This installation and instruction manual is written using the CSH-B as the focus. The guidelines provided should also be utilized when installing the CSH2-B. This manual can also be used as a guide for the CSH and CSH2 products which are similar but do not have the integral disconnect.
Operation of the Southern States CSH-B is controlled by a motor operator or by a manual worm gear operator. The Southern States CSH-B is designed and certified to switch and protect transformers. The horizontal circuit switcher is also available without the integral disconnect (CSH).
Overview The Type CSH is similar to the Type CSH-B. The CSH units do not have an integral disconnect blade. Line termination is on the driver end. Two, rather than three insulator columns are used to support and operate the interrupter.

The interrupter is an SF puffer design. The contact structure is robust and designed for many switching operations. The CSH-B also utilizes a rupture disk that is designed to vent the gas in the event of an overpressure condition inside the interrupter.

Product Description Operating Mechanism A typical three-pole arrangement of the CSH-B is shown in Figure 6: Operating Mechanism. The three single pole units are mechanically connected to operate simultaneously from a single operator, similar to group operation of a disconnect switch.

Appendix A-1 to RFP / Page 20 of 90 pages. Page 10 of 78 Product Description Driver The driver mechanism located at the top of the rotating insulator column contains the main closing springs, shunt trip charging bolt, trip latch, and lever system that controls interrupter opening and closing. The main operating shaft of the driver also operates the hinge mechanism of the disconnect switch.
Appendix A-1 to RFP / Page 21 of 90 pages. Page 11 of 78 Product Description Shunt Trip The shunt trip mechanism is a stored energy device with a trip coil that imparts high speed tripping to the interrupter. Energizing the trip coil releases a latch causing a spring to discharge, producing rapid rotation of the insulator (Figure 10: Shunt Trip).

The motor operator is shown in Figure 12: Motor Operator (Outer). The operator has high torque for use with a CSH-B and can be electrically operated from a remote station. Standard features include an all-aluminum enclosure with corrosion resistant fittings, swing out removable doors, local electrical and manual operation, position indicating lights, thermostatically controlled space heater, operations counter, provision for a security lock, a decoupler, and an internal auxiliary switch.

With the handle in the up position, as shown, the locking pin is engaged in the output shaft slot. Because of the force imposed by the shunt trip charging springs when the CSH-B is in the open position, it is necessary to use the hand crank to decouple.

There is a latch indicator on the underside of the housing of each driver. The painted marks serve to indicate limits of travel of the driver shaft and are used during installation and adjustment of the CSH-B operating linkage. They have no other function and should not be used for any other purpose.
To open the CSH-B, operate the crank handle in the direction indicated on the sticker above the hand crank insertion point. Approximately three turns will open the interrupter. Crank from stop to stop on the outboard bearing lever in order to properly complete an opening or closing sequence.
Page 21 of 78 Product Description Control Circuits Further detail can be found in the motor operator’s instruction book and in the customer drawings. This is a typical arrangement; consult customer drawings for the actual wiring of this particular CSH-B.

How to Read the SF Density Gauge The Southern States CSH-B interrupter unit is equipped with a temperature compensated pressure gauge. The temperature compensated pressure gauge displays a constant pressure reading over the ambient temperature range of the switcher. Refer to Figure 22: Gauge Face.
Death by suffocation is possible. The Southern States CSH-B is packaged for shipment by the following two methods. Structure members (structural frame and support columns), when furnished by Southern States, are in a separate shipping group.

Troubleshooting Guide Apparent Problem Possible Solutions An Outside Pole Does Not Close Insufficient shunt trip gap in the open position. Adjust for gap with the shunt trip charging bolt. Screwing in on the charging bolt to obtain more gap reduces rotation into the green band.
Appendix Appendix E. Trip-Free Operation/Testing The Southern States Type CSH(2) and CSH(2)-B horizontal circuit switchers are designed so that, if inadvertently closed into a fault, the switcher will immediately open and interrupt the fault. The opening springs and the shunt trips are charged at the end of the opening stroke. So, when a closing operation is commanded, the opening mechanism is already set to open the interrupters.
