Abstract
The utility model discloses a methane detection outage safety type anti-explosion chopping speed controller. The chopping speed controller is installed in an anti-explosion outer shell, a power source input wire of the chopping speed controller is connected with a methane outage module in series, and an intrinsic safety type methane detection sensor is installed outside the anti-explosion outer shell and is connected with the methane outage module through a signal wire. The methane detection outage safety type anti-explosion chopping speed controller has the advantages that the power source input wire installed on the chopping speed controller in the anti-explosion outer shell of the anti-explosion chopping speed controller is connected with the methane outage module in series, and the intrinsic safety type methane detection sensor is connected with the methane outage module through the signal wire and is used for detecting the concentration of methane at the position where an electric locomotive is located. When the detected result shows that the concentration of methane is lower than the outage value preset by the methane outage module, a contactor is actuated, electricity is supplied to the anti-explosion chopping speed controller, and the electric locomotive can be driven normally. When the intrinsic safety type methane detection sensor detects that the concentration of methane at the position where the electric locomotive is located reaches or exceeds the preset value, the methane outage module is powered off immediately, or the contactor is not actuated, the power source of the anti-explosion chopping speed controller is cut off, and then the safety is ensured.
Description
Technical field
The utility model relates to the explosion-proof chopper speed regulator of a kind of mining electric locomotive.
Background technology
For the explosion-proof chopper speed regulator on mining electric locomotive, there is the speed governing response fast at present, efficiency is high, the energy-saving effect outstanding feature, because mining electric locomotive is used for colliery, there is methane gas in coal mine, in order to guarantee safety, must control the indoor location methane detector the mining electric locomotive driver, and also must the harness standby explosion prevention function of methane detector, due to mining electric locomotive driver control cabin narrow space, an explosion-proof chopper speed regulator and a methane detector are installed simultaneously, make the space of electric locomotive crowded, the bad operation of driver, explosion-proof chopper speed regulator and methane detector have the explosion-resistant enclosure of oneself, cause the waste in production, and explosion-proof chopper speed regulator and methane detector all must obtain certification of conformity of an instrument for explosive atmosphere, product under certification of conformity of an instrument for explosive atmosphere all can produce overhead charges, and cause productive costs.
The utility model content
The purpose of this utility model is to provide a kind of methane and detects outage explosion-proofing safe chopper speed regulator.
The technical solution of the utility model is, a kind of methane detects outage explosion-proofing safe chopper speed regulator, chopper speed regulator is contained in explosion-resistant enclosure, serial connection methane power-off modular on the chopper speed regulator power input line, be provided with intrinsic safety type methane detecting sensor outside explosion-resistant enclosure, intrinsic safety type methane detecting sensor connects the methane power-off modular by signal wire (SW).
The utlity model has following technique effect, serial connection methane power-off modular on the power input line of the chopper speed regulator dress in the explosion-resistant enclosure of explosion-proof chopper speed regulator, intrinsic safety type methane detecting sensor connects the methane power-off modular by signal wire (SW), intrinsic safety type methane detecting sensor detects the methane concentration of electric locomotive position, during the power-down value preset lower than the methane power-off modular of the result after detecting, the contactless switch adhesive, explosion-proof chopper speed regulator obtains electric, and electric locomotive can normally travel; When the methane concentration of intrinsic safety type methane detecting sensor detection electric locomotive position meets or exceeds preset power-down value, the alkane power-off modular cuts off the power supply or not adhesive of contactless switch immediately, cuts off explosion-proof chopper speed regulator power supply, to guarantee safety.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is circuit block diagram of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of methane detects outage explosion-proofing safe chopper speed regulator, chopper speed regulator 1 is contained in explosion-resistant enclosure 2, serial connection methane power-off modular 3 on chopper speed regulator 1 power input line 4, be provided with intrinsic safety type methane detecting sensor 5 outside explosion-resistant enclosure 2, intrinsic safety type methane detecting sensor 5 connects methane power-off modular 3 by signal wire (SW) 6.
