Abstract
The utility model provides a pressure release channel of a middle-voltage switchgear, which comprises a switchgear. The cabinet top of the switchgear is equipped with a pressure release device, and the pressure release channel connected with the pressure release device is arranged over the pressure release device, wherein one end of the pressure release channel is sealed, and the other end of the pressure release channel is connected with the outdoor via a wall. The pressure release channel of the middle-voltage switchgear provided by the utility model overcomes disadvantages in the prior art, can ensure normal arcing pressure release while releasing high-temperature high-pressure gas to the outdoor, does not influence normal operation of adjacent switchgears, provides convenience for timely maintenance of the switchgear, and ensures safety of environment and operation staff of a distribution room.
Description
Technical field
The utility model relates to a kind of pressure release passage of medium voltage switchgear equipment, is used for medium voltage switchgear equipment owing to after the short circuit accident generation arcing, make things convenient for switching devices to safeguard timely and overhaul, and belongs to power transmission and distribution switchgear technical field.
Background technology
In power transmission and transformation system, switchgear is wherein important part, is realizing the conveying and the distribution of electric energy in electric power system.Because general life-span of switchgear about 20 years, is an important link for the maintenance and the maintenance of switchgear.For 3kV～40.5kV ac metal closing switch gear, in order to prevent that short circuit accident from causing the damage to personnel and other equipment, require switchgear to possess arcing pressure release function, domestic common employing is at switch cabinet top design pressure relief device, after switchgear is short-circuited the accident arcing, high pressure-temperature gas releases from the cabinet top, prevents from peripheral operating personnel and other equipment are produced damage.
And for the European medium voltage switchgear equipment of outlet, the client has higher specification requirement to it, because of though domestic pressure release design does not produce damage to peripheral operating personnel and other equipment, but high temperature and high pressure gas is let out to power distribution room after the pressure release, cause power distribution room dense smoke to fill the air, and contain pungent even poisonous gas, fill the air and to safeguard in time and to overhaul owing to dense smoke because of the back that has an accident simultaneously, cause secondary economic loss, so European customer requirement medium voltage switchgear equipment increases a pressure release passage when possessing pressure relief device, high pressure-temperature gas is drained into the open air.
The utility model content
The technical problems to be solved in the utility model provides a kind of pressure release passage of medium voltage switchgear equipment, with at medium voltage switchgear equipment owing to after the short circuit accident generation arcing, make things convenient for switching devices to safeguard in time and overhaul, for putting into operation sooner of stand-by equipment provides safeguard.
In order to solve the problems of the technologies described above, the technical solution of the utility model provides a kind of pressure release passage of medium voltage switchgear equipment, comprise switchgear, the cabinet top of switchgear is provided with pressure relief device, it is characterized in that: described pressure relief device top is provided with the pressure release passage that is connected with described pressure relief device, the sealing of pressure release passage one end, the pressure release passage other end connects outdoor by body of wall.
Preferably, described pressure relief device comprises breaker chamber pressure release lid, first bus-bar room pressure release lid, the second bus-bar room pressure release lid and the cable vault's pressure release lid that is arranged in order layout, and the pressure release passage of breaker chamber pressure release lid, first bus-bar room pressure release lid, the second bus-bar room pressure release lid and cable vault's pressure release side of covering connects as a whole.
The exhaust passage of the pressure release passage of a kind of medium voltage switchgear equipment that the utility model provides for increasing in the former switchgear cabinet top pressure relief device outside, after producing short circuit accident in the cabinet, pressure relief device is opened automatically, high temperature and high pressure gas is discharged cabinet to pressure release passage, by the gas outlet high temperature and high pressure gas is all passed body of wall again and drain into the open air, do not influence the normal operation of adjacent switch equipment simultaneously.
The pressure release passage of a kind of medium voltage switchgear equipment that the utility model provides has following beneficial effect:
(1) pressure release passage satisfies degree of protection IP4X, arcing grade 31.5kA/0.5s;
(2) for overhauling quickly after having an accident and maintenance provides safeguard;
(3) ensure the environment of power distribution room and operating personnel's safety better;
(4) the more normal operation of other switchgear of reliable guarantee
The pressure release passage of a kind of medium voltage switchgear equipment that the utility model provides has overcome the deficiencies in the prior art, can be when guaranteeing normal arcing pressure release, high temperature and high pressure gas is drained into the open air, do not influence simultaneously the normal operation of adjacent switch equipment, make things convenient for switching devices to safeguard in time and overhaul, ensured the environment of power distribution room and operating personnel's safety.

Embodiment
For the utility model is become apparent, now with a preferred embodiment, and conjunction with figs. is described in detail below.
The pressure release passage schematic diagram of a kind of medium voltage switchgear equipment that Fig. 1 provides for the utility model, the pressure release passage of described a kind of medium voltage switchgear equipment comprises switchgear 1, switchgear 1 is the exemplary apparatus of Medium Voltage Switchgear, increase an exhaust passage in the pressure relief device outside, former switchgear 1 cabinet top, it is pressure release passage 2, after various schemes were pieced together cabinet in power distribution room, pressure release passage interconnected, and by the gas outlet high temperature and high pressure gas is all passed body of wall 7 and drains into the open air.
The pressure relief device of switchgear 1 comprises breaker chamber pressure release lid 3, first bus-bar room pressure release lid 4, second bus-bar room pressure release lid 5 and the cable vault's pressure release lid 6 that is arranged in order layout, pressure relief device is opened automatically after producing short circuit accident in the cabinet, high temperature and high pressure gas is discharged cabinet to pressure release passage 2, do not influence the normal operation of adjacent switch equipment simultaneously.
This pressure release passage has guaranteed the operation of power distribution room safety and reliability when satisfying degree of protection IP4X, arcing grade 31.5kA/0.5s, ensure the environment of power distribution room and operating personnel's safety, overhauls more timely and maintenance provides powerful guarantee for faster.
