Description

KYN61 switchgear handcart operating device

technical field

The invention relates to a high-voltage switchgear operating device in an electric power system, in particular to a KYN61 type switchgear handcart operating device with simple operation and good use effect.

Background technique

As we all know, the switch cabinet handcart operating device is an important equipment for operating the switch handcart in the substation. A reliable switch handcart operating device is an important guarantee for the safe and stable operation of people, power grids and equipment. The "Safety Operation Regulations for Isolation Switches" clearly stipulates that the closing operation of the isolating switch must be fast and decisive, so that the contacts are in good contact; when the isolating switch is opened, when the blade leaves the fixed contact, it should be quickly, especially to cut off the air of the transformer. When carrying current, charging current of overhead lines and cables, small load current of overhead lines, and cutting off loop current, the switch should be pulled up quickly and decisively so as to eliminate the arc. The handle is an essential tool for the high-voltage switchgear handcart to operate the circuit breaker handcart to change its working position. The operating handle of the ordinary switch cabinet handcart is a right-angle rocker, which is provided with an operating rod. One end of the operating rod is provided with a joint, and the other end passes through the rocker arm. The arm is perpendicular to the operating rod and the handle. When operating, the joint is buckled into the operating hole of the handcart. The operator needs to shake the handle hard to rotate the operating rod, so that the handcart can switch between different working positions. In large-scale switching operations, multiple The continuous operation of the heavy-duty handcart will cause excessive physical exertion of the operator; and because the center of gravity of the right-angle crank handle is on the handle of the crank handle, the handle will fall off when shaking. When the handcart is being shaken in and out of the switch cabinet, if the moving and static contacts of the handcart are in contact and the handle falls off, it will easily cause a high-voltage arc and endanger the safety of equipment and personnel.

Contents of the invention

The purpose of this utility model is to overcome the deficiencies of the prior art, and provide a KYN61 type switchgear handcart operating device with simple operation, good use effect and shortened power-off and transmission time.

The utility model can be achieved through the following measures:

A KYN61 type switch cabinet handcart operating device is provided with an operating rod, one end of the operating rod is provided with a joint, the other end of the operating rod is provided with a rocker arm perpendicular to the operating rod, and the other end of the rocking arm is provided with a The parallel handle is characterized in that the other end of the crank is connected with one end of the connecting rod, the other end of the connecting rod is connected with one end of the push rod, and the other end of the push rod is connected with the push plate through a bearing.

The connecting rod described in the utility model is perpendicular to the handle and the push rod, and the axes of the push rod and the operating rod coincide, so that the thrust of the push plate is directly facing the joint through the operating rod, so that the connection between the joint and the operation hole of the handcart is reliable. .

The handle of the utility model is provided with a sleeve, and the operator holds the sleeve and rotates the handle to facilitate operation and slow down the rotation resistance of the handle.

The push plate described in the utility model is provided with a counting display through the bracket, and the push rod is provided with a rotation sensor, which is electrically connected with the counting display, so as to visually judge the position of the switch cabinet handcart through the counting display.

When the utility model is in use, insert the joint into the handcart operating hole, make the push rod and the operating rod face the handcart operating hole through the push plate and give the push plate a thrust to ensure that the joint does not fall off when rotating, and then drive the operating rod through the push handle The joint rotates to switch the working position of the handcart of the high-voltage switchgear, which has the advantages of ensuring the accurate operation of the handcart's reversing brake, simple and convenient operation, saving the physical strength of the operator, and ensuring the safety of equipment and operators.

Fig. 1 is a kind of structural representation of the utility model.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in the figure, a KYN61 type switch cabinet handcart operating device is provided with an operating rod 1, one end of the operating rod 1 is provided with a joint 2, and the other end of the operating rod 1 is provided with a rocker 7 perpendicular to the operating rod. The other end of the rocking arm 7 is provided with a handle 3 that is parallel to the operating rod. The structure of the above-mentioned components and the interconnection relationship between them are the same as those of the prior art. The other end of 3 is connected with one end of connecting rod 4, and the other end of connecting rod 4 is connected with one end of push rod 5, and the other end of push rod 5 is connected with push plate 6 through bearing, and described connecting rod 4 is connected with rocker The handle 3 and the push rod 5 are vertical, the connecting rod 4 and the rocker arm 7 are parallel to each other, and the axis of the push rod 5 coincides with the axis of the operating rod 1, so that the thrust of the push plate 6 faces the joint 2 through the operating rod 1, so that the joint 2. The combination with the operation hole of the handcart is reliable. There is a sleeve on the handle 3, and the sleeve can rotate around the handle. The operator holds the sleeve and rotates the handle to facilitate operation and slow down. The rotation resistance of the handle is small. In addition, the push plate 6 described in the utility model is provided with a counting display 8 through the bracket, and the push rod 5 is provided with a rotation sensor, and the rotation sensor is electrically connected with the counting display, so as to visually judge the position of the switch cabinet handcart through the counting display, The structure of the rotation sensor and the counting display and the interconnection relationship between them are the same as those of the prior art, so I won’t go into details here. When the utility model is used, the joint is inserted into the handcart operating hole, and the push rod and the operating rod are facing each other through the push plate. Car operation hole and give a push to the push plate to ensure that the joint does not fall off when rotating, and then use the handle to drive the operating rod to drive the joint to rotate and switch the working position of the high-voltage switch cabinet handcart. It has the advantages of saving the physical strength of the operator and ensuring the safety of equipment and operators.
