Abstract
The invention provides a transmitter detection device which comprises a pressure reducing device, a pressure detection device, a flow control device, a flow measuring device and a gas storage device. Gas with known components is stored in the gas storage device and enters a transmitter to be detected through the transmitter detection device; due to the fact that the transmitter detection device can control (regulate) the gas pressure and gas flow in the gas discharging process and the gas with the known components is stored in the gas storage device, whether transmitter monitoring gas component values in a gas leakage monitoring and alarming device are accurate and whether the reaction speed and the detection sensitivity are qualified can be verified, and it is guaranteed that the gas leakage monitoring and alarming device can accurately monitor the gas leakage of an indoor substation.
Description
Technical field
The present invention relates to instrument, instrument and industrial automation, be specifically related to a kind of transmitters sense device.
Background technology
In electric power network, be provided with multiple indoor substation, in order to ensure the normal work of power equipment in indoor substation, need being filled with a certain amount of sulfur hexafluoride gas in indoor substation, and require that the concentration of sulfur hexafluoride gas maintains in certain zone of reasonableness.But indoor power station can not reach 100% to be sealed completely, there is the possibility of leaking in its inner sulfur hexafluoride gas, to this, technician often adopts gas leakage alarm to monitor it.Existing gas leakage alarm mainly comprises transmitter and gas leakage alarm main frame, wherein transmitter is can by the converter of the signal of controller identification for the output signal of sensor is changed into, if transmitter accurately cannot carry out signal transformation, monitoring result will inevitably be caused inaccurate, if transducer signal changes, sensitivity is low or signal transformation time delay is high, will inevitably cause cannot monitoring Leakage Gas in time.
Summary of the invention
The present invention is directed to the deficiencies in the prior art part, a kind of transmitters sense device is provided.
The scheme that the present invention solves prior art problem is: a kind of transmitters sense device, comprise reliever, pressure-detecting device, volume control device, flow measurement device and gas storage device, wherein, the gas of known composition is stored in described gas storage device; Described gas storage device, described reliever, described volume control device and described flow measurement device connect successively, and described pressure-detecting device is connected between described reliever and described volume control device.A kind of gas leakage alarm, comprises interconnective gas leakage alarm main frame and described transmitters sense device.
Accompanying drawing explanation
Fig. 1 is the structural representation of transmitters sense device of the present invention first embodiment.
Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention are described in detail.Certainly, below description related to the preferred embodiment be only exemplary, and be never the restriction to the present invention and application or usage.
Transmitters sense device as a kind of in Fig. 1, comprises reliever, pressure-detecting device, volume control device, flow measurement device and gas storage device, wherein, stores the gas of known composition in described gas storage device; Described gas storage device, described reliever, described volume control device and described flow measurement device connect successively, and described pressure-detecting device is connected between described reliever and described volume control device.A kind of gas leakage alarm, comprises interconnective gas leakage alarm main frame and described transmitters sense device.Transmitters sense device of the present invention comprises reliever, pressure-detecting device, volume control device, flow measurement device and gas storage device, the gas of principal component is stored in gas storage device, gas enters transmitter to be detected by described transmitters sense device, because transmitters sense device can control (adjustment) the gaseous tension in deflation course and gas flow, and the gas storing known composition in gas storage device can verify that whether the transmitters monitor gas componant numerical value in Leakage Gas monitoring alarm is accurate, reaction velocity and detection sensitivity whether qualified, guarantee that Leakage Gas monitoring alarm can accurately be monitored indoor substation Leakage Gas.
