Detailed Description
In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings. The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and processes are omitted so as to not unnecessarily limit the invention.
The following combines the figure to be right the utility model provides an alternating current-direct current fills electric pile scram button self-resuming circuit and carries out the detailed description.
As shown in fig. 1, the utility model discloses an alternating current-direct current fills electric pile emergency stop button self-resuming circuit, the circuit includes:
the device comprises a main control board, an isolation circuit, a mushroom button, an onboard miniature relay, an intermediate relay and a direct current output relay/alternating current contactor;
the mushroom button group is normally opened and is connected with the intermediate relay group in parallel, and is connected with a normally closed port of an onboard miniature relay on the main control board in series to be connected with an intermediate relay coil control loop;
the mushroom button group is normally opened and connected to a master control remote signal through an isolation circuit;
and a group of normally closed intermediate relays is connected to a direct current relay control loop or an alternating current contactor control loop.
The mushroom button is a circular self-resetting mushroom button with two groups of normally open contacts, when the mushroom button is pressed down, the two groups of normally open contacts are closed, and when the mushroom button is released, the two groups of normally open contacts are opened.
The isolation circuit converts a direct current level signal into a low-voltage control signal or converts the low-voltage control signal into a direct current driving signal of the control coil by using an optical isolation mode, so that the onboard small relay coil is electrified to promote the actuation or disconnection of the secondary contact, and the actuation and the disconnection of the intermediate relay are controlled.
The intermediate relay is a group of normally open contacts and a group of normally closed contacts, when electricity exists in the coil, the normally open contacts are driven to be closed and the normally closed contacts are driven to be opened through an electromagnetic effect, when the electricity is cut off in the coil, the normally open contacts are restored to be opened, and the normally closed contacts are restored to be closed.
The onboard miniature relay is a group of normally closed contacts, the normally closed contacts are driven to be disconnected through an electromagnetic effect when electricity exists in a coil, and the normally open contacts are driven to be closed by a spring when the coil is interrupted.
The high-power coil is arranged in the alternating current contactor, when the coil is electrified, the main contact is driven to be attracted through an electromagnetic effect, and when the coil is powered off, the contact is driven to be disconnected through the spring.
The direct current output relay is internally provided with a high-power coil, when the coil is electrified, the main contact is driven to be attracted through an electromagnetic effect, and when the coil is interrupted, the contact is driven to be disconnected by a spring.
When the relay normally works, the intermediate relay is in a power-off state, the normally closed contact is in a closed state, the coil of the direct-current output relay is electrified, the main contact is attracted, and the output end outputs a signal.
When the mushroom button is pressed, the normally open contact is closed, the master control remote signaling changes, an emergency stop fault is reported, the intermediate relay coil is electrified, the normally open contact is closed after the electrification, and meanwhile, the normally closed contact is disconnected, so that the direct current relay or the alternating current contactor is powered off, and the output end stops outputting. When the mushroom button is released, the normally open contact of the mushroom button is switched to the off state from the on state, the normally open contact in the intermediate relay is always in the on state, and a passage is formed between the normally closed contact and the normally closed remote control port of the main control board, so that the coil of the intermediate relay is kept continuously electrified, the normally closed contact of the intermediate relay is always in the off state, and the direct current output relay/alternating current contactor is continuously powered off.
After the output stops exporting, carry out equipment self-checking, after the self-checking is accomplished, fortune dimension distal end judges whether equipment can resume, when can resuming, issue the instruction of resuming, the small-size relay coil circular telegram of main control board carrier, the disconnection of normally closed remote control mouth, because the normally closed contact disconnection of board carrier small-size relay, the access disconnection that original auxiliary relay and main control board formed, auxiliary relay loses the electricity, thereby auxiliary relay's normally closed contact resumes the closed state by the off-state, normally open contact resumes to the off-state by the closed state, thereby resume the output of output, fill electric pile and resume normal condition.
In addition, the main control shutdown can be remotely carried out, an onboard small relay is arranged on a direct current relay control loop or an alternating current contactor control loop on the main control board, the contact of the onboard small relay is in a normally closed state under the non-electrified state, and the normally closed contact is in a disconnected state under the electrified state, so that the active shutdown is controlled.
The utility model discloses a mushroom button is from resetting and relay circular telegram auto-lock, has realized pressing the mushroom button, and remote signalling change is received in the master control, and the relay auto-lock has simultaneously cut off direct current output relay or ac contactor's control circuit, has effectively kept emergency stop button function, has added the onboard miniature relay simultaneously, can long-range relay's control circuit that cuts off, and the messenger fills electric pile equipment and resumes normally. This practicality is on the basis that does not change original structural design, is convenient for carry out and reform transform, does not influence original function to in normal use, not intervene normal charging flow, reduced the circuit fault rate, and adopt the remote signalling feedback of master control, two kinds of output measures that stop of master control initiative shut down and output relay outage, in order to guarantee personal safety, reduced fortune dimension spending, improved the availability factor who fills electric pile.
