Technical Field
The invention relates to the technical field of power facility maintenance, in particular to an automatic drainage device for an emergency oil pool of a transformer.
Background
All be provided with the dedicated accident oil bath of transformer at present, this accident oil bath primary function is in order to collect transformer exhaust waste oil when breaking down, but because it is outdoor setting, can appear collecting the condition of rainwater, does not take place to overflow in order to guarantee transformer exhaust accident waste oil, need regularly clear up the rainwater of collecting in the accident oil bath, so electronic drainage system is often installed in this accident oil bath.
In addition, the current transformer substation adopts a mode of manually and periodically starting the drainage pump to drain water, and has the following defects that firstly, manual starting is needed, and manpower is wasted; secondly, the amount of collected water in each period is small, even if no water is collected in the drought period, manual inspection and confirmation are needed; and thirdly, if the drainage is in place, manual confirmation or continuous monitoring is required, so that the manpower is wasted, and if the drainage is not carried out in time, the water pump is closed, so that the motor is easy to idle and damage.
Disclosure of Invention
Aiming at the defects and shortcomings in the prior art, the invention provides an automatic drainage device for an accident oil pool of a transformer, which can be automatically started at regular time without manual starting; secondly, the water level monitoring sensor can sense the current water amount, if the water amount is collected more, the drainage is started immediately, and if the water amount is collected less in a period of time, the starting frequency of the water pump can be reduced, the motor is protected, and the service life of the equipment is prolonged; and thirdly, the water discharge stopping water level can be set, so that the water pump motor can be automatically stopped when the water pump reaches the water discharge stopping water level without being monitored by personnel on site all the time.
The invention specifically adopts the following technical scheme:
the utility model provides a be used for automatic drainage device of transformer accident oil bath which characterized in that: a low water level sensor is arranged above the bottom of the transformer accident oil pool, and a high water level sensor is arranged below a water outlet of the water pump; the low water level sensor and the high water level sensor are electrically connected to the automatic water pump controller; and the automatic water pump controller is connected to a drainage pump arranged in the transformer accident oil pool through a switch of the control power supply.
Further, the switch comprises a gear for switching to manual control and a gear for switching to the automatic controller of the water pump.
Further, the automatic water pump controller is provided with a time relay.
Furthermore, the automatic water pump controller is set to be automatically started at regular time, senses the current water quantity through the water level monitoring sensor, immediately starts drainage if the water quantity is collected more, and reduces the starting frequency of the water pump if the water quantity is collected less in a period of time so as to protect the motor and prolong the service life of equipment.
Further, the automatic controller of the water pump is provided with a drainage stop water level, and when the drainage stop water level is reached, the motor of the water pump is automatically stopped.
Compared with the prior art, the invention and the preferred scheme thereof have the first that the invention can be automatically started at regular time without manual starting; secondly, the current water quantity can be sensed through a water level monitoring sensor, if the water quantity is collected more, the drainage is started immediately, and if the water quantity is collected less in a period of time, the starting frequency of the water pump can be reduced, a motor is protected, and the service life of equipment is prolonged; and thirdly, the water discharge stopping water level can be set, so that the water pump motor can be automatically stopped when the water pump reaches the water discharge stopping water level without being monitored by personnel on site all the time.
