Specific embodiment
In order to make the invention's purpose, features and advantages of the invention more obvious and easy to understand, below in conjunction with the present invention
Attached drawing in embodiment, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that disclosed below
Embodiment be only a part of the embodiment of the present invention, and not all embodiment.Based on the embodiments of the present invention, this field
Those of ordinary skill's all other embodiment obtained without making creative work, belongs to protection of the present invention
Range.
In the description of the present invention, it is to be understood that, term " on ", "lower", "top", "bottom", "inner", "outside" etc. indicate
Orientation or positional relationship be based on the orientation or positional relationship shown in the drawings, be merely for convenience of description the present invention and simplification retouch
It states, rather than the device or element of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation,
Therefore it is not considered as limiting the invention.It should be noted that when a component is considered as " connection " another component,
It can be directly to another component or may be simultaneously present the component being centrally located.
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, the present invention provides it is a kind of can instantaneous pressure release 10kV high-voltage explosion-proof metering cabinet, including metering cabinet body
And the interlayer 1 of metering interior of the cabinet is set, the interlayer 1 will measure cabinet body and be divided into measuring instrument installation room 2 and mutual inductance
Device installs room 3, and the inside of measuring instrument installation room 2 is equipped with main electric energy meter 4, secondary electric energy meter 5, master terminal 6 and pair eventually
End 7 is also configured on measuring instrument installation room 2 and is spaced apart 14 and mutual inductor is secondary the terminal box of terminal occurs for connecting
15, the bottom of mutual inductor installation room 3 be equipped with can instantaneous pressure release high-pressure decompression valve 8, the metering cabinet body up and down also
Be separately installed with and room 2 and the mutual inductor installation upper cabinet door 9 that matches of room 3 and lower cabinet door 10 be installed with measuring instrument, it is described on
Visual window 11 is installed in cabinet door 9.
The present invention is additionally arranged at the bottom high-pressure decompression valve 8 mutual inductor installation room 3, can at the first time will explosion time occurs
High temperature and high pressure gas abrupt release prevents cabinet door from flying out and hurts sb.'s feelings, while preventing its explosion from causing other equipment impaired or causing to connect
Ring explosion；The double terminals of double tables are installed additional in instrument installation room 2 of the invention, meet the needs of existing trade user, while visual window
11 design can see inner case clearly when not opening upper cabinet door 9.
Specifically, as shown in Fig. 2, the high-pressure decompression valve 8 includes the pressure release for being mounted on the mutual inductor installation 3 bottom of room
The upper end of slot 801, the gas pressure relief slot 801 offers air guide port and lower end offers pressure relief opening, and the pressure relief opening is through described mutual
The bottom of sensor installation room 3 is simultaneously connected to outside, is equipped in the pressure relief opening for the rupture pressure disc in explosion time rupture pressure release
802。
Above-mentioned air guide port has the function of that one guides to the gas that generates in mutual inductor installation room 3, when exploding
When, high temperature and high pressure gas is entered in gas pressure relief slot 801 by air guide port, and rupture pressure disc 802 here is in the prior art mounted in pressure
Upper vessel portion prevents the metallic film of container explosion, is a kind of safety device, also known as explosion rupture disk or rupture disk.When container internal pressure
When power is more than certain limit, film is first broken through, thus can reduce the pressure in container, avoids exploding.Pass through the anti-of bottom
Quick-fried film 802 guides high-temperature high-pressure air flow, and metering cabinet body the explosion of its first time of explosion time occurs and releases pressure, prevents cabinet door bullet
Out.
As present invention further optimization, in order to accelerate the rupture of rupture pressure disc 802, guarantee that high temperature and high pressure gas can be
It is released at the first time, the upper end of the gas pressure relief slot 801 is provided with upper cover plate 803, and the upper cover plate 803 passes through compressed spring
804 connect with the bottom of the gas pressure relief slot 801, and the air guide port is mounted on upper cover plate 803, and the edge of the air guide port to
Under extend to form a round tube 805, the end of the round tube 805 is provided with the sharp portion 806 that can poke rupture pressure disc 802.
When high temperature and high pressure gas release, one side gas directly collides rupture pressure disc 802 and promotes its rupture, in another aspect
Under pressure, deformation occurs for compressed spring 804 for cover board 803, drive upper cover plate 803 move down, thus round tube 805 also to
Rupture pressure disc 802 is directly poked in the sharp portion 806 of lower movement, 805 lower part of round tube, and the rupture in emergency circumstances explosion-proof 802 is played
The effect of dual guarantee.
In addition, the gas of high temperature and pressure also functions to contention effect to interlayer 1 when explosion time occurs in mutual inductor installation room 3,
Interlayer connection do not fasten may cause high temperature and high pressure gas collides upwards enter measuring instrument installation interior force cabinet door pop-up
It hurts sb.'s feelings.
Therefore, as shown in figure 3, the interlayer 1 of the invention includes the net-like spacer for being fixedly mounted on metering interior of the cabinet
101, it is provided with expanded rubber piece 102 on the net-like spacer 101, the edge of the expanded rubber piece 102 and metering cabinet body
Inner wall is fixedly connected, and the fold of several stackings is provided on the expanded rubber piece 102, is equipped at the fold of the stacking
Several concentric annulus 103.
Here 101 one side of net-like spacer plays the role of measuring cabinet body isolation up and down, on the other hand to expanded rubber
Piece 102 plays a supporting role, and when gas release occurs for explosion, expanded rubber piece 102 has certain elasticity, with one heart
Annulus 103, which moves upwards, makes the fold stacked be unfolded into one and arch upward, and a dilatation is played to mutual inductor installation room 3 by the place of arching upward
Effect, buffer a part of pressure.
Further, in order to guarantee the installation stability of upper cabinet door 9 and lower cabinet door 10, one end of the upper cabinet door 9 and institute
It is hinged to state measuring instrument installation room 2, the other end of the upper cabinet door 9 passes through lead sealing screw 12 and measuring instrument is installed room 2 and consolidated
Fixed connection；The both ends of the lower cabinet door 10 pass through bolt 13 and are fixedly connected with mutual inductor installation room 3, and between the bolt 13
It is reinforced with lead sealing screw 12, the upper cabinet door 9 and the edge of lower cabinet door 10 are provided with the edge sealing 16 for deadend.
The above, the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although referring to before
Stating embodiment, invention is explained in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features；And these
It modifies or replaces, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
