Abstract
The utility model discloses an automatic locking device for a switch house door in SF6 gas leakage, which comprises an SF6 gas leakage detection device. The SF6 gas leakage detection device is connected with a collector, and an alarm starting loop point of the SF6 gas leakage detection device is connected with an alarm device and a fan controller. The fan controller is connected with a fan. The alarm starting loop point of the SF6 gas leakage detection device is connected with an electromagnetic lock. When in leakage of SF6 gas, the automatic locking device can send alarm and can lock a switch house of SF6 equipment so as to prevent operators from approaching.
Description
Technical field
The utility model relates to the device that a kind of switchgear house door detects the SF6 gas leakage, is specifically related to a kind of device that can in time when gas leakage, the switchgear house door be closed.
Background technology
In recent years, along with China's power industry develops the raising with technical equipment rapidly.The SF6 electric equipment puts into operation in a large number, if equipment leakage, because the SF6 molecular weight gas is bigger than air molecule amount, so SF6 gas is sunken to the below of air, causes accumulating SF6 gas in a large number and causing the generation of anoxia asphyxia accident in the equipment lower space.The switchgear house that present each transformer station is equipped with the SF6 electric equipment all is defined in the staff porch, power distribution equipment chamber that SF6 equipment is housed according to " State Grid Corporation of China's electric power safety working regulation (power transformation part) " 8.1,8.5 outdoors and is equiped with the SF6 gas leak detection apparatus; Can realize SF6 gas content and oxygen content in the testing environment air; The SF6 gas content exceeds standard or anoxic in environment; Can report to the police in real time; Automatically open ventilation blower simultaneously and ventilate, and have many functions of enriching such as humiture detection, operating state voice suggestion, teletransmission warning, the inquiry of historical data, but it is related not have mutual locking between this device and the power distribution equipment chamber door; The staff still can arbitrarily pass in and out the power distribution equipment chamber that SF6 equipment is housed when reporting to the police, and can not effectively guarantee staff's safety.
The utility model content
The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of switchgear house door SF6 gas leakage self-locking gear is provided, and when SF6 leaked, this device was reported to the police simultaneously that the power distribution equipment chamber of SF6 equipment is locked, prevents that the staff from coming in and going out.
The technical scheme of the utility model realizes in the following manner: a kind of switchgear house door SF6 gas leakage self-locking gear; Comprise the SF6 gas leak detection apparatus; The SF6 gas leak detection apparatus links to each other with collector; The SF6 gas leak detection apparatus warning start the loop point and link to each other with controller of fan with warning device, controller of fan links to each other with blower fan, the SF6 gas leak detection apparatus warning startup loop point link to each other with electromagnetic lock.
Said warning device is an acoustic-optic alarm.
The utility model seals in electromagnetic lock with the warning startup loop point of SF6 gas leakage monitoring device; When monitoring in the SF6 gas leakage monitoring and alarming system that SF6 gas exceeds standard or oxygen content when lowering, connect by internal node and report to the police and the fan starting loop, connect the electric power loop of electromagnetic lock simultaneously; Locking switchgear house gate; Avoid personnel arbitrarily to get into, when confirmation signal wrong report or staff had taked safety prevention measure to get into, available unlock key was opened this lockset and is got into switchgear house.And the monitoring and alarming system of SF6 gas leakage does not at ordinary times start and reports to the police and during the fan starting loop, the electromagnetic lock electric power loop is disconnected, and electromagnetic lock is inoperative, by original lockset Lock effect on the door, does not influence normal use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; A kind of switchgear house door SF6 gas leakage self-locking gear; Comprise SF6 gas leak detection apparatus 1, SF6 gas leak detection apparatus 1 links to each other with collector 2, SF6 gas leak detection apparatus 1 warning start loop point and link to each other with controller of fan 4 with warning device 6; Controller of fan 4 links to each other with blower fan 7, SF6 gas leak detection apparatus 1 warning start loop point and link to each other with electromagnetic lock 3.
Said warning device 6 is acoustic-optic alarms.
When the utility model used, electromagnetic lock was contained on the switchgear houses, and the utility model utilizes electromagnetic lock to utilize the principle of electric magnetisation, and when electric current passed through silicon steel sheet, electromagnetic lock can produce the strong suction absorption iron plate that holds tightly and reach the effect of locking a door.On the door of switchgear house, install an electromagnetic lock additional, SF6 gas leakage device monitoring is exceeded standard or both associations are just realized in the oxygen content startup loop of lower reporting to the police as the power supply of electromagnetic lock to SF6 gas.
Claims (2)
1. switchgear house door SF6 gas leakage self-locking gear; Comprise SF6 gas leak detection apparatus (1); SF6 gas leak detection apparatus (1) links to each other with collector (2); SF6 gas leak detection apparatus (1) warning start loop point and link to each other with controller of fan (4) with warning device (6), controller of fan (4) links to each other with blower fan (7), it is characterized in that: SF6 gas leak detection apparatus (1) warning startup loop point link to each other with electromagnetic lock (3).
