Abstract
The utility model relates to a switch device, more particularly to a remote-local bilateral control switch assembly. In the prior art, only a control switch is arranged near the existing mechanical equipment; therefore, when the equipment works under the severe working condition or in case of emergency, a monitoring center on duty can not realize remote turning off operation on the mechanical equipment. In order to solve the problem, the remote-local bilateral control switch assembly is provided. A local control switch is connected in series with a remote control switch; a selection end of the local control switch is one end for connection of the remote-local bilateral control switch assembly and a power supply; a first selection contact of the local control switch is connected with a first selection contact of a remote control switch; a second selection contact of the local control switch is connected with a second selection contact of the remote control switch; and a selection end of the remote control switch is one end for connection of the remote-local bilateral control switch assembly and a load. The provided remote-local bilateral control switch assembly can be widely applied to occasions requiring remote-local bilateral control of various mechanical devices.
Description
Technical field
The utility model relates to switchgear.
Background technology
At present, generally only near equipment, be provided with a gauge tap on the plant equipment in the workshop of factory, be used for opening and shutting off of opertaing device.If but in the process that plant equipment is moved under the special operation conditions such as high temperature, high pressure, operating personnel need to emit high pressure, high temperature equivalent risk to carry out switching manipulation near plant equipment.In case and plant equipment is in an emergency in operational process, can't be by operations such as Surveillance center on duty realize that the far-end of plant equipment is closed down, only can wait for that operating personnel arrive the target scene and operate, incur loss through delay the optimum operation time, cause unnecessary industrial accident.
The utility model content
Existing machinery equipment is existing only to be provided with a gauge tap to the utility model near equipment in order to solve, when equipment is operated in bad working environments or is in an emergency, can't realize the far-end of plant equipment is closed down by Surveillance center on duty the problem of operation; And the switchgear with far-end control function that proposes.
The two-way gauge tap assembly of a kind of far-end and local side, it is comprised of far-end and the two-way gauge tap assembly of local side; One end of the two-way gauge tap assembly of described far-end and local side links to each other with power supply, and the other end of the two-way gauge tap assembly of described far-end and local side links to each other with load; The two-way gauge tap assembly of described far-end and local side is comprised of local side gauge tap and remote control switch; Described local side gauge tap and remote control switch are connected in series; The selecting side of described local side gauge tap is the end that the two-way gauge tap assembly of far-end and local side links to each other with power supply; First of described local side gauge tap selects the contact to select the contact to link to each other with first of remote control switch; Second of described local side gauge tap selects the contact to select the contact to link to each other with second of remote control switch; The selecting side of described remote control switch is the end that the two-way gauge tap assembly of far-end and local side links to each other with load.
The beneficial effects of the utility model comprise local side and the two-way control of far-end that can realize plant equipment.Greatly improve the close down speed of equipment when being in an emergency, reduced the probability that industrial accident occurs; And when equipment is operated in more abominable operating mode, can realize that the far-end of equipment opens and shuts off control by remote control switch, and reduce operating personnel near the number of times of rugged surroundings operation, greatly improved equipment security in process of production.The utility model can be widely used in carrying out all kinds of plant equipment the occasion of local side and the two-way control of far-end.
Description of drawings
Fig. 1 is the described electrical block diagram with switchgear of far-end control function of the application.
Embodiment
Embodiment one, in conjunction with Fig. 1 this embodiment is described, the described a kind of far-end of this embodiment and the two-way gauge tap assembly of local side, it is comprised of far-end and the two-way gauge tap assembly 1 of local side; One end of the two-way gauge tap assembly 1 of described far-end and local side links to each other with power supply 2, and the other end of the two-way gauge tap assembly 1 of described far-end and local side links to each other with load 3; The two-way gauge tap assembly 1 of described far-end and local side is comprised of local side gauge tap 1-1 and remote control switch 1-2; Described local side gauge tap 1-1 and remote control switch 1-2 are connected in series; The selecting side of described local side gauge tap 1-1 is the end that the two-way gauge tap assembly 1 of far-end and local side links to each other with power supply 2; First of described local side gauge tap 1-1 selects the contact to select the contact to link to each other with first of remote control switch 1-2; Second of described local side gauge tap 1-1 selects the contact to select the contact to link to each other with second of remote control switch 1-2; The selecting side of described remote control switch 1-2 is the end that the two-way gauge tap assembly 1 of far-end and local side links to each other with load 3.
The difference of embodiment two, this embodiment and embodiment one is that described local side gauge tap 1-1 and remote control switch 1-2 all adopt single-pole double-throw switch (SPDT).
