The invention has the following beneficial effects:

1. when the transformer fails, oil flow enters the oil passing cavity from the oil inlet and leaves the oil passing cavity from the oil outlet, in the process, the baffle plate rotates under the action of the oil flow to enable the plate magnet to move from a normal position to a failure position, the plate magnet is located at the failure position to enable the first transition magnet to have magnetism, the first reed pipe acts under the influence of the magnetic force of the first transition magnet, the flow passing cavity and the electric cavity are two mutually independent cavities, and the first reed pipe arranged in the electric cavity cannot be in contact with the oil at any time, so that the conditions that insulation of a first reed pipe pin is reduced due to the fact that the first reed pipe pin is soaked in the oil, a carbon bridge and the first reed pipe are broken in the prior art are avoided, and the sensitivity and the service life of the first reed pipe are guaranteed; when the first reed switch is required to be overhauled and maintained, oil flow does not flow through the electric cavity, so that the oil path of the transformer does not need to be cut off, only the electric cavity needs to be opened, the maintenance is convenient, and the damage to the overall sealing performance of the transformer is avoided; electric chamber is located oil passing cavity below, under bad weather such as rain, can avoid electric chamber to take place to intake and lead to the condition that electrical component damaged, thereby prolong the life of oil flow velocity of flow relay, but electric chamber sets up in oil passing cavity below, make the distance grow between first tongue tube and the board magnet, it has become weak when this magnetic force that probably leads to board magnet reachs first tongue tube, thereby lead to the unable normal action of first tongue tube, consequently set up first transition magnet in the baffle, board magnet is located fault position back, first transition magnet is magnetized and has magnetism by board magnet, this magnetism guarantees that first tongue tube can in time move, thereby guarantee the normal use of oil flow velocity of flow relay.

2. Produce gas during transformer trouble, when the gas quantity is less, rise to the gas storage intracavity by crossing the oil chamber, thereby make the liquid level decline of gas storage intracavity oil, the liquid level of first response mechanism detectable gas storage intracavity oil, and signals when corresponding liquid level, first response mechanism can be a plurality of hall level sensor that vertical interval set up in the gas storage chamber outside, also can be a plurality of second tongue tubes that vertical interval set up in the gas storage chamber outside and set up the liquid level magnet in the gas storage intracavity, be about to all electrical components and all set up in the gas storage chamber outside, thereby make electrical component can not contact with oil in the course of the work.

3. At least two of the oil passing cavity are not provided with the first through holes which can be closed on different surfaces of the oil inlet and the oil outlet, during installation, according to specific installation environment, the oil passing cavity is installed at first, then the first through holes which are located on the upper end surface of the oil passing cavity are selected, the first through holes and the second through holes at the bottom of the gas storage cavity are communicated through the communicating pipe, so that the gas storage cavity is located above the oil passing cavity, the gas relay can normally work, the gas relay is suitable for multiple different installation environments due to the fact that the first through holes are formed, operation is more convenient, and installation efficiency is also high.

4. When the plate magnet is at the fault position, the plate magnet is adsorbed by the magnetized transition magnet, but because the transition magnet is arranged between the oil passing cavity and the electric cavity and limited by the installation position, the magnetic property of the transition magnet is possibly not large enough, which can lead the plate magnet to recover to the normal position under the condition that the transformer fault is not solved, and after the plate magnet reaches the normal position, the first reed pipe does not send signals any more, and finally more serious consequences can be caused, therefore, the strengthening magnet is arranged in the oil passing cavity, when the plate magnet is at the fault position, the strengthening magnet is also magnetized, the installation space of the strengthening magnet in the oil passing cavity can not be limited, thereby ensuring that the magnetic force of the magnetized plate magnet is enough to adsorb the plate magnet, further avoiding the condition that the plate magnet recovers to the normal position by itself, when the fault is cleared, the plate magnet can be reset, the electromagnet is electrified, and the electromagnet generates a magnetic force larger than the strengthening magnet, adsorb board magnet to normal position by the trouble position, so can make the oily chamber of crossing completely sealed to stop to cross the oily chamber and take place the condition of oil leak.

5. Transition magnet is including upwards extending to the vertical portion of crossing in the oil cavity, and when board magnet was located the trouble position, a side and a terminal surface of keeping away from the oil inlet were adsorbed by the vertical portion after the magnetization respectively with strengthening magnet, can guarantee better that board magnet can not reset to normal position under the condition that transformer trouble was not solved.

6. When the oil flow velocity adjusting device is used, the inclination of the baffle plate can be adjusted through the adjusting mechanism according to the oil flow velocity in actual working conditions, so that the force of pushing the baffle plate is reduced or increased, and the universality of the oil flow velocity relay is improved.

7. The oil passing cavity and the electric cavity are mutually independent and horizontally arranged, the first reed pipe is vertically arranged in the electric cavity, so that the first reed pipe is not in contact with oil except for the fact that the first reed pipe is not in contact with the oil, the baffle plate is thinned, and the plate magnet is arranged close to the first reed pipe, so that the plate magnet can be guaranteed to act on the first reed pipe when in a fault position, and the first reed pipe is directly driven by the plate magnet, so that the structure is simpler.

8. To some occasions of focusing on preventing maloperation, need be under the circumstances that a plurality of first tongue tubes send out the signal in proper order, the oil flow velocity moves the relay and can just carry out the protection action, consequently set up a plurality of first tongue tubes at the vertical interval in electric cavity, board magnet is by the normal position to the in-process of fault location, first tongue tube will move step by step because of receiving the influence of board magnet in proper order, thereby satisfy the requirement of preventing maloperation, set up self-sustaining magnet in the oily intracavity of mistake, when board magnet is located the fault location, adsorb and hold board magnet, thereby make board magnet realize self-sustaining.
