Abstract
The invention relates to a transformer oil pond water drainage device aiming at overcoming the defects of the prior art. A water level detection electrode A and an electrode B with a water level detection circuit are electrically connected to an executing mechanism electric water pump D which is connected with a 220v alternating-current power supply through a blocking signal circuit and a time-base switching circuit. The transformer oil pond water drainage device is characterized in that the time-base switching circuit consists of a time-base integrated circuit IC which is electrically connected to a relay J through a transistor G; the electric water pump D, the water level detection electrode A and the electrode B are arranged in a lower groove which is arranged at the bottom of a transformer emergency oil pond; and the blocking signal circuit consists of a float magnetically-controlled switch. The transformer oil pond water drainage device has the advantages that since the electrodes with the water level detection circuit are adopted, the misoperation of the automatic water drainage device caused by a reason that the water detection electrode A and the electrode B become damp can be avoided and dual-failsafe control of a transformer is realized; and since the lower groove is arranged at the bottom of the transformer emergency oil pond, the goal of automatically draining water to guarantee the oil storage capacity of the transformer emergency oil pond is realized.
Description
Technical field
The present invention relates to power transformer guard technology field, relate in particular to a kind of transformer oil sump dewatering installation.
Background technology
At present, China's power transformer is arranged on open air mostly, because the water of heavy rain, severe snow can enter the transformer oil sump from the transformer pond, generally enters the water of transformer oil sump, is all to check draining by manual patrol at present.And present transformer station all realizes unattended, when the weather of heavy rain, severe snow occurs, the water inlet of transformer oil sump fails to discharge in time, occupies the capacity of transformer oil sump due to the oil sump off-capacity, under accident condition, transformer oil very easily catches fire, and burns the fire incident of transformer.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of transformer oil sump dewatering installation, can realize transformer oil sump Auto-drainage, avoid the accident of Causing Fire in Transformer.
In order to realize the foregoing invention purpose, the present invention adopts following technical scheme:
A kind of transformer oil sump dewatering installation, the detecting water level detecting electrode A with water level detection circuit and electrode B by the block signal circuit, the time base on-off circuit be electrically connected to the executing agency electric water pump D connected with exchanging the 220v power supply.
A kind of transformer oil sump dewatering installation, when described, the base on-off circuit is electrically connected to relay J by time-base integrated circuit IC by transistor G and forms.
A kind of transformer oil sump dewatering installation, described electric water pump D
,water level detecting electrode A and electrode B are positioned at the Transformer Emergency Oil Pond low groove that the Transformer Emergency Oil Pond bottom arranges
.
A kind of transformer oil sump dewatering installation, described block signal circuit is comprised of the floating ball magnetic control switch,
Owing to adopting as above technical scheme, the present invention has following superiority:
A kind of transformer oil sump dewatering installation, adopt the electrode detector water level detection circuit, can prevent the self-draining arrangement misoperation that detecting water level detecting electrode A and electrode B are made moist and caused, realizes transformer dual fail-safe control.Owing in the Transformer Emergency Oil Pond bottom, being provided with low groove, realize guaranteeing the Transformer Emergency Oil Pond oil tankage by Auto-drainage.
figure of description
Fig. 1 is the circuit block diagram of transformer oil sump dewatering installation;
The specific embodiment
As shown in Figure 1: a kind of transformer oil sump dewatering installation, the detecting water level detecting electrode A with water level detection circuit and electrode B by the block signal circuit, the time base on-off circuit be electrically connected to the executing agency electric water pump connected with exchanging the 220v power supply.
This transformer oil sump dewatering installation, when described, the base on-off circuit is electrically connected to relay J by time-base integrated circuit IC by transistor G and forms.
This transformer oil sump dewatering installation, described electric water pump D
,water level detecting electrode A and electrode B are positioned at the Transformer Emergency Oil Pond low groove that the Transformer Emergency Oil Pond bottom arranges
.
This transformer oil sump dewatering installation, described block signal circuit is comprised of floating ball magnetic control FQ switch,
During use, when the weather of heavy rain, severe snow occurs when, water inlet in the transformer oil sump, when in emergency oil pond, water level reaches to high water level electrode A place, ball float moves up, floating ball magnetic control switch FK conducting, the triggering pin of time-base integrated circuit IC is high level, the trigger upset of time-base integrated circuit IC inside, from the output pin output low level, make to control transistor G conducting, the relay J adhesive, its constant open contact is connected, electric water pump running work, and accident transformer oil sump starts outside draining.When transformer oil pool inner water position drops to low water level electrode B place, oil sump bottom, ball float moves down, floating ball magnetic control switch FQ disconnects, the triggering pin voltage of time-base integrated circuit IC becomes low level simultaneously, and the trigger upset, from output pin output high level, make transistor G cut-off, relay J is in release conditions, and its contact disconnects, and water pump stops draining.
