-alarm reed pipe contact 4 and a right volume alarm reed pipe contact 5.
When gas appears in the gas relay, the upper float swing arm 8, the upper float magnet frame 6, the magnet 7 in the upper float magnet frame rotate and descend along with the float shaft 9 above the upper float 3 as a center to a certain limit position, and when the magnet 7 is close to the matched volume pre-alarm reed pipe contact 4, the volume reed pipe contact 4 is closed to send out a pre-alarm signal. Along with the gathering of gas in the relay, the upper float swing arm 8, the upper float magnet frame 6, the magnet 7 in the upper float magnet frame continue to rotate and descend along with the floater shaft 9 above the upper float 3 as a center, and when the magnet 7 approaches the matched volume reed pipe contact 5, the volume reed pipe contact 5 is closed to send out an alarm signal.
The utility model has the advantages of:
volume pre-warning device: the volume pre-alarming switch is arranged, when 100-200 ml of transformer fault gas occurs in the gas relay, a pre-alarming signal is sent out, and when the gas volume is increased to 250-300ml again, an alarming signal is sent out, so that the transformer fault maintenance is more timely. The left side volume pre-alarm reed switch contact realizes that the function is reported to the police when a small amount of gas 100~200ml appears in gas relay inside, and the main benefit is that inform control system or monitoring system, confirm that a small amount of gas has appeared in gas relay inside and play the warning effect. When the gas relay is provided with the pre-alarm function, whether the gas volume alarm is a false operation alarm or not can be identified, the standard volume action value of the gas relay is 250-300ml, for example, the volume pre-alarm does not transmit a signal, the volume alarm directly transmits a signal, and the volume alarm can be judged to be the false operation.
